While this might seem counter intuitive at first glance, you need to stop using a bug zapper if you want to ditch those mosquitoes for good. Granted, the corpses of insect bodies stuck to the cage and littering the ground beneath it make it seem like the thing is doing a good job, but the truth is that in order to kill that many bugs, the light has to attract bugs. And it doesn’t kill as many insects as it attracts, so you’re basically turning on a giant bug beacon in your backyard.
