I read a ton of negative reviews about this bug zapper. How it killed everything else but mosquitoes, how it got clogged up, how expensive it is to replace the bulb, how many beneficial bugs get killed, and so forth. I live in Houston, which is swampy and humid and a perfect breeding ground for mosquitoes. I also live in the middle of the city and we have no use for bugs around here, even in a 30-mile radius it is all an urban area. So I figured I could zap at will. I always had a problem with mosquitoes on my back porch. In the summer they would swarm around my pets and make them miserable. We had citronella candles, we have multiple porch fans, but nothing seems to stop the bloodsuckers. I installed the Flowtron zapper on a wall bracket about 15-20 feet from the porch. It kills a decent amount of bugs. The dead bugs look mostly like mosquitoes. The bad reviews said these were not actually mosquitoes but some other species which just looked like mosquitoes. In any case, I notice a significant reduction of my mosquito problem. I would even claim that I may have solved my mosquito problem for the time being. I also noticed that the zapper killed some drywood termites, which I take a bonus.
