"I don't know what he did or how but all I know is new apartment I moved in is ROACH FREE!!! Mike's prices are beyond reasonable - I called a lot places and he had the best deal! In addition, I asked him about bedbugs as well and he answered my questions over the phone even before I even made the appointment. Today he came by because I had a concern about black stuff on my floor. He informed me it was tar coming from the roof - but he was nice enough to come check it out for me. Excellent customer service from a genuinely nice and KNOWLEGABLE person! I hope I don't need Harvey's Pest Control again but if I move somewhere else and I do, he will be the first person to call."
