How will I know if the Termidor has worked after I applied it to a trench around my house? I want to know if there are active termites inside my home (under my floorboards is where they were before this).
Termidor SC starts to work within a few days of termites contacting a treated area but if you suspect an active infestation you will need to search and locate exactly where in the home they are infesting and spot treat the gallery directly. Otherwise there is no real way to know if the Termidor in a trench is working. Trenching is only part of protection and treatment for subterranean termites but if you are dealing with drywood, it would not have any effect on the termites since they would never have gone through the treated soil.
