Control Method of Subterranean Termites
Most subterranean termite control is done by applying either termiticides to the soil or termite monitoring bait stations in or around the structure. The goal is to establish a continuous insecticide barrier between the termite colony (usually in the soil) and wood in a building.
Sometimes, there may be a secondary termite colony above the soil (in the roof or other areas with a constant moisture supply) that requires additional treatment. The termite baits do not leave a residual chemical in the soil. However, they can reduce and may eliminate a termite colony.
While use of termite baits as method of controlling termites is very appealing because it does not require extensive site preparation such as drilling or trenching and extensive application of insecticide to the soil or structure, research is still ongoing to develop the most effective baits and delivery systems.
