Professional exterminators get asked this question all the time. How fast can termites damage my home? And there is really no easy or accurate answer. It a FACT that termites do more damage to homes than fires, floods, windstorms combined. But they don’t destroy a house overnight. Nowhere near that. But, given enough time, they will do major serious damage to a home. Depending on the size of the termite colony, serious and costly damage may occur in a period of months or it may take several years. But one thing is for sure…termites work 24 hours a day, 7 days a week. They are eating away day and night non-stop. The best way for you, the homeowner, to prevent termites from damaging your home is to have a proper termite treatment in the soil around your home and to have it inspected at least once a year by a licensed professional termite expert.
