When grilling, camping, on vacation, by the lake, on the farm, or while fishing, this electric fly swatter is your best friend. It operates with two AA batteries and generates an electric voltage of 1200 to 1500 V in the metal grid. The fly swatter works with a current strength that is safe for humans, which is sufficient to instantly eliminate flies and mosquitoes. You can either continue to catch mosquitoes resting on a surface or intercept them in the air with targeted swats.
