The Bite Shield™ Guardian Mosquito Trap from Koolatron helps protect your property from mosquitoes and other biting pests so you can enjoy the outdoors with your family. Female mosquitoes and other blood-seeking insects rely on various clues to track down humans including our body heat and the carbon dioxide (CO2) we breathe out. The Bite Shield™ Guardian Mosquito Trap converts propane into harmless odorless CO2 and emits a plume into the surrounding air to attract female mosquitoes from up to 40 ft away. Once in range they are either captured by the optional sticky paper or sucked into the trap by a powerful vacuum fan. The optional Octenol lure acts as an attractant increasing the effectiveness of the unit The Bite Shield™ Guardian is a long-term solution to managing the mosquito population on your property. With continuous use the trap will catch a steady number of egg-laying female mosquitoes each day to disrupt their breeding cycle and gradually reduce the overall local mosquito population so you can truly enjoy outdoor living!
