Do outdoor patio lights attract mosquitoes and other bugs?

Mosquitoes are mainly attracted to the heat that is generated in lighting sources that produce Ultra Violet (UV) rays. So a regular light bulb in a patio light does attract pests. LED light bulbs do not give off ultra violet rays and do not emit a significant amount of heat. For this reason, mosquitoes will not generally swarm an LED light as there is nothing present to attract them to that particular light source
