I've read reviews on the bug zappers that say the lights do not attract moqsuitos and they therefore zap very few of them, and that the attractants that are supposed to be used in conjucntion with the zappers actually repel some species of mosquitos, including the one that seems so prevalent here. I've also read reviews that say they've zapped beaucoups skeeters, so who knows. I know my wife finally relented and said "Go spray whatever you want, just kill the damn things!" So I got the garden sprayer out night before last and mixed up a batch of pesticide and sprayed all the flower beds, the woods around the perimeter of the yard, under the deck and with what remained, I sprayed the yard itself until I ran out. I hate to do it in a way because when I do we don't see as many dragon flies and toads, but somethings gotta give. This morning my wife was outside on the deck watering plants and exercising and when she came in she said it was the first time in over a month she'd been able to enjoy being out on the deck first thing in the AM.
