O…M….G… I have been plagued with flies coming inside this season due to the early heat I supposed. I’ve never experienced such a fly problem in my life. I have tried every type of fly shatter imaginable, but they all break as I probably kill 100 flies per day which equates to 500 swats as I’m not very good at it. I also bought some of those sticky things to set on the counter and around the house to catch them and catch them they did, but didn’t put a dent into the problem. Then I received this little gem. I thought it wouldn’t work worth a flip as it is tiny and the suction didn’t seem all that much. I doubted it would catch as many flies as the stickie things, but I set it up because any fly it catches is one less I have to swat. The instructions say to NOT put it by a competing light source, but I did. I placed it right beside my little Aerogarden that sets on my counter. I placed it so the top of the fly catcher’s light would be about even with the light on the Aerogarden because I can’t live without my Aerogarden and that is where the majority of the flies congregate because of the light. It is also hanging close to the door and many flies that come in the door go straight to the fly catcher and get eaten immediately. It was stunning. The flies flying under my Aerogarden light just zipped right over to the flycatcher and got sucked in immediately. Just zip… zip… zip… and they were gone. Although I just saw it catch about 30 flies in a few minutes, I still had no expectations of it completely eliminating my fly problem. It’s been a week now and I have yet to have to swat a single fly. Flies do still fly into the RV we are living in for the summer, but after just a bit, they go to my Aerogarden and then they fairly quickly checkout the light on the bug catcher and ZIP! They’re gone. It also got rid of all the fruit flies that were coming up out of my sink drain. We’re having an insane mosquito season due to the extreme TX heat, but I haven’t had a single one come inside and bite me. I assume SOME have had to come inside when we go in and out of the door often. If so, the bug eater got them as nobody has been bitten inside the RV. We are in love with this little darling and ecstatic that we purchased it and ended our fly problem. I intended to buy more of them if it worked fairly well, but it has been unnecessary as this single one is getting them all. I highly recommend this baby if you have an RV. I assume it would work well in a home as well and intend to try it there when we return.
