This outdoor mosquito trap uses more traditional bug-catching technology to help with your insect issues. The Flowtron BK-40D Insect Killer looks like a hanging lantern that gives off a gentle UV blue light to draw mosquitoes in. Once they get too close, the device zaps them. After they’ve been fried, the bugs simply fall to the machine’s base, which you can empty as needed. The zapper is covered by a weatherproof polycarbonate roof and cage, so you can leave it outdoors with no issue. The grid also won’t clog if you don’t get around to emptying this regularly, minimizing maintenance on your end. Just keep in mind that this also comes with an octenol attractant, which is a chemical that draws in biting insects, that should be replaced every 30 days. But once this device is plugged in, it can provide bug-protection coverage of up to an acre.
