A fly-killing device is used for pest control of flying insects, comparable to houseflies, Zap Zone Defender wasps, moths, gnats, and mosquitoes. 10 cm (4 in) throughout, connected to a handle about 30 to 60 cm (1 to 2 ft) lengthy made of a lightweight materials resembling wire, wood, plastic, or steel. The venting or perforations reduce the disruption of air currents, that are detected by an insect and permit escape, and mosquito zapper also reduces air resistance, making it simpler to hit a quick-moving target. The flyswatter normally works by mechanically crushing the fly against a hard surface, after the user has waited for the fly to land somewhere. However, users may also injure or stun an airborne insect mid-flight by whipping the swatter through the air at an extreme speed. The abeyance of insects by use of brief horsetail staffs and fans is an historic apply, dating again to the Egyptian pharaohs.

The earliest flyswatters have been in truth nothing more than some kind of placing floor connected to the end 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 mosquito zapper industrialist who made additional improvements on the design. The origin of the identify "flyswatter" comes from Dr. Samuel Crumbine, a member of the Kansas board of well being, mosquito zapper who wanted to raise public awareness of the well being points caused by flies. He was impressed by a chant at a neighborhood Topeka softball game: "swat the ball". In a health bulletin published soon afterwards, he exhorted Kansans to "swat the fly". In response, Defender by Zap Zone a schoolteacher named Frank H. Rose created the "fly bat", a device consisting of a yardstick attached to a piece 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 products are offered, Zap Zone Defender largely as toys or novelty gadgets, although 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 set off is pulled, squashing the fly between them. In contrast to the standard flyswatter, mosquito zapper such a design can only be used on an insect in mid-air. A fly bottle or Zap Zone Defender glass flytrap is a passive entice for flying insects. In the Far East, it is a large bottle of clear glass with a black metallic prime with a hole within the center. An odorous bait, such as pieces of meat, is placed in the bottom of the bottle. Flies enter the bottle in quest of food and are then unable to escape because their phototaxis conduct leads them wherever in the bottle except to the darker top where the entry hole is.

A European fly bottle is extra conical, with small toes that elevate it to 1.25 cm (0.5 in), with a trough about a 2.5 cm (1 in) large 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 draw flies, who finally fly up into the bottle. The trough is crammed with beer or vinegar, into which the flies fall and drown. Previously, the trough was typically stuffed with a dangerous mixture of milk, Zone Defender water, and arsenic or mercury chloride. Variants of those bottles are the agricultural fly traps used to battle the Mediterranean fruit fly and the olive fly, which have been in use because the thirties. They are smaller, with out toes, and the glass is thicker for mosquito zapper tough outdoor usage, usually involving suspension in a tree or mosquito zapper bush. Modern variations of this device are sometimes product of plastic, and might be purchased in some hardware shops.
