Flowtron BK-40D 40W Outdoor Bug Zapper

The Flowtron BK-40D is an outdoor electric bug zapper that covers up to one acre of yard, patio or farm. It uses a 40-watt ultraviolet bulb plus an included octenol cartridge to draw in flies and biting mosquitoes, and a 5,600-volt grid kills them on contact. The non-clogging grid lets insects fall to the ground instead of collecting inside, and it uses no chemical sprays or pesticides. Flowtron recommends hanging it about 25 feet from where people gather, and the weatherproof polycarbonate housing is made to stay outside. Flowtron's product page says "WEATHERPROOF, UL CERTIFIED, EPA REGISTERED & MADE IN THE USA" and lists "Made in the USA" in the specs.
