Fourmilab is surrounded on three sides by farmland. In the summer season, bugs are everywhere. Faced with this situation, defence in depth is the one possibility: window screens, bats, Odonata on the pond, fly strips on the home windows and swatters in every room, and because the final level of terminal defence, high voltage indoor bug zapper zappers with ultraviolet fluorescent lures. These are not elegant gadgets, but they get the job performed. The principle couldn't be simpler-flying insects, whose compound eyes see lengthy-wave ultraviolet light that mammalian eyes do not, are attracted by the lure tube, which appears to emit a dim blue gentle to humans. To reach the light, they need to fly between wires electrified with between 4 and 8 kilovolts which, when the insect completes the circuit, kill-a-bug. The one disadvantage (at the least if you are not a flying insect) is that they do not appear to final very lengthy. After a bit a couple of summer season, the bulb either begins to flash on and off like a strobe light or simply refuses to light at all.
