The additional treatment, from my quarterly treatment, took care of the problem. I asked the technician to check out a carpenter bee on my deck since he was here, which he did, and found the little hole. However, he did not spray there and suggested I call the office about having an expensive treatment done. I called but cancelled it until I have more carpenter bees. I felt like he should have sprayed the hole because at one time during a regular treatment a couple years ago the technician took care of the same situation.
