I have been over run by flies and mosquitoes lately! I spray and spray then I cough and cough. I purchased this Bug Zapper in hopes it would help part of the problem. It has helped tremendously. I sit it on my counter and I don't worry about pesty bugs anymore. Thumbs up to this one. I plan on purchasing at least two more for outdoor use. If you have bugs Zap them with this Bug Zapper!
