A fly-killing machine is used for pest control of flying insects, reminiscent of houseflies, ZapZone Defender wasps, moths, gnats, and mosquitoes. 10 cm (4 in) across, attached to a handle about 30 to 60 cm (1 to 2 ft) lengthy fabricated from a lightweight materials akin to wire, wood, plastic, or metallic. The venting or ZapZone Defender perforations reduce the disruption of air currents, which are detected by an insect and allow escape, and likewise reduces air resistance, making it simpler to hit a quick-shifting target. The flyswatter often works by mechanically crushing the fly in opposition to a tough floor, after the person has waited for the fly to land someplace. However, customers may injure or stun an airborne insect mid-flight by whipping the swatter by way of the air at an extreme speed. The abeyance of insects by use of short horsetail staffs and fans is an historic follow, dating again to the Egyptian pharaohs.

The earliest flyswatters have been actually nothing more than some kind of striking surface hooked up to the top of a long stick. An early patent on a business flyswatter was issued in 1900 to Robert R. Montgomery who called it a fly-killer. Montgomery bought his patent to John L. Bennett, a wealthy inventor and industrialist who made further improvements on the design. The origin of the name "flyswatter" comes from Dr. Samuel Crumbine, a member of the Kansas board of well being, who needed to raise public consciousness of the well being points caused by flies. He was inspired by a chant at a neighborhood Topeka softball game: "swat the ball". In a well being bulletin revealed quickly afterwards, he exhorted Kansans to "swat the fly". In response, a schoolteacher named Frank H. Rose created the "fly bat", a gadget consisting of a yardstick hooked up to a chunk of display, which Crumbine named "the flyswatter". The fly gun (or flygun), a derivative of the flyswatter, makes use of a spring-loaded plastic projectile to mechanically "swat" flies.

Mounted on the projectile is a perforated circular disk, which, in accordance with advertising copy, "will not splat the fly". Several similar products are sold, largely as toys or novelty items, although some maintain their use as traditional fly swatters. Another gun-like design consists of a pair of mesh sheets spring loaded to "clap" together when a trigger is pulled, squashing the fly between them. In contrast to the normal flyswatter, such a design can only be used on an insect in mid-air. A fly bottle or glass flytrap is a passive lure for flying insects. In the Far East, it is a large bottle of clear glass with a black metallic top with a gap in the middle. An odorous bait, resembling items of meat, is positioned in the bottom of the bottle. Flies enter the bottle in search of meals and are then unable to flee because their phototaxis behavior leads them anyplace within the bottle besides to the darker top where the entry gap is.

A European fly bottle is more conical, with small toes that elevate it to 1.25 cm (0.5 in), with a trough a couple of 2.5 cm (1 in) vast and ZapZone Defender deep that runs contained in the bottle all around the central opening at the underside of the container. In use, the bottle is stood on a plate and Zap Zone Defender some sugar is sprinkled on the plate to draw flies, who eventually fly up into the bottle. The trough is crammed with beer or vinegar, into which the flies fall and drown. In the past, the trough was generally filled with a dangerous mixture of milk, water, and arsenic or mercury chloride. Variants of these bottles are the agricultural fly traps used to combat the Mediterranean fruit fly and the olive fly, which have been in use for Zap Zone Defender the reason that 1930s. They're smaller, without ft, and the glass is thicker for tough outside usage, usually involving suspension in a tree or bush. Modern variations of this device are sometimes manufactured from plastic, and might be bought in some hardware stores.
