David came on time as promised. He is very professional and knowledgible, and a pleasant person. He was happy to answer and explain all the questions I had on all the insect-related issues. After completing the service, he wrote down in the invoice what I should do next, along with whatever recomendations he had. The cost (i.e., $140) is after 10% discount for Angie's List members. For me, it seemed a little expensive based on the time he spent at my house, which, I think, was about 30-40 min. I think, his rate is based not on the amount of time, but on the service/procedures involved. In my case, the situation was not too bad, so, he did not have to spend that much time. Anyway, overall, I'm very satisfied with David's service. I trust him, and will call him again if I have any issues with insects.
