Subterranean termites are widespread throughout the United States. Because they are so abundant, prevention alone may not always protect a structure from infestation. If a structure has become infested, additional action must be taken. Over the past few years, the number of subterranean termite treatment methods has increased
Liquid Termiticide Applications
Liquid termiticides are usually applied completely around and underneath a structure covering all areas where termites might gain access. For an existing building, the perimeter of the foundation is trenched and drilled, then treated with termiticide. The goal of the treatment is to put a chemical blanket between the termites in the soil and the structure above. The chemical blanket can also affect those termites inside a building by preventing their successful return to the soil. In many case, these termites will die of dehydration.
Non-Repellent Termiticides
There are a few non-repellent termiticide treatments available on the commercial market. These chemicals are not repellant and termites cannot detect them in the soil. Therefore, the termites tunnel into the termiticide while foraging, contact the chemical, and die.
Termidor
Termidor is a non-repellent termiticide. The active ingredient is fipronil. Fipronil is unique in that it can be transferred from one termite to another through contact and trophallaxis (communal feeing). This allows it to affect more termites than those that contact the chemical directly. The advantage of this product is its long-term effectiveness in the soil. Test data indicate that fipronil may be effective longer after the initial application than other liquid termiticide products.
