Recent Review: We back up to a drainage area and have horrific mosquitos. Called them on the weekend and they were out the following Tuesday. Right after they sprayed it rained. Still reduced the bugs significantly for a couple of days, then they were back. Called Joe's back and they said they had us "red-flagged" that they would probably have to come back due to the drainage ditch and the rain. They were out the next day for another treatment (no charge). The tech said it would take a couple of times to get ahead of them. They have been back twice since then and of course, it has rained both times, but it is amazing how well it works. I used to be the buffet line for them, but we were out all evening last night, right through dusk, and I didn't get bit once. I will definitely keep them coming back!
