We were somewhat skeptical about killing termites with an over the counter product because this is a job that is always left to the professionals, but we kept an open mind. After researching into Termidor and finding out that they are a professional company with a lot of high-quality products we decided to give the termite foam a shot.
This is the stuff the professionals use themselves, and it worked quickly and easily. The nozzle on the aerosol can fit right into the hole we drilled, and there was no escape from there. After a few days, we noticed there were no pellets or soot around our deck anymore.
This spray is very harsh and has a strong odor, but it is meant to get the job done. We do not recommend using this product indoors unless you are spraying it directly into the walls and nothing will be seeping out because the odor is pretty intense.
One of the best things about this spray is the residual effect that it has on the colony. Spraying the foam into the hole is a great way to ensure that you will not deal with an infestation anywhere near it.
