First up, the answer depends on what type of termites are creating the problem. If they are drywoods, then maybe knocking things down will kill them, but if these are subterranean termites then definitely not. Drywoods live in small colonies, usually in individual pieces of timber, so a thoughtful demolition may effectively remove active colonies. Subterraneans, don't, they like to spread out through the structure and will have paths to ground (for water).  They will just go to ground at the first vibrations and come back up later to resume the attack somewhere else.

In some parts of the world, particularly parts of Africa and Asia, termites will quickly attack and kill transplanted trees and plants.  They attack the roots.  In the past, some very heavy doses of scary pesticides have been used to help the plants get established.  The attacks seem to drop off once the plants have been in for a few months. Keeping the plants well-watered all the time can make a big difference as water-stressed plants are more readily attacked.

Yes.  "White ant" is another misnomer used to label termites.  They're not white (cream is as pale as they ever get) and they are very different to ants.  Ants belong with bees and wasps whereas termites are really social cockroaches (did you just shudder?).  Please don't say "white ant" unless you were born before 1950, have really bad eyesight or have to so as not to cause offence.
