Horse flies (insect family Tabanidae) are probably the most severe fly pests of cattle on Missouri pasture and range (Figures 1 and 2). Figure 2Tabanus atratus is one of the most easily recognized and notorious horse flies in eastern North America.
Because most horse flies are day-feeders, it is theoretically possible to protect Missouri cattle, horses and people from attack by staying inside during daylight hours.
After installing the horizontal chute boards, set another post and install boards to make a protective rail (R). The treadle sprayer, properly constructed, installed and filled with an appropriate insecticide, will reduce the number of horse flies biting pastured cattle.
The trap consists of four panels made from plastic sheeting, plastic screening or mosquito netting.
Once the trap is in operation, movement and heat radiating from the black-painted beach ball seem to attract female horse flies. This large, bluish-black fly with black wings can exceed 1 inch in length and inflict a very painful bite. Because this is not practical for pastured beef cattle, producers need information on control techniques that will reduce horse fly biting rates on their livestock. Almost 50 years ago, MU entomologists Curtis Wingo and Stirling Kyd described an economical cattle self-spraying approach that produced effective horse fly control.
The pump device, copper or plastic tubing, nozzles, springs and other hardware are available from most farm supply or other stores dealing in sprayer parts.
In the late 1970s, MU Extension entomologist Jim Huggans tested an umbrella-type horse fly trap under Missouri pasture and range conditions and demonstrated that it could provide measurable control for a few cattle or horses.
This cone is most effectively constructed of transparent material, such as a plastic drinking cup, with the bottom cut out.


Well-traveled cattle paths, natural fly-ways through woods or brush, and livestock watering or feeding areas have been productive sites. A small piece of insecticide-impregnated resin can be placed into the capture jar to kill the flies rapidly, but they will die in a day or so during midsummer. The pump assembly includes a bracket for holding a plastic or metal container (H), which holds about a gallon of the insecticide concentrate. The sprayer will also control horn flies and face flies, so it is not necessary to use additional treatments against these pests.
The base plate can be made from an 8-inch square of plywood; the jar lid is screwed or nailed to it, and a hole is cut through the base plate and lid. Livestock will be curious to inspect the trap and will destroy it if they are not excluded by fencing. Field trials have indicated that it usually requires several such traps surrounding a pasture to afford measurable reduction in the horse fly population. Horse flies are adept at locating warm-blooded animals; cattle, horses and similar large creatures are favored hosts.
However, field trials have demonstrated that daily treatment of cattle with synergized pyrethrins (a natural insecticide extracted from plants of the genus Chrysanthemum) will reduce biting rates by horse flies without adversely affecting cattle. In recent years, cattle sprayers using battery or solar power have been marketed, but these all incorporate mineral or similar bait and do not exploit forced-use placement.
A grommet or ring may be attached to each lower corner to attach guy lines that hold the trap up. The inverted cone is then glued in place inside the jar lid, and the jar is screwed upside down into its lid.
They usually continue crawling upward and eventually progress through the hole in the plywood base, through the inverted funnel and into the plastic jar where they cannot escape and return to the host animals.


Therefore, trapping horse flies may be best suited to protecting a few horses or show cattle confined to small lots or pastures. Generally, this has been feasible only for dairy cattle (and for horses) because of their high management level. If you plan to treat horses, be sure that you use a formulation labeled specifically for them. The top half of this frame should be covered with plastic screen or heavy-gauge clear plastic sheeting, stapled to the periphery of the base plate and then wired or otherwise affixed to the heavy wire passing through the legs of the tripod.
A trapping program can remove enough female flies from an area to decrease the horse fly biting rate. In some cases, it is possible to install the trap on a productive site just outside the cattle or horse pastures. The female fly uses her sharp mouthparts to slash a wound in the host's skin and then laps up the blood that results. Few producers are capable of, or willing to, round up beef herds every day, and even if this could be accomplished, the disruption of grazing might actually result in a greater economic loss than that caused by horse flies. This produces pain and annoyance to the host, plus economically significant blood loss when horse fly populations are large and their feeding pressure is severe. Horse flies have been implicated in transmission of cattle anaplasmosis and other blood-borne diseases in livestock. Clothesline or other cord may be attached to rubber or plastic balls by using any of several glue-type products sold to make repairs on the soles of athletic shoes.
