A fly-killing device is used for pest management of flying insects, akin to houseflies, wasps, moths, gnats, and insect zapper mosquitoes. 10 cm (four in) throughout, Zap Zone connected to a handle about 30 to 60 cm (1 to 2 ft) lengthy fabricated from a lightweight materials similar to wire, wood, plastic, insect zapper or metallic. The venting or perforations minimize the disruption of air currents, that are detected by an insect zapper and permit escape, Zap Zone Defender and insect zapper in addition reduces air resistance, making it simpler to hit a fast-moving goal. The flyswatter often works by mechanically crushing the fly towards a hard floor, after the person has waited for the fly to land somewhere. However, customers may injure or stun an airborne insect mid-flight by whipping the swatter by the air at an extreme pace. The abeyance of insects by use of quick horsetail staffs and followers is an ancient practice, relationship back to the Egyptian pharaohs.

The earliest flyswatters have been in fact nothing greater than some type of hanging floor Official Zap Zone Defender attached to the end of an extended stick. An early patent on a commercial flyswatter was issued in 1900 to Robert R. Montgomery who known as it a fly-killer. Montgomery sold his patent to John L. Bennett, a wealthy inventor and industrialist who made additional improvements on the design. The origin of the title "flyswatter" comes from Dr. Samuel Crumbine, a member of the Kansas board of well being, Zap Zone Defender USA who wished to boost public awareness of the health issues caused by flies. He was impressed by a chant at a local Topeka softball recreation: "swat the ball". In a well being bulletin printed soon afterwards, insect zapper 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 attached to a piece of screen, 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, "won't splat the fly". Several comparable products are sold, principally as toys or novelty gadgets, though 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, Zap Zone Defender squashing the fly between them. In distinction to the standard flyswatter, such a design can solely be used on an insect in mid-air. A fly bottle or glass flytrap is a passive trap for flying insects. Within the Far East, it is a big bottle of clear glass with a black metallic prime with a hole in the center. An odorous bait, corresponding to pieces of meat, is placed in the bottom of the bottle. Flies enter the bottle searching for food and are then unable to flee as a result of their phototaxis conduct leads them anyplace within the bottle besides to the darker prime the place the entry hole is.

A European fly bottle is more conical, with small ft that increase it to 1.25 cm (0.5 in), with a trough a few 2.5 cm (1 in) wide and deep that runs contained in the bottle all across the central opening at the bottom of the container. In use, the bottle is stood on a plate and a few sugar is sprinkled on the plate to draw flies, who eventually fly up into the bottle. The trough is filled with beer or vinegar, into which the flies fall and drown. In the past, the trough was generally filled with a harmful mixture of milk, water, and insect zapper arsenic or mercury chloride. Variants of those bottles are the agricultural fly traps used to fight the Mediterranean fruit fly and the olive fly, which have been in use because the nineteen thirties. They are smaller, with out toes, and the glass is thicker for rough outside usage, often involving suspension in a tree or bush. Modern variations of this system are often made from plastic, and could be bought in some hardware stores.
