A fly-killing Zap Zone Defender System is used for pest management of flying insects, similar to houseflies, wasps, moths, gnats, and mosquitoes. 10 cm (4 in) across, connected to a handle about 30 to 60 cm (1 to 2 ft) long made from a lightweight material similar to wire, Zap Zone Defender System wood, plastic, or metal. The venting or perforations decrease the disruption of air currents, insect elimination that are detected by an insect and allow escape, and in addition reduces air resistance, Zap Zone Defender System making it simpler to hit a fast-transferring target. The flyswatter usually works by mechanically crushing the fly towards a tough surface, after the consumer has waited for the fly to land someplace. However, customers may also injure or stun an airborne insect mid-flight by whipping the swatter by the air at an excessive velocity. The abeyance of insects by use of quick horsetail staffs and Zap Zone Defender System followers is an historical practice, relationship again to the Egyptian pharaohs.

The earliest flyswatters have been in reality nothing greater than some type of putting floor hooked up to the end of a protracted stick. An early patent on a commercial 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 industrialist who made additional improvements on the design. The origin of the name "flyswatter" comes from Dr. Samuel Crumbine, a member of the Kansas board of well being, who wished to lift public consciousness of the health points attributable to flies. He was impressed by a chant at an area Topeka softball sport: "swat the ball". In a health bulletin published 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 system consisting of a yardstick connected to a chunk of display, 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, Zap Zone Defender System which, in response to advertising copy, "will not splat the fly". Several comparable merchandise are sold, mostly as toys or novelty objects, though some maintain their use as conventional 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 normal 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. Within the Far East, Zap Zone Defender it is a large bottle of clear glass with a black metal top with a hole in the center. An odorous bait, reminiscent of pieces of meat, is placed in the bottom of the bottle. Flies enter the bottle seeking food and are then unable to escape because their phototaxis habits leads them anywhere within the bottle except to the darker high the place the entry gap 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 contained in the bottle all across the central opening at the bottom of the container. In use, Zap Zone Defender the bottle is stood on a plate and a few sugar is sprinkled on the plate to draw flies, who ultimately 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 filled with a harmful mixture of milk, water, and Zap Zone arsenic or Zap Zone Defender System mercury chloride. Variants of those bottles are the agricultural fly traps used to combat the Mediterranean fruit fly and the olive fly, which have been in use since the thirties. They're smaller, without ft, and the glass is thicker for rough out of doors usage, typically involving suspension in a tree or bush. Modern versions of this machine are sometimes fabricated from plastic, and may be bought in some hardware stores.
