We had someone come spray our new to us home and about a week and I saw a live carpet beetle in our kitchen. I know it takes time for the spray to work, I was told they have to come into contact with it. However, after a week and I am seeing on alive, that does not make me happy. I lose sleep over bugs and I expected to not see any. The man who came was very very nice and I would love to work with him again. It’s nothing against him. He was great.
