ThermaCell® Mosquito Repellent.
ThermaCell Mosquito Repellent Appliances work by heating a mat saturated with a special ingredient from a flower those little winged pests hate!
As the mat is warmed, the skeeter-fighting ingredient is released in the air, offering up to 12-hour protection for approx. 15' in all directions! Measures 3 x 2 x 7 1/2"h., 8 ozs. each.
