How to treat the active termites inside the house that is in an exterior walls?

I found termites inside my house by the windows at my exterior wall there are insulation in the wall. How do I tread the termites that is in the wall, and how much do I need for a 10X10 room?


You will need to determine what kind of termite you have for us to direct you on the best treatment method. If you have drywood termites, you could drill holes into the galleries and inject a product like Termidor Foam to expand and eliminate the colony. You will only be injecting the foam into the studs and around where the activity is, not filling the entire wall void. It would be hard to determine exactly how many cans you would need withouth knowing where you are primarily seeing activity. If you have subterranean termites, you will need to do a trench treatment around the home to eliminate the colony in the ground with a product like Termidor SC. Termidor SC will last in the soil for at least 10 years to both eliminate your current termites and prevent any new ones from entering the home. The Termidor SC trench treatment would kill the existing termites in the wall of your home as well, but you could always do a spot treatment with the Termidor Foam to help speed up the process along with the trench treament. You can see how a homeowner can treat there home for subterranean termites in our article "How To Do A Termite Treatment". There are many variables that go into treating your home for termites so it may be easier to call our customer service staff at 1-866-581-7378 for better instruction to meet the needs of you and your home.
