A fly-killing system is used for pest control of flying insects, such as houseflies, wasps, Zap Zone Defender moths, gnats, and mosquitoes. 10 cm (four in) throughout, attached to a handle about 30 to 60 cm (1 to 2 ft) lengthy product of a lightweight materials equivalent to wire, wooden, plastic, or steel. The venting or perforations decrease the disruption of air currents, that 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 towards a hard surface, after the person has waited for the fly to land someplace. However, users can also injure or stun an airborne insect mid-flight by whipping the swatter by means of the air at an extreme pace. The abeyance of insects by use of short horsetail staffs and followers is an historical practice, dating again to the Egyptian pharaohs.

The earliest flyswatters were in fact nothing more than some type of hanging floor connected to the top 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 bought his patent to John L. Bennett, a wealthy inventor and chemical-free bug control 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 health, who needed to lift public awareness of the well being points caused by flies. He was impressed by a chant at a local Topeka softball game: "swat the ball". In a well being bulletin revealed soon afterwards, he exhorted Kansans to "swat the fly". In response, a schoolteacher named Frank H. Rose created the "fly bat", Zap Zone Defender a device consisting of a yardstick connected to a piece 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, Zap Zone Defender based on advertising copy, "will not splat the fly". Several comparable products are bought, mostly as toys or novelty objects, 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 contrast 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's a big bottle of clear glass with a black metallic high with a hole within the center. An odorous bait, akin to items of meat, is positioned in the bottom of the bottle. Flies enter the bottle in search of food and are then unable to flee as a result of their phototaxis behavior leads them wherever in the bottle besides to the darker top where 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 about a 2.5 cm (1 in) huge 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 a few sugar is sprinkled on the plate to attract flies, who eventually fly up into the bottle. The trough is full of beer or vinegar, into which the flies fall and drown. Prior to now, the trough was sometimes stuffed with a harmful mixture of milk, water, and Zap Zone Defender arsenic or mercury chloride. Variants of those bottles are the agricultural fly traps used to battle the Mediterranean fruit fly and the olive fly, Zap Zone Defender which have been in use because the thirties. They are smaller, without feet, and the glass is thicker for Zap Zone Defender tough outdoor Zap Zone Defender utilization, typically involving suspension in a tree or bush. Modern versions of this gadget are sometimes manufactured from plastic, and might be purchased in some hardware stores.
