New home buyers, in particular, should be wary of purchasing a home that has recently been spot-treated for termites. One company uses baits and one company uses liquid insecticides applied under my house. This is the most common question heard about termite control. Unfortunately there is no simple answer. Both techniques have their proponents.
Termite baits are a relatively new way to control termites.
Rather than acting as a barrier to prevent termites from entering your home, like conventional soil treatments, baits are designed to suppress or elimininate entire termite colonies. Baits incorporate a slow-acting toxicant or growth regulator with a suitable termite food. When discovered by foraging termites, the toxicants are delivered to the colony as part of the sharing of food by worker termites. These stations are inserted into the soil around an infested building. Three other bait products are also currently registered for termite control.
