Caution: Pesticides are poisonous. Photo by Department of Entomology, University of Nebraska-Lincoln, House flies are generally larger than stable flies and do not have forward-projecting mouthparts. Cost: Varies by manufacturer and model. And unlike mosquitoes, the bite of a horse fly is very painful. For example, simply spraying insecticides may not work if you are not targeting the right species, and may also kill beneficial insects and contribute to the development of insecticide resistance in many pest flies. Lesser house flies are similar in appearance to the common house fly but smaller and duller. Rotate that choice with another that is in a different IRAC group which may have a different mode of action. It contains Prallethrin, permethrin, Piperonyl Butoxide and Citronella. Implement prevention, management, and control methods. as few as 50 stable flies or 100 horn flies. Photo by Erika Machtinger, Stable fly adults are typically slightly smaller than house flies, although size can be misleading. If identification of immature filth flies is necessary, sample specimens can be collected in isopropyl alcohol and sent to extension educators for identification. At rest, house flies hold their body parallel to the surface and have downward-facing mouthparts. They are charcoal gray in color, with 2 dark stripes on the thorax, and a few diffuse spots on the top of the abdomen. However, the pupae are calcified (hardened), which makes using biological control with parasitoids inadequate for control of this species as the parasitoids cannot penetrate the calcified pupal case. However, most often a horn fly will not have to fly more than three miles to find a host. However, they will also feed on horses. Pyrethrins are compounds that have natural insecticide properties extracted from the flowers of some chrysanthemum species. Horn Flies overwinter as puparia (in the cocoon) beneath cow pats and emerge the next spring as adults. Probably not! Regardless, at this point the plan can be revised as necessary. Review your monitoring records and see if there is a downward trend. Flies can hatch in less than 12 hours after eggs are laid in the right conditions. Stable flies can lay several clutches of 60 to 130 eggs. Horn Flies. In general, jug traps catching over 250 flies per week or spot card counts over 100 are indicative of high levels of fly activity. Fly pressure may: Behaviors like constant stomping and movement and reduced grazing can have serious effects on the performance of pastured and show horses and may cause long- or short-term injury or losses of condition. To reduce risk of resistance the best option is to create an IPM plan as proposed by this guide and, if using chemical control methods, by rotating chemical classes. This requires frequent turning and covering to maintain a high internal temperature that will kill developing flies. Spot cards are 3-to-5-inch white index cards that are placed on rafters, eaves, or building supports where flies like to rest. Unlike face flies, house flies can be seen on all parts of the animal body. This is in contrast to house flies, which hold their bodies parallel to the surface and have downward-facing mouthparts. Be sure to fully read and understand pesticide labels and Safety Data Sheets before applying any pest control product on the farm. These may be levels implemented by the farm owner or clients that worry about animal health. On equine farms, tolerance to certain pests may also vary by whether they are a human or animal health hazard (low tolerance) or merely a nuisance (high tolerance). The eggs hatch and the tiny larvae consume the developing flies, effectively killing them. During hot and sunny weather, they may move downward onto the animal’s belly. Fecal and other pathogenic bacteria, such as, Cause pain and irritation, and cause pest avoidance responses including tail swishing, head and neck movements, and twitching, Lead to changes in grazing behavior like reduced grazing time and lower forage intake, Reduce energy available for growth, reproduction, and body condition maintenance, Increase blood cortisol concentrations, heart and respiration rates, and rectal temperatures, Cause eye and skin disorders, including allergic dermatitis, The options available for that particular pest, How you can interrupt the pest's life cycle with the respective control options. Since baits are toxic, it will be necessary to prevent other animals and children from being exposed to them. Following label directions for application rates, the products should be applied to target areas and then brushed lightly in the direction of the hair. Face flies resemble house flies, and distinguishing between the two can be difficult. Answer: Integrated pest management (IPM) is the use of multiple methods to maximize pest control while minimizing cost and risks to humans, animals, and the environment. On cooler days, they may also feed on the neck, shoulders and back. Horn flies differ from stable flies in development substrate as well as other body features. Several species of fly pests are common on equine facilities that are not discussed in this guide. Males spend much of their time in flight and have a characteristic hovering and circling pattern.
