Given enough time, termites will eat your house hollow. The structurally stability of your supporting wall studs and joists can be compromised It may take 50 years or more for termites to eat a house, but left unchecked they eventually will. Your neighbors won’t be happy either, because termites from your house will infest theirs. In the short term, 10-20 years, termites can make the house shift and sag. Replacing termite damaged wood can be very expensive because with wood that is not exposed, like floor joists in a raised foundation house, or open rafters in a garage or attic, you have to tear out the drywall to replace damaged wood. Mudsills, windows, decks, areas around vents, and foundation piers are common areas where termites damage.
Drywood termites are eliminated by fumigation. Fumigation does not kill Subterranean termites because their colonies are underground, to exterminate subterranean termites you need to spray chemicals into the ground. Fumigation uses Vikane gas that is lethal to them. The fumigant has no odor, no color, and leaves no residue behind. Fumigation is very safe when you prepare for it properly. Since fumigation is a gas, it is only effective when the gas is in use. When the gas is gone there is no longer any residual affect. Termites can start to come back as soon as the tent is off, however it may be some time before they return, and once they are there another several years for a new colony to become mature. With Termites, it’s not a question of IF, it is a question of WHEN.
