A fly-killing machine is used for pest control of flying insects, akin to houseflies, wasps, moths, gnats, and mosquitoes. 10 cm (four in) across, connected to a handle about 30 to 60 cm (1 to 2 ft) lengthy fabricated from a lightweight material such as wire, wooden, plastic, or metallic. The venting or perforations decrease the disruption of air currents, which are detected by an insect and permit escape, and likewise reduces air resistance, making it simpler to hit a quick-shifting target. The flyswatter usually works by mechanically crushing the fly against a tough surface, after the person has waited for Zap Zone Defender the fly to land someplace. However, users also can injure or stun an airborne insect mid-flight by whipping the swatter by way of the air at an excessive speed. The abeyance of insects by use of quick horsetail staffs and fans is an ancient follow, courting again to the Egyptian pharaohs.

The earliest flyswatters were actually nothing more than some kind of putting floor attached to the end of an extended stick. An early patent on a industrial flyswatter was issued in 1900 to Robert R. Montgomery who called it a fly-killer. Montgomery sold his patent to John L. Bennett, a wealthy inventor Zap Zone Defender and industrialist who made further improvements on the design. The origin of the title "flyswatter" comes from Dr. Samuel Crumbine, a member of the Kansas board of health, who wanted to lift public awareness of the well being points brought on by flies. He was impressed by a chant at an area Topeka softball recreation: "swat the ball". In a health bulletin printed soon afterwards, he exhorted Kansans to "swat the fly". In response, a schoolteacher named Frank H. Rose created the "fly bat", a device consisting of a yardstick hooked up to a chunk of display screen, which Crumbine named "the flyswatter". The fly gun (or flygun), a derivative of the flyswatter, uses a spring-loaded plastic projectile to mechanically "swat" flies.

Mounted on the projectile is a perforated circular disk, which, according to advertising copy, "will not splat the fly". Several comparable merchandise are bought, Zap Zone Defender principally as toys or novelty gadgets, though some maintain their use as conventional 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 entice for flying insects. In the Far East, it is a big bottle of clear glass with a black steel top with a hole in the middle. An odorous bait, Zap Zone Defender equivalent to items of meat, is positioned in the bottom of the bottle. Flies enter the bottle looking for food and are then unable to flee as a result of their phototaxis conduct leads them wherever in the bottle besides to the darker top the place the entry hole is.

A European fly bottle is extra conical, with small toes that raise it to 1.25 cm (0.5 in), with a trough a few 2.5 cm (1 in) wide and deep that runs inside the bottle all around the central opening at the underside of the container. In use, the bottle is stood on a plate and some sugar is sprinkled on the plate to draw flies, who finally fly up into the bottle. The trough is stuffed with beer or vinegar, into which the flies fall and drown. Up to now, Zap Zone Defender the trough was generally full of a harmful mixture of milk, water, and arsenic or mercury chloride. Variants of those bottles are the agricultural fly traps used to struggle the Mediterranean fruit fly and the olive fly, which have been in use because the thirties. They're smaller, with out feet, and the glass is thicker for rough out of doors usage, pest control typically involving suspension in a tree or bush. Modern variations of this machine are often product of plastic, and can be purchased in some hardware stores.
