How effective are bug zappers?
Regardless of the brand name or type of light, bug zappers do not reduce the number of mosquito bites you will get. Studies have shown that although mosquitoes are killed by the devices, their light attract more mosquitoes into the area than would be there without the devices, just like a porch light. Yes, they kill mosquitoes but they also kill beneficial insects like dragonflies. Thus, they are not recommended. If you already own a bug zapper and want to use it just to get the satisfaction of hearing the “zap”, then place it where it will attract mosquitoes away from the area you want to protect.
