A fly-killing system is used for pest control device control of flying insects, resembling houseflies, wasps, moths, gnats, and mosquitoes. 10 cm (4 in) throughout, attached to a handle about 30 to 60 cm (1 to 2 ft) long fabricated from a lightweight materials equivalent to wire, wood, plastic, or steel. The venting or perforations reduce the disruption of air currents, pest control device which are detected by an insect and allow escape, and likewise reduces air resistance, making it simpler to hit a fast-moving goal. The flyswatter often works by mechanically crushing the fly against a tough floor, after the person has waited for the fly to land somewhere. However, users also can injure or stun an airborne insect mid-flight by whipping the swatter through the air at an excessive pace. The abeyance of insects by use of brief horsetail staffs and fans is an ancient follow, courting again to the Egyptian pharaohs.

The earliest flyswatters were in truth nothing greater than some kind of placing floor attached to the end of an extended stick. An early patent on a business flyswatter was issued in 1900 to Robert R. Montgomery who referred to as it a fly-killer. Montgomery offered his patent to John L. Bennett, a rich 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, who needed to lift public consciousness of the health issues caused by flies. He was inspired by a chant at a local Topeka softball sport: "swat the ball". In a health bulletin printed 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 bit 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, based on advertising copy, "won't splat the fly". Several related merchandise are sold, pest control device mostly as toys or novelty gadgets, although some maintain their use as traditional fly swatters. Another gun-like design consists of a pair of mesh sheets spring loaded to "clap" collectively when a trigger is pulled, squashing the fly between them. In distinction to the traditional flyswatter, such a design can solely 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 hole in the center. An odorous bait, such as items of meat, is positioned in the underside of the bottle. Flies enter the bottle in the hunt for meals and are then unable to escape because their phototaxis behavior leads them wherever within the bottle except 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 couple of 2.5 cm (1 in) wide and 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 a few sugar is sprinkled on the plate to attract flies, who ultimately fly up into the bottle. The trough is crammed with beer or vinegar, cordless bug zapper for backyard zapper into which the flies fall and drown. Previously, the trough was typically stuffed with a harmful mixture of milk, water, and arsenic or mercury chloride. Variants of these bottles are the agricultural fly traps used to battle the Mediterranean fruit fly and pest control device the olive fly, pest control device which have been in use since the 1930s. They are smaller, without feet, and the glass is thicker for pest control device rough out of doors usage, often involving suspension in a tree or bush. Modern variations of this device are sometimes manufactured from plastic, and could be bought in some hardware shops.
