Bug zappers are one of the most popular bug control devices ever. Walk around any suburban neighborhood in the evening, and you'll hear the pop and sizzle of insects being electrocuted. It must be working, right?
Less than 1% of the insects killed by bug zappers are biting insects.

Sure, the bug zapper is killing insects by the dozens. The problem is, it's not killing the right bugs. Less than 1% of dead bugs lying in the bottom of bug zappers are biting insects, like mosquitoes. Most of the insects fried in these devices are doing us no harm whatsoever, and may even be beneficial. Night-flying moths are attracted to the light of the bug zapper because they navigate by the light of the moon. Beetles, too, tend to fly kamikaze missions.
Research shows that bug zappers make no measurable difference in mosquito populations in your backyard. Save your money for mosquito controls that work.
