Most species of termites have soldiers.  This is a special caste within the colony that takes on certain roles. Soldiers tend to have large heads.  It is very common for their mandibles to be greatly enlarged.

1. Sort of nutty, especially if fried.  You might need to try more than one . . .
2. They have taste receptors a bit like us and like us, they get a lot of their taste sensation from what they can sniff. (Don't believe me?  Blindfold a volunteer.  Hold a freshly cut slice of apple under the nose.  They'll happily munch a piece of raw potato thinking it to be apple)

A competent inspector should know enough to understand that there is almost always a small possibility that an inspection could, no matter how thorough or competently done, miss some termites.

There are several reasons for this:

No.  In general termites prefer timber that is a bit soft, decayed or weathered but they will eat many types of hardwood (wood from trees with flowers not cones).  There are also many types of tree that produce timber which is generally termite resistant and quite a few of these trees are hardwoods.

Here's some pointers to get you started.

You can do things that reduce the amount of water getting in to the soil near your perimeter walls:

1. Make sure that rainwater on the roof does not drain into the soil.
2. Grade the soil around the house so that water drains away, not towards the walls
3. Don't have gardens, ponds, sprinklers, ferneries or pools near walls.
4. Make sure that overflow drains from hot water services and air conditioners don't soak into the soil near the wall.

You can do things to help the water get away: 

This will depend on the size and complexity of the structure, the location and the type of inspection required.  Say you are getting a typical house checked out before you buy it.  I would normally expect that to take around two to three hours for the pre-purchase inspection.  Obviously, an old or heavily renovated house will take more effort than a brand new one.  If you have a contracted service or have a barrier system installed (subterreanean termites), then the regular inspection can be a lot faster, maybe even 45 minutes to one hour.  If you have reported an i
