Bite Shield Wall Mount Flying Insect and Mosquito Trap
The Bite Shield Wall Mount Flying Insect and Mosquito Trap attracts flies and mosquitoes as well as gnats or moths. Made by Lentek/Koolatron, this unit uses three devices to attract flying insects inside. The 4W UV black light bulb emits ultraviolet rays at the 365nm wavelength, which creates a photo catalytic reaction when it comes in contact with the Ti02 (Titanium Dioxide) coating inside the trap. Octenol is a proven attractant to blood-seeking flying insects: each Bite Shield™ Octenol cartridge lasts 45 to 60 days. Note: never use Octenol inside your home or business. Then a powerful fan draws the flying pests into the capture tray where they die and dehydrate. This unit does require 110VAC power. Hang it on a wall. Effective area is about 322 square feet.
