Mosquitoes? Not today. Thermacell creates an invisible 20-foot shield — no smells, smoke, or flame. Runs for 9 hours on a battery, powers on with one press, and delivers full protection in just 15 minutes. Comes with a 12-hour cartridge, and refills swap out in seconds. Perfect for patios, cabins, and backyards. Repels both regular mosquitoes and virus-carrying ones — they won’t come near.
