Terminix said that they would retreat the area of my front porch and have a contrator out to open the wall and determine what repairs are needed. Today the re-treatment was done with Termidor. However, I am still waiting to hear from the Terminix contractor on when they can come out. I am worried that if it takes too long for the contractor to check things out, the re-treatment will have killed any active termites in the wall and Terminix will try to say that all the damage is old and refuse to do repairs. The Terminix manager said not to worry that the chemical takes 60 – 90 days to kill all of the termites. Does this sound accurate? How long can I expect termites to remain active in the house after Termidor treatment?
