This is a good old fashioned bug zapper that really gets the job done. I've searched for one of these for years in the store, but the alternatives that they stock these days all seem to be underpowered or too dim to attract insects. This one is bright and it packs a punch, vaporizing any mosquito, moth, or other insect annoyance instantly when it touches the wire cage inside. Installation is easy too - just find a spot (usually away from your deck or wherever people congregate), run a wire there, and plug it in.
