I just have a crawl space which is a poured concrete footer and concreate block which he inspected yesterday. He looked at the foundation and the base plates and said there was no indication of termites at all. We purchased the house approximately 11 years ago and the previous owners daughter told us her parents had the house treated sometime before we purchased it but I am not certain how long before we bought it that the treatment was completed. There are several places in the garage and driveway next to the house where holes were drilled which I assume was to pump the treatment around the foundation and then plugged.I am not sold on the science of termidor like it is stated (BUT, I have not kept up on any formula changes like I used to.). It usually comes with a higher cost but if you can get some for home use, it may assist you in having a better peace of mind. Go with your feelings in this situation. At least it seems you have a good diagnosis of the issue.
Preface: I haven't went into the type of home you have, below ground finished areas, type of foundation, proximity of any well or cisterns....(I have just been basic) if you respond with more specific's I can get more specific.
After doing some research it seems that the Termidor can take up to 90 days to kill the colony and I wasn't sure if a faster treatment would be better. By the way I appreciate your help.
