Fourmilab is surrounded on three sides by farmland. In the summer, bugs are all over the place. Faced with this case, defence in depth is the only choice: window screens, bats, Odonata on the pond, fly strips on the home windows and swatters in every room, and as the final degree of terminal defence, excessive voltage bug zappers with ultraviolet fluorescent lures. These are usually not elegant units, however they get the job achieved. The principle could not be simpler-flying insects, whose compound eyes see lengthy-wave ultraviolet light that mammalian eyes do not, are attracted by the lure tube, which seems to emit a dim blue mild to people. To reach the light, they have to fly between wires electrified with between four and eight kilovolts which, when the insect completes the circuit, kill-a-bug. The only disadvantage (at the least if you are not a flying insect) is that they don't seem to final very long. After somewhat multiple summer, the bulb either starts to flash on and off like a strobe light or simply refuses to gentle at all.
