I had a fly infestation in our house. After days of trying on my own, I called to get advice. I had overnight guests coming that day and they were willing to come that afternoon (within 2 hours of my call) to treat the house and find the source. The tech guy was thorough but didn't find the source. I was a bit discouraged and skeptical when he left. But within 12 hours, they were basically gone. Problem solved! I appreciate their quick response time, professional service via phone and in person. They only sprayed outside my house as I have young children and didn't want the chemicals where they play. But it seemed to do the job with just outside spray. Also I used the yelp deal to save a bit. I will call them again!
