Do Bug Zappers Work? Q. I believed I read somewhere that bug zappers don’t actually work. My neighbor’s zapper is driving me loopy with that ZZZZT noise all night. I’d like to show him proof that all he’s doing is annoying his neighbor. A. Yes, there is some scientific information on the usefulness of bug zappers, but first we'd like to distinguish between the bug zappers that homeowners use of their yards to (hopefully) kill mosquitoes, and the industrial insect mild traps that pest control professionals use mostly in restaurants, meals plants, and warehouses. These expensive commercial traps are used primarily to kill house flies and they do work. The relatively inexpensive backyard bug zappers kill loads of flying insects, just not mosquitoes. Bug zappers use ultraviolet light to attract mosquitoes to a metal grid the place they are electrocuted or "zapped." Folks that personal these traps swear by them. They point to the piles of dead insects that they empty out of the trap each morning. And people insects do seem like mosquitoes. But mostly they are midges, harmless fliers that do not chunk and are thought of helpful. Bug zappers truly attract and kill only a few mosquitoes. Instead, the ultraviolet mild attracts hordes of insects into the yard that wouldn’t have been there in any other case. Yard zappers have by no means fared very effectively in research tests. One research found that 89% of the zapped insects have been midges; only 3% have been female mosquitoes capable of biting. The remainder were aquatic insects, predators, and insect parasites. In one other research, after eleven days of continuous operation, the zappers failed to cut back the mosquito biting charge within the check yards.
