My house was recently professioally treated for termites. The chemical used with Termidor 80. I have a small house but the treatment was completed over two days. The first day the holes were drilled through the porch and patio and a trench was dug. They came back the second day and completed the job while I was not home. It started raining either during the treatment or shortly after. Probably a half inch or more. The ground was already damp before the rain. Will the rain lower my protection. Should I ask for the trench treatment to be redone?
I wouldn't worry at all about it. Termidor stays put, for one thing. The house also protects its perimeter from the worst of the rain, except in unusual cases. We give multi-year warranties with Termidor, after only 1 treatment. Short of actual flooding, you wont have trouble with termidor leaching/moving.
