<p>Set up a no-fly zone in style with the Thermacell® Patio Shield Mosquito Repeller! It repels pesky mosquitos by creating a 15' zone of protection, making it ideal for patios, decks, pools, porches, campsites, and more. The synthetic allethrin formula is inspired by repellent extracts found in plants. There's no need for smoke, flames, citronella, DEET, spray, or on-skin chemicals. Just turn it on, and enjoy your time outdoors unbothered! Repellent mats (3 included) last up to 4 hours each, and they change color when it's time to refill. Heat-activated design requires no cords or batteries, and it is instead powered by a safe 12-hour fuel cartridge (included). Easy to refill.
