We moved to a property on a river in norther Wisconsin in deep woods. Yeah, ka-zillions of every biting bug you can imagine all summer long. We lived last summer through the swatting,itching, and being held captive in the house after dusk. We decided this year that we had to do something different. We put up this unit the day it arrived. It is a mean killing machine. By morning, it is so full, the mosquitoes fly in to kill themselves on it, but there's no room. So every day I clean it off. Cleaning is so easy - 30 seconds with the blow dryer, done, and it's ready to zap those nasty devils again. We can sit outside a few feet away and there's an occasional biter, but this thing is a lifesaver. This one hangs by the garage in the front. I'm buying another for the back. Love, love, love this killing machine. We are sitting outdoors, enjoying summer s'mores. Life is good.
