About Electric Bug Zappers
Now, you have a wonderful weapon against mosquitoes and other harmful insects that keep bugging you. A bug zapper is an electrical device that can injure or kill bugs through the use of electric current or radiation. It looks like a portable air-conditioner or ventilation system, with ultra-violet bulb. It emits UV rays to attract insects in. The insects get sucked inside through a powerful fan and then get killed through electrocution. However, there are similar devices that merely trap insects, not kill them intentionally. Trapped insects die due to dehydration or starvation. However, the compartment may be opened to release harmless insects like butterflies.
For the environmental-conscious individual, a bug zapper or trap can be an ideal solution because it does not use chemicals and efficiently utilises energy.
