Fly-killing device
A fly-killing device is used for pest control of flying insects, such as houseflies, wasps, moths, gnats, and mosquitos. Most such devices are lethal to insects, but some designs (such as certain bug vacuums) can be used for live capture and later release. == Flyswatter ==
A flyswatter (or fly swatter) usually consists of a small rectangular or round sheet (some across) of lightweight, flexible, vented material (usually thin metallic, rubber, or plastic mesh), attached to a lightweight wire or plastic handle about to long. The venting or perforations minimize the disruption of air currents, which can be detected by the fly and allow it to escape, and also reduce air resistance, making it easier to hit a fast-moving target such as a fly. A flyswatter is ideally lightweight and stiff, allowing quick acceleration to overcome the fast reaction time of the fly, while also minimizing damage caused by hitting other objects. The flyswatter usually works by mechanically crushing the fly against a hard surface, after the user has waited for the fly to land somewhere. However, some skilled users can injure or stun an airborne insect in mid-flight by whipping the swatter through the air at an extreme speed.
