Claim:
1. A method of protecting a building from damage, by termites, comprising the steps of:— (a) detecting the presence of termites within the building or a close vicinity thereof; (b) infusing a protected region of ground below the building with ozone by delivering ozone into said protected region to create a superatmospheric pressure field below the building, the delivery at a determined concentration which is less than that at which its presence would cause detrimental effects on humans occupying the building, and sufficient to cause the termites to vacate the protected region, (c) discontinuing delivery of ozone upon departure of the termites, thereafter maintaining ozone delivery turned off and allowing termites to return to the protected region, (d) recommencing delivery of ozone at said determined concentration after the termites have returned to the protected region and continuing delivery until the termites again vacate said protected region, (e) repeating said discontinuing and delivering steps for as long as the termites return into said protected region wherein the ozone concentration is varied below said safety threshold level thereof whereby to avoid habituation of said termites to its presence.
