Mosquito trap lights attract most insects to the device.
The built-in suction fan is strong enough to ingest flying insects and cause them to starve or dehydrate. You can purchase a super sticky glue board and put it into the mosquitoes storage plate to make sure mosquitoes don't escape.
You can also turn on the smart mode by press AUTO Switch. It stops working during the daytime and automatically starts working at night. (Of course, the premise is dark conditions)
