The Flowtron BK-40D covers a full acre with its 40W UV light, and the included octenol cartridge draws in mosquitoes more effectively than UV alone. The weatherproof polycarbonate housing holds up against rain and sun, and the 5600V grid reliably eliminates insects that come near.
This zapper is best for owners of one-acre yards who want a weather-resistant killer and don't mind some ongoing maintenance and audible operation.
Bottom line: Covers a full acre with UV and octenol, but the bulb replacement and zapping noise make it better suited for robust outdoor areas than quiet patios.
