How long will the effects of the Termidor foam remains active if I inject the foam into the exterior walls?
I have the base boards removed and see the remnants of the subterianian termites. I plan on drilling holes into the drywall before I replace the base boards and have had a professional company treat the perimiter of my home with termidor. They explained to me that treating the perimiter of the house will also kill the ones that have already entered my home. I really don't belive that and haven't found that info anywhere on the internet.
Termidor Foam will remain active for about 6 weeks when injected into the walls. Termidor Sc placed in a barrier around a home will kill foraging termites as they return to the colony....if the colony is not under the home (in most cases the colony will be out in the yard so this method does usually work). It is recommended that if you know where the termites are active in the wall void that you treat the area with a product like the Termidor foam just in case the main colony is under the house.
