The insect killer circuit presented here is designed to attract insects during night, and electrocute them through a high voltage mesh trap. The unit can be installed in farms for protecting crops from potentially harmful insects. The unit being solar powered does not depend on human intervention and works independently.

Mosquito and other forms of fly trap mechanisms work by making use of luring techniques for attracting the insects, which involve carbon dioxide gas, body odor simulators and ultraviolet lights. These traps become very useful in areas which may be highly infested with mosquitoes, however due to its high costs such traps are not very commonly used everywhere.
