How does Termidor® work?


Termidor® termiticide and insecticide controls Subterranean termites, including the extremely destructive Formosan Subterranean termites, Dampwood termites and Drywood termites. If there are no active termites in your home, Termidor® will help ensure there won't be any in the future.

A Pest Shield certified professional will apply a liquid dilution of Termidor® along the foundation walls of your home or business to create a continuous treatment zone. The application method is called "trenching" or "trenching and rodding", and may sometimes require drilling holes through slabs or other hard surfaces adjacent to the foundation of your structure for maximum protection. The certified Professional may also treat conducive or termite active areas from the interior of your home, depending on the extent of the termite infestation and damage. Depending on your situation, a minimally disruptive Termidor® treatment along the exterior perimeter (PerimeterPLUS™) of your structure may be all the protection needed.


Termidor® is an advanced undetectable liquid technology. That means termites cannot see, smell, taste, or avoid it. Instead, they contact, ingest and share Termidor, completely unaware that doing so inevitably will kill them.


When termites eat Termidor-treated material, they will die. But Termidor® doesn't stop there. It eliminates termites by contact as well. And since termites can't detect its presence, termites can directly ingest and contact Termidor as they go about their normal routines.


Whenever a termite ingests or touches Termidor®, it can become a "carrier", transferring Termidor® to other termites it contacts. These termites, in turn, can become secondary carriers, behaving normally while they transfer Termidor to other termites they contact—and so on within the colony. Because Termidor® is slow-acting, it gives individual termites ample time to transfer it to others in the population. This unique, spiraling process is called the "Transfer Effect", and its devastating results maximize the protection of your structure.
