Anywhwere you live with bugs, buy these. Works amazing. Buy the bug attract for extra emphasis. The bug attract has stayed on. Both came in perfect condition. I have one in front and one out back. Run them all night. Yes I have a significant cut in flies, mosquitos and blood suckers since these came in. At night I hear it frying things, sometimes for several seconds. I don't even want to know whats so big it takes that long to electrocute. Fields of dead bugs? Havent noticed any. Bugs clogging the screen? Nope! Maybe im paranoid about the initial bug population but yes this will put a big dent in the insect population.
