The Mosquito Suction Trap by Aspectek attracts and kills mosquitos and other flying insects including biting flies, stink bugs and small beetles. The Mosquito Suction Trap is engineered for ultimate mosquito protection. How It Works 1. An Ultraviolet bulb generates insect-attracting light that draws mosquitoes toward the trap. 2. the powerful yet whisper-quiet vacuum fan sucks insects into the retaining cage where they quickly dehydrate and die. 3. A unique twist-to-close feature guarantees any insects still alive in the retaining cage will not escape when the trap is turned off. 4. Closing the top shuts off trap and keeps any still-living mosquitoes or bugs inside. Convenient for travel, patios, kitchens and porches, the Mosquito Suction Trap can be hung just about anywhere for the ultimate protection from annoying mosquitoes, flies, and more.
