Not sure why I didn't switch to your company sooner. My girl and me threw hundreds of dollars away with another pest control company for excuses with no results. We literally got blamed by the other spray company for everything under the sun rather than getting the drain fly problem fixed. They blamed it on our trash, dishes in the sink and we literally keep a clean house. The first time your guy came out he looked around, went outside shined a light under the house brought us outside and showed us millions of drain fly's from a broken waste pipe we had under the house. Not once did the other company who I wont call out take the time to even think about anything like that. We since got the pipe repaired and had a few treatments and not one of those flies are in our house now. Imperial pest prevention is absolutely wonderful. You guys have a customer for life!
