Thermacell Mosquito Repeller Unit — Black

The Thermacell Mosquito Repeller effectively repels mosquitoes, black flies, and other biting insects by creating a 21 m² zone of protection for around 4 hours of bug-free comfort. Ideal for use in the garden, at the campsite or on the boat, the unit works by applying heat to a Thermacell Mat impregnated — not sprayed — with a synthetic mosquito repellent. The concentration of repellent in each mat is small, each contains 0.45g. Thermacell is approved by EPA & APVMA, and safe when used as directed. You need to use it away from uncovered food and avoid directly inhaling the vapour from the device. The active ingredient, D-cis/Trans Allethrin, is toxic to bees, cats and fish, therefore it's essential to avoid exposure to them. Allethrin naturally occurs in chrysanthemum flowers (similar to pyrethrin).
