I live in the FL panhandle and mosquitoes are horrendous around here. I have resorted to everything, even buying one of the Solo 451 backpack foggers. Upon other reviews I decided to give this unit a try. I use bug zappers in my garden to take care of corn earworms and other pests that derive from moths but the ones I have used in the past (Stinger) were jokes and hardly lasted a season. I put up two of these Flowtron units and was working in the barn after the sun went down and I noticed I could hear this light zapping sound coming from the garden. It wasn't loud enough to be moths so I went out to investigate. I found a cloud of mosquitoes swarming around the Flowtron and so many were diving into the light and getting burned to a crisp that is literally smelled like burning hair. We must have taken out tens of thousands of the pest that first night alone. I have already ordered replacement octenol lures and plan on doing what others have suggested and put out a new one every two weeks. I am very pleased and have already suggested these units to neighbors. Buy with confidence.
