No messy wax. No smelly sprays or greasy lotions. Thermacell® Mosquito Repellent Lantern works by heating an insert saturated with a special non-toxic ingredient, extracted from a flowering plant that the little buggers hate... it offers a "bubble" of biting-bug-free bliss for a radius of 15' all around! Its ambient light and decorative design perfectly adorn your deck or patio. Ideal for use while you are gardening, camping, or hanging around the backyard, Thermacell Lanterns have been evaluated by the EPA for safety and effectiveness. It works with all Thermacell repellent mats and refills and includes one Thermacell Outdoor Lantern, three Original repeller mats and one butane cartridge.
