There are a number of termite control products on the market today. The most effective and well-researched products are termiticides, which come in liquid and gas form. Termiticides also come in both repellent and non-repellent forms, with non-repellent forms being the more technologically advanced treatment approach offering a greater transfer rate to nestmates.
In conjunction with monitoring stations, bait devices continue to be an effective technique for identifying and treating active infestations. Unless combined with a preventive soil treatment, bait stations only provide protection against active infestations (they do not prevent future infestations). Bait devices have been very successful as part of Operation Full Stop, a government-funded program in New Orleans to research methods to control Formosan termites.
Pesticides that target termites are called “termiticides.” They are applied to the soil or directly to wood to control a termite colony.
A liquid termite treatment can be applied to the soil to target subterranean termites, or directly to infested wood to target small infestations of subterranean or drywood termites. Liquid or foam termite treatments also can be applied to the foundation of homes to help prevent termites from entering any cracks in the foundation.
A fumigant termite treatment is a termiticide in gas form, and it is used to target large, difficult to locate or inaccessible infestations of drywood termites. Fumigation is typically a last resort treatment after more targeted approaches have proven ineffective or the infestation has grown too large for targeted treatment.
Some termiticides come in powder form. Small amounts of dust can be injected into wood that houses termites to control the colony effectively.
Monitoring and bait devices are an effective means of controlling subterranean termite colonies. They are frequently used in conjunction with termiticide treatments, when the termiticide is applied first and then monitoring stations are set up to check for continued or future activity. Monitoring stations serve a preventative function and can be used even when there is no sign of termite activity. Once activity is confirmed, the monitoring stations are replaced with bait devices that contain termiticides that can control the colony.
Additionally, bait devices can be used when it is not feasible to apply liquid soil treatments. For example, bait devices can be used near wells and water sources where it is not advisable to treat soil with insecticides.
