They say I need a treatment too.
This is a tricky one, and this answer is only for subterranean termites (not for drywoods and not for dampwoods).
Let's say the termites are in your neighbor's house. A nearby infestation means that local conditions are suitable for the termites and so it tells you that your place is also at some risk. If baits or another colony-killing method is used, then that immediate risk to your house is gone as that colony will be controlled. But there may well be many nearby colonies. If they just repair the damage or poison the ground with a repellent chemical (like bifenthrin), then the termites may be 'pushed' towards feeding at your place. That isn't good.
On the other hand, the termites may be living in your house and have spread to your neighbor's. Or they may be nesting in your yard.
In any case, this is not the time to sign up for a treatment. You should get a proper timber pest inspection done so that you can assess your options. Then talk to your neighbor about the best way to do things.
My house looks just like the ones that don't have termites.
Termites have no capacity for malice, so it is definitely nothing personal. Their needs are simple. Food and shelter are almost always freely available for them in what we build. Water is the big issue and often we can build termites out by making it harder for them to get the water they need so that they can eat.
The best thing you can do is to get a professional inspection report done and read the report carefully. Next best is to keep reading and try and work it out for yourself. What has changed? In what subtle ways is my house differently exposed? Did anything make it easy for them? How are they getting in? Why is water available? If you can answer these, you're most of the way to selecting a solution.
It might, but don't count on it. Baits are not prophylactic. Baits are good at grabbing termites' attention and can be used to slowly poison their colony BUT baits are not barriers and it is possible for termites to ignore them and eat your home anyway. The baits don't make a continuous wall around the house, so termites may just walk between them. The termites mightn't find the baits, the baits might be poorly placed, they mightn't suit your termites, they might be too often disturbed or left too long, too wet or too dry, they might have the wrong food or they might have gone mouldy. Baits are great at cutting populations and even killing colonies, but it is probably best that you add other ways to keep termites out of your home, just to be sure. Of course if the service company is offering you a contract with a strong warranty, maybe you can take the risk. Just make sure that all the checks and inspections are done, that you keep all the records and that the company is well insured.
A flood or heavy rain can seriously upset your termite defenses.
If you rely on soil chemical chemicals around or under your home, these can be buried by silt and debris making a bridge for the termites. The chemicals can also be washed out, so when the water goes away, check and organise a termite inspection a few weeks later.
Water that gets into your house (but not out again) tends to soak into timbers. Termites love to eat timber that's damp. Fungi (rot) also has a better time and wood that's partly rotted by fungi is often tastier for termites.
Subterranean termites have trouble getting around when their tunnels are full of water. If you scale it up, it is a bit like you or me trying to walk through honey. So they stay home or move to wherever is high and dry(ish). When the water drains away some of their tunnels will need repair and may be abandoned. They'll move quickly to patch up access to their best food resources. Scary thing is that all that moisture in the soil makes their tunneling so much easier as they no longer need to carry in water to work. So, once re-established, subterraneans will go exploring and your barriers will be tested. After a flood or after drought-breaking rains, you should schedule an inspection the next Spring or Fall (Autumn), certainly before six months are up.
Floods can also move big bits of wood around. Sometimes these bits arrive with termite colonies inside. Sometimes floods cause timbers to be buried or mostly buried. Timbers that are in the soil are much nicer for termites as they don't dry out quickly and the soil buffers temperature changes. Floods change things.
If flood waters sit around for extended periods, weeks or months, then termites populations may be reduced for a time.
Every building should be designed to reduce the chances of problems with all the local pests, not just pest termites. Here's a basic scheme:
- Much can be done to reduce the pest pressure and maintenance costs by including a few simple design features. While my main interest is the exclusion of subterranean termites, design should take account of all likely pests. The following guidelines are intended for architects, designers and managers of large facilities (schools, nursing homes, hospitals, offices etc.) but may be adapted to any construction.
- Most pests will take advantage of concealed entry paths. Accordingly, the perimeter of a building should be designed and constructed so that:
- Pests are discouraged from gaining easy entrance.
- Door should fit snugly with weather stripping and sweeps that close tightly.
- All opening windows shall have metal screens which are fixed taught and seal to the frame with a gasket.
- All metal window and door frames shall have joints sealed with a suitable elastomeric sealant.
- Cracks, crevices, holes and thermal gaps shall be suitable sealed with a caulk or compressible foam product.
- Large holes such as for added or removed pipe openings shall be sealed. Stainless steel wool (pot scrubbers) covered with a mortar or grout is usually sufficient.
- Exterior lighting for doors must be far enough away that flying pests attracted to the lights can gain casual entry. Entrance ways should use reflected rather than direct light and light sources should be at the orange end of the spectrum so as to reduce attraction to nigh-flying insects.
- Entrance ways, alcoves and attached plant should be designed so as to minimise wind-blown debris accumulation.
- All pests need somewhere to live and somewhere to rest.
- Pests should not find easy hiding places inside.
- Interior wall joints, gaps in panels, window frames, gaps around cupboards and electrical fixtures shall be filled or sealed.
- Skirting boards, and floor coverings shall provide no open cavities.
- Skirting boards and sheet floor coverings shall be designed and placed so as to be readily cleaned with electrical rotating brush devices. There should not be internal 90 degree corners, rather corners should be radiused to match cleaning capability.
- All supply pipes, cables and conduits to be sealed where they pass through walls and panels and, all conduits and ducts to be sealed or meshed to prevent pest entry.
- In kitchen, bathrooms and other wet areas, cabinets, sinks, toilets and counter tops which meet walls shall be sealed against water entry so as to prevent pest harbourage.
- Air vents/inlets shall be screened with metal mesh of 1 mm aperture size (small enough to block termites) which is fabricated and installed so as to be readily removable for cleaning.
- Floor drains require removable coarse mesh screens or similar devices to prevent cockroach passage.
- In kitchen, bathrooms and other wet areas, floor-mounted fixtures should, as far as practicable, be either on raised legs (100 mm high) set as to provide easy access for cleaning and inspection or shall be provided with sufficient space for easy access and cleaning ( e.g. toilet cubicles).
- In kitchen, bathrooms and other wet areas, drains shall not be concealed under equipment or fixtures.
- Storage areas should be designed to permit both inspection and drying air flows. Storage units should be mounted at least 100 mm off the floor. Racks, cupboards or compactus units for long-term storage shall mounted be at least 600 mm from walls.
- Pests should not find easy resting places outside.
- Ledges and fixtures should not provide roosting places for birds as faecal accumulations pose a health hazard.
- Plant and equipment whether at the perimeter or roof-mounted, should be designed to exclude rodents and bids and to be readily inspected.
-
Roof should be designed to shed booth water and litter.
- All pests need a suitable environment in which to live. A building's immediate surrounds should not be particularly amenable to the pests' needs.
- Exterior landscaping can create ideal pest environments.
- Gardens must not be adjacent to exterior walls such that, at any time, plants will be in direct contact. Plants provide bridges for pests.
- Paving at least 600 mm wide should surround the building. In low-traffic areas, paving can be replaced by compacted gravel. Paving is less hospitable than garden beds.
- Plants, including grasses, should not encroach on perimeter paving.
- No tree,shrub or plant that is known to have extensive or invasive roots (e.g. Bamboo) shall be planted within 3 metres of the exterior walls. Where such plantings are identified, foundations and perimeter paving shall be protected with a root barrier system.
- Trees, shrubs and other large ornamental plants shall be spaced to have a free-air gap of at least 600 mm between them at maturity (or to be trimmed to maintain such gaps). Air gaps are important to reduce humidity at the exterior of the building.
- Soil levels, paving, features and garden beds shall not interrupt the fall so that rain and other water drains well away (at least 2 m) from the base of perimeter walls.
- Garbage and recycling containers for litter shall be mounted on concrete pads which extend not less that 150 mm from the container. Containers shall be mounted not less that 400 mm from walls and shall be positioned on legs to provide at least 100 mm clearance from the pad. Containers shall have self-closing lids.Termites in particular can be encouraged by having concealed access points to the building fabric and by having water and potential food in close proximity.
- Buildings should be intrinsically termite resistant.
- Physical termite barriers that do not rely on any toxin should be used wherever possible as these generally provide the longest service life.
- Footings, retaining walls and any section of wall that might be concealed by soil of accumulations from garden beds etc. should be solid rather than hollow and should have all joints and expansion gaps fitted with a suitable termite barrier.
- Moisture and water must not be allowed to accumulate either under the building or against exterior walls. Service life is extended where the perimeter and footing earth stays close to uniform moisture content. Pests problems are reduced where this moisture content remains low.
- The roof should be pitched and drain to the exterior. Valleys should be steep to rapidly shed water and litter. Flat roof designs that permit either water ponding or wind-blown litter and bird wastes to accumulate are to be avoided. Subterranean termites will attack a building from the top where there is permanent moisture.
- Timbers in soil contact shall be kept to an absolute minimum and where required only known naturally resistant or suitably preserved timbers should be used. Landscaping timbers decay to become major harbourages for pests. Preserved timbers weather and degrade over time and may provide cover for pests. Where preservative penetration is insufficient, pests may be concealed within apparently preserved timbers.
Trust and confidence need to be established. Will this pest manager do a good, competent job at a fair price? There are some slick and very shonky sales people out there ready to rip you off. There are honest pest managers who just want to give you a good job at a fair price. There are big companies and small companies, caring companies and careless companies. How can you decide who to employ?
Here's a few simple pointers. I hope they help.
- The Need: Don't be rushed. Chances are you have plenty of time to consider your options. Termites work slowly and so may you. Take your time and make the right choices. Consider how you know what you know. Keep notes of all conversations and keep your paper trail.
- The Business: The preferred way to find the right business is by talking with your friends and finding out who they have used successfully. Word-of-mouth keeps many successful businesses thriving.
How secure is the business?
Does it have a bad name?
Are they afraid to answer your questions?
Does the mention of their name ring alarm bells at your local consumer advocacy/complaints group?
Can they provide the names of satisfied customers as referees?
Don't necessarily feel that big is better; an apparently large company may turn out to be just loosely controlled franchises, offering at best no better service than their smaller competition.The quality of the job will only be as good as the person who carries it out. Will the person actually doing the work be well trained and knowledgeable and able to talk with you or are you dealing with a salesperson who can only provide the quotation?
- Face to Face: Meet them on your own turf, not their's. Depending on the nature of the problem, many pest controllers will provide a quotation either at no cost or fairly inexpensively. They may be prepared to just turn up and talk with you while requiring a fee before they'll do any inspection. This is fair, as any information they provide on the basis of inspection whether free or at cost, implies at least some professional responsibility and hence potential liability on their part. Beware the "free" inspection. Everything has to be paid for eventually, by somebody, sometime. Separate the inspection from the control proposal. Make sure that you get a proper (on paper) timber pest inspection (WDO, or 'Wood Destroying Organism") report and make sure that it identifies the pests as far as possible.
- Safety in Numbers: Approach at least two or three businesses. Compare their advice and quotations. Decide whom you would best trust with your assets. Then compare prices. Beware the surprisingly cheap quotation. It is easy to do a cursory inspection and to excessively dilute any expensive chemicals, or just not apply them where they should go. Remember the value of a good warranty. Read Claire's experience. Know the different ways termites can be managed and why the one proposed is thought best for you.
- The Fine Print: What does the paperwork look like?Ask to see it up front. After an inspection, you should be handed a written report, usually with a site diagram and the problem areas at least approximately mapped. The information should be clear. If it is presented on a preprinted form, the notations should be informative and quite clear. Look over the warranty. How small is the fine print? Do they mind you reading the contract? Is the scope of work made fully clear and is sufficient detail present to enable you to compare and contrast the quotes? Ideally, you will be asked to sign an agreement before any work occurs. That's a good way to ensure you have matching expectations.
- A Relationship?: What about contracts? Are you just getting them to fix today's problem or are you signing up for a never-ending dependency? What if you sign and you don't want them back again? What if termites come back in one, two or three years? What will they do then? If they've done good work, should you pay a maintenance fee for the year on top of the other costs? It is always important to check value for money. Maybe that service contract is aimed more at maximising income rather than minimising termites? You have to work it all out. There's often comfort in a trusted name, but you should put at least as much weight on local people's experiences as you do on brand recognition. Don't get me wrong, sometimes service contracts are the way to go, especially with a baiting program where you want it all planned out and costed in advance.
- Deciding: Take some time to think over the information you have gathered. One of the best ways is to get out of the house/office and go for a walk. You'll think much more clearly.

Actions to stop or control termites need not be scary.
Termite control comes in four forms: cultural, physical, biological and chemical.
Well, at least those are the headings used in most text books.
Chemical control is the least desirable, but is sometimes the only option.

Cultural control relates to what we do and the way that we do it. It pays to avoid the simple traps that make things inviting for termites. In tropical North Queensland, where life is excellent for pest termites, the old traditional wooden housing style sits up very high. The tall stumps and metal termite caps (inverted pie plates) provide excellent protection against sneaky termites. They can still come in from the ground, but it is far from inviting and they have to build shelter tubes over the pie plates. Not a great option for them and one which makes them very easy to spot. If you follow the "guide to avoiding termite problems" you are instituting a cultural control by reducing the termites' chances of getting a foothold. Nomadism is another cultural technique--it sort of parallels with disposable coffee cups, only this way it's your home that is short-lived. Some speculative builders seem to prefer this approach. Beware the short warranty. Keeping a horde of animals to eat swarming termites has to be helpful. Geckoes on the walls will eat many termites. Ants are perhaps the best and most persistent predators, cleaning up the bulk of each alate flight. Even chickens will make short work of termites as they try to extend their shelter tubes.
Physical control separates the food from the termite. Strip shielding, pie plates, posts on stirrups, and physical barrier systems such as Granitgard and exposed slab edges are examples of physical controls. Termites can also be controlled by taking their environment beyond the normal limits that their bodies can take. To this end, both sustained heat (over about 45 degrees C for an hour or so) or sustained cold (subzero--it is the ice-crystals that kill) can been used. Some services also use microwave energy--waves cook things well inside a tightly shielded oven, but it is fairly difficult to control such energy in a structure, where reflection is hard to predict, so be careful out there! These methods are not always a DIY option. Other proposed physical controls include eletrocution (in timber and soil) and bizarre electronic and sound repellents. Be wary of techniques that appear dangerous or hard to believe. If scary sounds did repel termites, they probably wouldn't ever eat grade schools.
Biological control is practised for many other insect pests, but has had little success with termites. Well, little success in the commercial sense. As with the ants and geckoes mentioned above, many societies have used termites' natural enemies to keep them in check. Birds and ants can clean up an amazing quantity of termites. Business has tried nematodes and fungi. The nematodes are tiny worms which parasitise termites and the fungi are disease organisms, perhaps best thought of as terminal tinea. While these work extremely well in controlled laboratory experiments, they have yet to make a significant splash in the market. Still, we're all eagerly waiting and at the moment it looks like nematodes are slightly ahead of the fungi. Flies, beetles and killer viruses also kill termites, so who knows what will happen

Chemical control was once the sum total of pest controllers' responses to termite problems. Now the consequences of poisoning soils and surfaces are becoming apparent as the old termiticides are withdrawn and the newer ones come under increasing scrutiny. As most commonly practised, chemical control for termites involves either soil treatment to provide a barrier of toxic residues or (for drywoods) tenting of the structure and flooding it with toxic gas (some such fumigants may damage the ozone layer). To be effective, a chemical applied to form a toxic barrier in the soil must penetrate evenly and then bind securely to the soil particles. It has to be persistent. It must not break down through the action of normal soil microbes. Another way to use chemicals is (in much smaller doses) to apply them directly to the termites such as in the bait box technique, either as topical dust, or as bait toxicants. There is a world of difference between surrounding a structure with several kilos of toxin applied in hundreds of litres of emulsion and the at most, few grams of a slow-acting toxin which may be used in a baiting system (the bulk of which may be removed after control is achieved). Other than poisoning the soil and timber, chemicals are also used against drywood termites, but as a whole-structure fumigation or a spot treatment. Spot treatments are only for where you can be 100% sure that you can find and reach each and every drywood colony.
Integrated termite management is a fancy term for putting it all together. For integrated control, you must plan, act as required, monitor, adapt and review. Take the long-term view and you can save a lot of money. Particularly if you build well (with physical barriers) in the first place.
What to do first is usually straightforward. If you have drywood termites, the infestation is usually limited (sometimes to a single piece of furniture, sometimes to the whole house). For subterranean termites, management should first aim to either exclude the termites (such as by repairing a physical barrier) or kill off the offending colony. Colonies can most often be killed by nest destruction, nest poisoning, by baiting or by judicial use of a non-repellent termiticide into the soil where they are active. Repellent soil poisons are best (not used, or) saved for new construction when you can be sure of a complete barrier. In the ideal world, your pest management technician will do a full timber pest inspection of the building and grounds and present you with a written report and (separately) a management plan (hopefully with a range of options). Again, ideally, remedial soil poison barriers would not be used (i) unless necessary and (ii) until the offending colony had been controlled. Repairs (unless for safety) should not be made until the colony is controlled as early disturbance can make management difficult by breaking up or concealing the termite activity. If baiting or using a non-repellent termiticide for colony control, you want to keep them feeding at full tilt until they have consumed enough poison to kill the whole colony.
Here's a quick list of the main ways to kill or control termites
For Dampwood termites
- Take the moisture away so that they can't live.
- Replace old, rotted wood with fresh timbers.
- Apply poisons or preservatives into the wood.
- Open up the wood and let the ants eat them.
For Drywood termites
- Fumigation will kill all the termites.
- Tenting and heatng will kill them if everything gets hot enough.
- Extreme cold will also kill them. For example, an infested yacht can be taken to very cold waters for the winter and furniture and artefacts (if dry) can spend a while in a freezer.
- Spot-treatments with poisons can kill them, but you have to be sure to find, and adequately reach, each and every piece of infested timber. The risk of error is high.
For subterranean termites
- Killing the colony with direct applications of poisons is the surest approach if you can find the main nest(s).
- If you can't find nests, but have located leads (shelter tubes) and areas of high activity then applying a very slow-acting non-detectable poison (by dust, foam or liquid) cause it to be shared widely before any individuals die, thus having a good chance of killing the whole colony.
- If you know they're there but can't find good numbers, then baits can be used to aggregate large numbers for poisoning. Commercial bait systems often use very slow acting hormones and it may take weeks or months to see a result.
- Soil poisons to isolate a structure are best left to mopping-up or remedial barrier work but sprays of a non-repellent toxin (like chlorantraniliprole, fipronil or imidacloprid) can help reduce termite populations and may kill the colony (if you are lucky).
- Very rarely, a nest that is big, obvious and isolated can be physically removed, taking enough of the termites to cause colony collapse.
So, the bottom line is try to get rid of the whole colony as killing a few termites may not make much difference. Once you have achieved control, it is important to prevent future infestations from the same causes. For more details, check out the termite FAQs.
OK, so you've found termites. Here's a quick step guide of what to do.
- Don't spray anything. Spraying just makes the rest of them go to where they're hard to find.
- Don't disturb them. Often it is cheaper to control them if they are undisturbed.
- Don't panic. Termites tend to work slowly, so you usually have time to act before things get noticeably worse.
- Read through these FAQ files so you have a good background knowledge.
- Don't call the first company you find in the phone book. Take your time, find a good inspector get a written report, then work out what to do.
- Do fix up the things that attracted the termites in the first place.
- Do remember to have another inspection scheduled to make sure that things are really fixed.
- Do consider regular inspections so you can catch any new attacks early.
Simple ways to avoid meeting termites
In the wild, pest termites usually get by quite happily eating sickly trees or the leftover bits of trees, and the safest, moist and tasty bits are usually underground or right in the middle of big pieces of timber. If your home/building/structure has big bits of wood that are dark or damp or close to the soil then your chances of avoiding termite problems are reduced.

Subterranean & dampwood termites
Subterranean termites usually get about by tunneling underground and entering their food from below. Tree roots are usually attached to trees and termites often travel from root to root great distances underground (there's almost always a small air gap under a big root, so they don't even have to dig as much). Timber waste buried around buildings usually leads to better food inside. Sometimes the termites just fly in and start up a fresh colony, but tunnelling is more common, because big bits of damp wood suitable for nesting are more often outside, not in. Dampwood termites don't tunnel nearly as much but can fly in just as easily.
Since the termites are most likely to try to get in via the soil, there are some simple things you can do:
Control moisture:
- All types of termites need moisture. Keep your structure dry and well ventilated.
A free drink - Ventilate all possible subfloor areas and ensure the vents are kept free and clear. Make sure you wet areas inside (kitchen/bathroom/dungeon) are well vented. Wood can get wet, but must not stay wet.
- Fix all plumbing leaks. Particularly showers and baths. These often have leaks supplying constant moisture that makes the wood just right to be eaten.
- Check all gutters and down spouts, make sure that the water ends up well away from the house. Ideally down spouts should connect to stormwater drains. If you don't have these, at least redirect the water well away from the house. Down spouts which regularly splash near the structure may be supplying an irresistible source of moisture.
Biochemist's paving blunder - Avoid having gardens directly against walls--if you must do this, provide space for air movement between the vegetation and the wall and an inspection zone of at least 100 mm. Never have sprinklers wetting the soil near a building or deck. Termites have even been known to enter a building through branches touching walls.
- Make sure that any paving is angled to drain surface water away from the structure. You'd be amazed how often this is done wrong. Some people even build outdoor paving higher than the interior floor level . . . like in this photo of the paving around my house.
Be careful with timber in ground contact:
- Remove any timber or cellulose material stored on the ground beneath a suspended floor. That includes cardboard boxes and old newspapers, even cotton materials. Clean up any off cuts left during construction. The aim is to maximize the distance between termites and their potential meal.
Polystyrene - Don't store any firewood in ground contact. This attracts termites. It also prevents the wood drying properly and hence reduces the heat yield on burning (it takes energy to boil water). Set your firewood at least 100 mm above ground (a shelf ot trench-mesh sitting on cinder blocks is a cheap solution).
- Structural wood in ground contact should be either termite resistant or treated with a preservative. Better yet, cut it off and mount it on a metal stirrup set in concrete. High and dry is always best.
- Don't provide hidden entry points where temites can walk in unseen. Stucco can hide termite freeways and rigid foam slab-edge insulation can be a nightmare, providing termites with easy and secure tunnel space where you can't see them. Instead, provide an impervious inspection zone. Use long-life physical barriers in all new construction.
Hidden entry paths There's a trend in the USA now to have stone veneers in ground contact. All these concealing wall finishes create a major risk.
Drywood termites
Drywood termites can live in small pieces of wood so long as it is a little moist and not too hot or cold. They'll fly in and start their colonies right in that wood. Best way to keep them at bay is to disguise your timber.
- Too Dry:Keeping timber very dry will make it impossible for termites to live, but this is impractical in many tropical and coastal areas where the natural humidity is sufficient to keep the wood moist enough for drywood termites. Do what you can to keep timber as dry as possible.
- Disguised:If they don't know it is wood, they may not find it. Keep all exterior wood well coated with paint or varnish, especially the larger bits and at the joins and ends. Drywood termites begin their attack with just two termites. First the female selects a likely place to live and then pairs up with a male before they start tunnelling. So if you can make the wood unattractive, the termites won't even try. A bit of preservative can go a long way. If it doesn't taste good, the termites won't hang around.
- Inaccessible:If they can't get to the wood they can't eat it. Seal up any cracks or fissures (these make it easy for them to get in). Cover vents with fine mesh screening (about 0.8 to 1.0 mm openings--but remember, you may need to increase the vent size to make up for this restriction of air flow). Pay particular attention to the roof and wall frames.
Following these simple points will greatly reduce your termite hazard. Best of all is to design your structure to be termite resistant from the very beginning. Remember too, that regular inspections can locate termites before they do any major damage.
Trust and confidence need to be established. Will this pest manager do a good, competent job at a fair price? There are some slick and very shonky sales people out there ready to rip you off.

Detecting termites is hard because they like to hide
Termites are little white, soft-bodied weaklings. Termites avoid light and rarely come out into the open. Termite attack can escape anyone's notice for a very long time, which can be horribly expensive, not to mention dangerous. A lot of houses that collapse during hurricanes or earthquakes really break due to weakening by termites.
So, how are termites in houses detected?

1. Dumb Luck. Often termites are detected . . . .
- when the vacuum cleaner leaves a dent in the skirting board
- when someone makes a dent in the floor
- when the door falls off
- when termites fly (in huge numbers) inside the house
-
Termite mud spots when you notice strange bits of mud in the plasterwork
- when the light/fan in the toilet/laundry won't turn off
- when the wood in the window frames looks mottled through the varnish
- when you notice strange bubbles in the paint
- when you lie awake at night and wonder what those quiet noises might be
2. When Other Trades are . . . .
- repairing a springy floor
- fixing leaky plumbing
-
Living lawn mower working in the garden
- putting in new cupboards
- installing your home theatre
3. Regular Inspections . . . .
- when you look under the floor and see tell tale shelter tubes
- when you look near all the wet areas and notice bubbled or uneven surfaces
- when you crawl around in the roof space and the wood seems hollow
- when you look at all those wings you keep vacuuming away . .
- when you hire a competent someone to do the looking for you

Actions to stop or control termites need not be scary.
Termite control comes in four forms: cultural, physical, biological and chemical.
Well, at least those are the headings used in most text books.
Chemical control is the least desirable, but is sometimes the only option.

Cultural control relates to what we do and the way that we do it. It pays to avoid the simple traps that make things inviting for termites. In tropical North Queensland, where life is excellent for pest termites, the old traditional wooden housing style sits up very high. The tall stumps and metal termite caps (inverted pie plates) provide excellent protection against sneaky termites. They can still come in from the ground, but it is far from inviting and they have to build shelter tubes over the pie plates. Not a great option for them and one which makes them very easy to spot. If you follow the "guide to avoiding termite problems" you are instituting a cultural control by reducing the termites' chances of getting a foothold. Nomadism is another cultural technique--it sort of parallels with disposable coffee cups, only this way it's your home that is short-lived. Some speculative builders seem to prefer this approach. Beware the short warranty. Keeping a horde of animals to eat swarming termites has to be helpful. Geckoes on the walls will eat many termites. Ants are perhaps the best and most persistent predators, cleaning up the bulk of each alate flight. Even chickens will make short work of termites as they try to extend their shelter tubes.
Physical control separates the food from the termite. Strip shielding, pie plates, posts on stirrups, and physical barrier systems such as Granitgard and exposed slab edges are examples of physical controls. Termites can also be controlled by taking their environment beyond the normal limits that their bodies can take. To this end, both sustained heat (over about 45 degrees C for an hour or so) or sustained cold (subzero--it is the ice-crystals that kill) can been used. Some services also use microwave energy--waves cook things well inside a tightly shielded oven, but it is fairly difficult to control such energy in a structure, where reflection is hard to predict, so be careful out there! These methods are not always a DIY option. Other proposed physical controls include eletrocution (in timber and soil) and bizarre electronic and sound repellents. Be wary of techniques that appear dangerous or hard to believe. If scary sounds did repel termites, they probably wouldn't ever eat grade schools.
Biological control is practised for many other insect pests, but has had little success with termites. Well, little success in the commercial sense. As with the ants and geckoes mentioned above, many societies have used termites' natural enemies to keep them in check. Birds and ants can clean up an amazing quantity of termites. Business has tried nematodes and fungi. The nematodes are tiny worms which parasitise termites and the fungi are disease organisms, perhaps best thought of as terminal tinea. While these work extremely well in controlled laboratory experiments, they have yet to make a significant splash in the market. Still, we're all eagerly waiting and at the moment it looks like nematodes are slightly ahead of the fungi. Flies, beetles and killer viruses also kill termites, so who knows what will happen

Chemical control was once the sum total of pest controllers' responses to termite problems. Now the consequences of poisoning soils and surfaces are becoming apparent as the old termiticides are withdrawn and the newer ones come under increasing scrutiny. As most commonly practised, chemical control for termites involves either soil treatment to provide a barrier of toxic residues or (for drywoods) tenting of the structure and flooding it with toxic gas (some such fumigants may damage the ozone layer). To be effective, a chemical applied to form a toxic barrier in the soil must penetrate evenly and then bind securely to the soil particles. It has to be persistent. It must not break down through the action of normal soil microbes. Another way to use chemicals is (in much smaller doses) to apply them directly to the termites such as in the bait box technique, either as topical dust, or as bait toxicants. There is a world of difference between surrounding a structure with several kilos of toxin applied in hundreds of litres of emulsion and the at most, few grams of a slow-acting toxin which may be used in a baiting system (the bulk of which may be removed after control is achieved). Other than poisoning the soil and timber, chemicals are also used against drywood termites, but as a whole-structure fumigation or a spot treatment. Spot treatments are only for where you can be 100% sure that you can find and reach each and every drywood colony.
Integrated termite management is a fancy term for putting it all together. For integrated control, you must plan, act as required, monitor, adapt and review. Take the long-term view and you can save a lot of money. Particularly if you build well (with physical barriers) in the first place.
What to do first is usually straightforward. If you have drywood termites, the infestation is usually limited (sometimes to a single piece of furniture, sometimes to the whole house). For subterranean termites, management should first aim to either exclude the termites (such as by repairing a physical barrier) or kill off the offending colony. Colonies can most often be killed by nest destruction, nest poisoning, by baiting or by judicial use of a non-repellent termiticide into the soil where they are active. Repellent soil poisons are best (not used, or) saved for new construction when you can be sure of a complete barrier. In the ideal world, your pest management technician will do a full timber pest inspection of the building and grounds and present you with a written report and (separately) a management plan (hopefully with a range of options). Again, ideally, remedial soil poison barriers would not be used (i) unless necessary and (ii) until the offending colony had been controlled. Repairs (unless for safety) should not be made until the colony is controlled as early disturbance can make management difficult by breaking up or concealing the termite activity. If baiting or using a non-repellent termiticide for colony control, you want to keep them feeding at full tilt until they have consumed enough poison to kill the whole colony.
OK, so you've found termites. Here's a quick step guide of what to do.
- Don't spray anything. Spraying just makes the rest of them go to where they're hard to find.
- Don't disturb them. Often it is cheaper to control them if they are undisturbed.
- Don't panic. Termites tend to work slowly, so you usually have time to act before things get noticeably worse.
- Read through these FAQ files so you have a good background knowledge.
- Don't call the first company you find in the phone book. Take your time, find a good inspector get a written report, then work out what to do.
- Do fix up the things that attracted the termites in the first place.
- Do remember to have another inspection scheduled to make sure that things are really fixed.
- Do consider regular inspections so you can catch any new attacks early.
They don't, just the vast majority of them.
Termite scientists are a fairly conservative lot, and like patterns. Termes is a Latin word meaning wood worm. It is a widely followed convention that the genera of termites be given names with -termes at the end, but it isn't required by the rules of naming animals. Just makes things easier I guess. Some genera don't. This is because the taxonomist who authored them broke with convention. The best know of these is Zootermopsis, the dampwood termites of North America.
Termites belong to the Order Blattodea (Pronounced Blat-oh-dee-a) , which they share with the cockroaches and sit in the infraorder Isoptera (Pronounced Eye-sop-terra). The termites (before nucleic acids took over taxonomy) had their own full order, but were later found to sit within the spread of the cockroaches. That name came form the Greek, Iso meaning equal and pteron, meaning wing. The name referred to the wings of the reproductive caste, which isn't very helpful as most termites are plain workers that never get to grow wings. There are two pairs of wings, with the front pair the same size as the hind pair. The name termite comes from the Latin word termes meaning woodworm (which probably covered some beetle larvae as well). See also here.
- Description:
Termites are small, pale to whitish, soft-bodied social insects living in a nest or colony system. They all feed mostly on plant fibre (cellulose). The colony is divided into castes, which do different jobs and mostly also look different. The most numerous worker caste is relatively undifferentiated and performs much of the colony work, there is a specialised soldier caste with head and jaw structures differentiated with stronger features and often mouthparts more suited to defence than feeding. The reproductive caste, known as alates (winged ones) are produced when nymphs mature to develop wings and a generally darker colouring. Metamorphosis is gradual (there is no pupal stage)
- The head is rounded and eyes generally absent except in the reproductive caste (and rarely in soldiers), antennae are beaded ('moniliform') with more than ten obvious beads, wings are also absent except in reproductive caste. They all have strong chewing mouthparts and can broadly be separated by looking at the patterns of their tiny teeth (not like ours, more like saw teeth). The wings are deciduous, shed shortly after
nuptial flight through breakage at a suture near point of attachment (hence de-alate), leaving small scales which persist. Termites are weak fliers, flights occur only under favourable conditions: nearly still air, high humidity and with falling barometric pressure indicating a likelihood of following rain. No constriction of the abdomen (as in ants, bees and wasps). Here's a similar description at the University of Delaware
Termites also behave in ways that makes them easy to identify. For a start, nearly every type live completely in the dark (except when building or when the winged ones are flying), so you usually only see them when something is broken or open. Once exposed, they will try to follow their scent trails home. If these are broken they just wander around looking lost or squeeze into any gap they can find.
Most species of termites have what is called a soldier caste. These grow strong heads, often much darker than those of the other termites. Very often, these strong heads also have big jaws. If you can find some of these among you termites, it makes the job of identifying the species much easier. Soldiers may be rare, only a few percent of the population, so look carefully.
