The principle of the mosquito trap is similar to that of the electric mosquito swatter. The mosquito trap uses the nocturnal, phototaxis and carbon dioxide adhesion properties of mosquitoes to attract mosquitoes through the lamp tube. Most of the mosquitoes in contact with the mosquitoes are instantly scorched by the external high-voltage electric shock net. In recent years, products developed through fans generate a powerful cyclone to suck mosquitoes into the bottom insect-collecting net, and trap them in the net until they air dry, so as to achieve the mosquito-killing effect.
