I have been enchanted with the electrical zapper to find termites. It was wonderful the first time you came out for an area inside my house.
When I called for a new spot to be treated in a doorway leading outside, I was very disappointed that the technician did not even have it in his truck. I asked him after her treated the area with a liquid if he could come back and make sure we got all of them in the vicinity. He stated he would return in a few days and I have not heard from him yet. I am disappointed as your spot treatments are expensive....thus far hopefully effective.
