I called them because of the reviews listed here and the manual that came with my home inspection service recommended them. The home inspection booklet said that they guaranteed service within 24 hours. I called at 8 am on Friday morning and the receptionist wanted to give me a time on the following Monday afternoon. When I told her about the 24 hour service, she gave me a time on the afternoon of the following day (Saturday). Everything else was perfect. The operator arrived on time, explained the service extremely well, sprayed the nest (which promptly disappeared) and charged me an incredibly reasonable fee. Since the nest was just outside my front door, I was concerned that a child would come to the door and be stung. It was very important to have it eliminated as quickly as possible. I would definitely call these people again. Excellent service, top notch in every way.
