Mosquito Magnet designs and makes carbon dioxide-based traps that attract, capture and kill mosquitoes and other biting insects for homes, businesses and outdoor properties. For more than 15 years, the brand has built its products around patented CounterFlow technology, which combines carbon dioxide, heat, moisture and attractant before vacuuming insects into a net. It introduced the first propane-powered mosquito trap for consumers and supports its traps through certified service centers and a one-year limited warranty.
