Always refer to the insecticide labels for current and specific instructions for use and application. The table below is not a comprehensive list, nor does it suggest a recommendation. Sawdust has been shown to support fewer developing flies in some studies. Is your tolerance level close to zero (left)? Photo by Hafiz Issadeen on Licensed under CC B Y 2.0, Larvae are cream to yellow with a tapered end and a blunt end and pupae are reddish brown and oval in shape. Horn flies develop exclusively in fresh cattle manure, whereas stable flies prefer decaying organic matter that is slightly older and from various sources. But with the overwhelming number of products available, how can you determine which one to use? Preferred material, and likely the only material, for face fly egg-laying is fresh cattle manure, which makes face flies a primary concern in mixed-use facilities (those with horses and cattle) or at horse farms that are near cattle facilities. Face Flies superficially look like House Flies but they lay their eggs only on fresh cattle manure in fields. The purpose of evaluation is to determine if: The key to both monitoring and evaluation is record keeping. Every horse at a property must be fed these feed-throughs to prevent flies from developing in all other suitable manure. Other sanitation practices can reduce the likelihood of fly development or limit nutritional resources for adult flies. Adult lesser house flies are similar in appearance to the common house fly but smaller and with three stripes on the thorax that are less pronounced. The entire life cycle is completed within 2-4 weeks. Horn Fly adults typically occur on pastured cattle but they may also attack sheep, goats, horses, mules and dogs on any farm. As flies rest on these surfaces, they leave fecal and/or regurgitation spots that can be counted. This major pest of cattle is found in most cattle-producing areas of the world. Horn flies are accidental pests of horses in that they can feed from horses but cannot complete their development in horse manure or horse-associated substrates. Photo by Janet Graham on Licensed under CC B Y 2.0, Lesser house fly larvae are hairy and very distinct from the smooth appearance of other filth flies. However, there are more risks associated with fly populations than just nuisance problems. Many of the methods used for controlling house flies can be used for lesser house fly if they become a nuisance. 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. Both face flies and horn flies are best monitored on the animal by either fly counts or evasive behaviors, as previously mentioned for stable flies. In fact, some of these flies, like the black soldier fly, are actually beneficial in reducing pest fly numbers. House fly pupae are oval, red to red-brown, and look like rodent droppings. To reduce the risk of resistance it is important to not expose multiple generations of a pest population to the same insecticide mode of action. But stable flies are aggressive biters that feed on the horse’s legs and lower body. Habronema or Summer Sores For monitoring purposes, leave traps out for a day and then count the captured flies. Selection and percent of active ingredient is another consideration for chemical control of filth flies. While stable fly traps are somewhat more difficult to use, they are more reliable because they allow you to accurately identify the species of fly. A female horn fly can lay up to 100 to 200 eggs during her life of approximately six to seven days. During hot and sunny weather, they may move downward onto the animal’s belly. anisopliae and Beauveria bassiana. It is better to look for a checkerboard pattern on the abdomen, a tan spot on the thorax behind the eyes, and posture. 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. Hence, Horn Flies (Face Flies too) are more a pest of pastured cattle, but they can move to confined animals if the pastured cows are moved close in. Protect Your Animals with Bye Bye Insects, Based on your zip code and the number of animals you have, we can generate an accurate and effective Fly Predator schedule tailored just for you. Flies can transmit pathogens that cause disease or other conditions in horses; for example: Flies also have a negative impact on horse condition and physiology. From time to time, horse owners have assumed that these ear ta… Second, while insecticides may reduce adult flies that come into contact with the compound, they do not address the source of fly development. Filth fly problems generally occur from spring through fall, with peak populations occurring in July and August, depending on local climate and weather patterns. Fly Predators will help control but must be released near breeding manure, Use 50% more Fly Predators per cow than for confined animals, Requires undisturbed cow pat to reproduce. Horn Flies congregate on the back, and if hot or raining, on the belly. This is not a suitable control method for horn flies or face flies that develop exclusively in cattle manure. Insecticide repellents are effective. Stable flies hold their body at an angle to the surface on which they are resting. If a horse has thin skin or is sensitive they can react to the pain of the bite itself with a jump or bolt forward and can also have a skin reaction swelling in the area of the bite. Development from egg to adult is about two weeks in warmer weather. However, they will also feed on horses. Stable flies can be distinguished from house flies at rest by body posture. Question: Why should I learn to identify the pests and their life cycles? Parasitic wasps are very small biological control agents of house and stable flies. 1. These same attractants can also be used in homemade traps. Posture is another way to recognize different species. In addition, proper ventilation, like the addition of outdoor-rated fans, can aid in quick drying of bedding and stored manure. Adult house flies are non-biting flies with sponging mouthparts. Many fly eggs can hatch in as little as 12 hours, so proper removal and storage can limit pest problems. Males spend much of their time in flight and have a characteristic hovering and circling pattern. These tiny flies are most active at dawn and dusk. The insecticide is transferred onto the back and flanks through natural grooming behaviour as a result of the fat solubility of the insecticide and its ability to migrate through the lanolin in the hair. Horse flies attack large mammals, such as humans, dogs, and, of course, horses. During warmer days in the early spring, some Face Flies may come out of their hiding places in the attic and walls and appear on south-facing windows. Simply covering manure (with a secured tarp or similar material) can exclude adult flies and keep them from laying eggs. "Cowboy" music, poetry, horse tips and much more! Photo by Dr. Lantz S. Crawley, Starbar BiteFree Trap. They can be distinguished from rodent droppings primarily by shape, with fly pupae being rounded and not tapered at the ends. If you are around horses or a stable lately, you may notice an increase in flies such as stable flies, house flies, horn flies, and horse flies. The flies spend most of their life on the host animal, usually congregating on the back and shoulders. Horn flies are persistent, tiny grey flies that feed on large mammals such as cattle, bison, buffalo, and horses. The most important areas to cover are material being added to the pile and material that is up to seven days old. If high levels of these flies are present and causing nuisance problems, it is best to locate where these flies are developing and remove the source. Depending on the season, these flying insects can make a horse's life miserable as they bite, suck blood, and feed on secretions around the eyes and other tender parts of the horse's body and limbs. Integrated pest management may, but doesn't necessarily have to, involve multiple strategies to control flies. Horn flies often cause problems for horses that are pastured with or near cattle. Image by Erika Machtinger. Fly Predators will help control Horn Flies but the Fly Predators have to be distributed in the pastures where the undisturbed cow pats occur and at 1.5x the normal application rate per animal. 3. Regardless, at this point the plan can be revised as necessary. Face Flies are strong, robust fliers that can travel several miles. This requires frequent turning and covering to maintain a high internal temperature that will kill developing flies. Because stable flies are sensitive to hot summer temperatures, seasonal activity differs by environmental conditions and region of the country. It contains Prallethrin, permethrin, Piperonyl Butoxide and Citronella. Watch for fly location on the animal body, coloration, and mouthparts. Farms can be spotless, perfectly managed, and still have pest problems. This open-access article highlights the use of parasitoids on equine facilities. Horn flies resemble stable flies but are smaller, narrower, and have shorter mouthparts. These may or may not be effective depending on local resistance and application. This can also prevent adult flies from laying eggs. The larvae go through three stages, getting slightly bigger at each stage. Research shows that only about 5% of house fly and stable fly populations will reside on the horses themselves. Piperonyl butoxide is another compound often found with pyrethrins. These can be effective when competing food sources are limited. The larvae develop within the dung and pupate in the surrounding soil. First, decide on the type and application method: residual insecticides, fly baits, larvicides, on-animal fly sprays/roll-ons/wipes, or feed-through growth regulators. Photo by JacLou DL. These may be levels implemented by the farm owner or clients that worry about animal health. While identifying some species is easier than others, it may be necessary to employ a few monitoring methods to see what flies you actually have before you can learn more about their biology and decide on control methods.

These fly pests are similar in size, shape, and color, and develop in similar habitats containing fresh or decomposing organic matter. Horn flies are small flies, about 1/4 inch long, that spend essen-tially their entire adult life on the animal hosts. The base of the abdomen also has a distinct yellow patch on either side. Please note that this is not a suitable control method for horn flies or face flies that develop exclusively in cattle manure. They are charcoal gray in color, with 2 dark stripes on the thorax, and a few diffuse spots on the top of the abdomen. Mechanical methods can be used to modify manure management. Manure can also be actively composted. So providing a shady area for animals during the day can provide some relief. The key is to take counts consistently—at the same time of day, on the same animal, in the same location on the farm, and in frequent (e.g., weekly) intervals. The wasps attack and kill the pupal stage of developing filth flies, primarily house flies and stable flies. © Spalding Laboratories. Also like jug traps, sticky ribbons have the added benefit of capturing small numbers of flies. House flies are found near the eyes, nose, or wounds, and have downward-facing mouthparts. Unlike the House Fly, Face Flies are pests of cattle in pastures during the warm months. However, they may not kill the insect pests, just repel them. They are a nuisance for livestock, horse flies (particularly female ones) land on the body of cattle and bite them to draw their blood. Adults have four black stripes behind the head and a yellow abdomen. If you see horses constantly stomping, you probably have stable flies. Photo by Erika Machtinger. Remember the keys: consistency and recordkeeping. Black flies, deer and horse flies, biting midges, and mosquitoes are all common biting flies. While these flies are common, they do not develop in the same materials as filth flies, and an IPM plan for filth flies will not affect these populations. Horn Flies overwinter as puparia (in the cocoon) beneath cow pats and emerge the next spring as adults. Also included in this group are automatic fly sprayer systems. Once the larvae pupate, adult female wasps will lay an egg that develops within the fly pupae, killing the fly. Fly screens on windows in barn areas can reduce fly presence in the stable areas. House flies have mostly gray bodies with yellowish abdomens, four black stripes on the thorax (the area of the fly directly behind the head), and are about ⅜ inch in length. Photo by Erika Machtinger, Flies can develop quickly in waste hay and manure. Photo by Erika Machtinger. Females require blood meals for egg production and can lay several hundred eggs during their lifespan. These can be used when the area cannot be cleaned as frequently as necessary to break the fly life cycle. Total development time from egg to adult depends on environmental conditions, the most important of which is temperature. Parasites that use flies as intermediary transportation to their horse hosts include the skin-aggravating Habronema and Onchocerca and the eye-invading Thelazia species. Female face flies preferentially feed on the mucosa associated with the eyes and nose, so they are often found on the face. They’re most attracted to moving objects and dark objects. Probably not! Automatic fly misting systems are a type of residual and premise spray. Perhaps you misidentified your pest or maybe your monitoring method isn't sufficient. Spreading the manureis the best solution, breaking up and drying out the flies' home will decrease their presence. Horn flies rest on a cow between feedings; stable flies remain on … In typical farming situations, this is the economic threshold—the point where the cost of damage created by the pest(s) exceeds the cost of control. Bothersome insects can cause the animal to become nervous and interrupt its performance. They are charcoal gray in color, with 2 dark stripes on the thorax, and a few diffuse spots on the top of the abdomen. In some cases, a certain number of pests can be tolerated. Caution must be taken to protect animals and water sources during application. Photo by Janet Graham on Licensed under CC B Y 2.0. So providing a shady area for animals during the day can provide some relief. Photo by Seymours images. Photo by Department of Entomology, University of Nebraska-Lincoln. They key is complete coverage of areas where pests have been observed. Basic water management can reduce many natural sources of water. However, targeted control options are available for each of these fly pests and life stages, with the goal being to break (or interrupt) the life cycle at one or more points and reduce pest numbers. These typically provide knockdown benefits (i.e., they knock the pest off the animal). Because of these risk factors, it is important to consider developing an IPM plan for fly control. Stable flies are biting flies with long, pointed mouthparts that can cause pain when biting. They’re also attracted to carbon dioxide. House flies can fly several miles to find suitable areas for development. The increased stress load can quickly compromise the health of an animal. If fly development is identified in an area that can be easily managed (e.g., a manure pile), a single strategy to eliminate or move the manure pile or exclude flies from the pile may be enough. Moisture is naturally present in animal waste as well, which allows it to be a suitable site of development for many filth flies. Photo by Erika Machtinger. Adult flies can travel several miles while searching for new hosts. It is important to identify whether flies are developing on the farm or adults are flying in from neighboring facilities. Question: What does “integrated pest management" mean? Large numbers of flies (more than 200 per animal) cause lower weight gains and milk yields. Fly sheets, masks, and boots can be used to keep fly pests from accessing the face, legs, or body of horses. The feeding of large numbers, as shown above, can cause lower weight gain and reduced milk production. These insects are blood-feeders whose frequent, painful bites lead to infections such as mastitis (inflammation of the mammary glands), and conjunctivitis (pink eye) in their hosts. Identifying house fly adults is the key to management. It is important to understand and follow the regulations concerning manure and nutrient management in your state. Photo by Erika Machtinger, Stable fly adults are typically slightly smaller than house flies, although size can be misleading. Face Flies are now resistant to many pesticides, Consult your local Veterinarian or farm extension agent for effective control methods in your area, Note: not all flies on the face of your animals may be Face Flies. Younger larvae are found slightly deeper in the material in which they are developing, and older larvae move closer to the surface as they find dryer areas in which to become pupae. Sticky traps can be purchased or made at home, and hung in areas where flies congregate, like feed rooms. Spot cards are 3-to-5-inch white index cards that are placed on rafters, eaves, or building supports where flies like to rest. However, horn flies are smaller, have shorter mouthparts, and are typically found on the body of the animal, whereas stable flies are often found on the legs. Quick knockdown and long-lasting protection against a wide array of insects, including stable flies, house flies, bot flies, horse flies, horn flies, face flies, ticks, deer flies, mosquitoes, fleas, gnats and lice. They spend much of their time resting on branches and fences and attempting to catch and copulate with female flies as they move about. Sticky traps, such as the Starbar Bite-Free Trap or the BugJammer Knight Stick, can be used to both monitor and control stable flies. The feeding behavior of the face fly can help distinguish it from other flies. The larvae are off-white or cream in color, have a tapered appearance on one end, and are rounded on the other end. Photo by Erika Machtinger. House flies and stable flies can find habitat suitable for development on equine farms. Both sexes bite intermittently and may feed up to 20-40 times per day. The time required for the horn fly to complete its life cycle is between 10 and 20 days, depending on the temperature and time of year. These flies apparently migrate extensively and will go to and stay on horses. Adult management is required. They only work on flies that lay eggs in manure, such as houseflies, horn flies and stable flies. During warmer days in the early spring, some Face Flies may come out of their hiding places in the attic and walls and appear on south-facing. These flies often develop in trash, carrion, or other decaying matter, but typically do not cause animal or human disturbance. Photo by Erika Machtinger. Handle pesticides carefully and store them in their original labeled containers out of the reach of children, pets, and other animals. The life cycle takes about 2 weeks. For cattle, very small amounts of active ingredient (less than 2 g) are released onto the animal in a season. A wise horse owner makes use of many tools, not only to keep the biting insect … Best for: Horses living in close proximity with cattle or other livestock that attract horn and face flies; horses boarded at a facility without a broad fly-control program. Keeping feed storage areas clean, removing spilled feed quickly, and covering feed in bins will eliminate many sugar resources. Be aware of the external parasite species that are in … Manure management eliminates sites that are suitable for fly development. This is in contrast to house flies, which hold their bodies parallel to the surface and have downward-facing mouthparts. Cross-resistance is when developed resistance to one toxin leads to resistance of a similar toxin because of how these toxins act on the pest, or the mode of action. Monitoring should be established before pests become a problem, but it can be started at any point. The keys to cultural control, or sanitation, are moisture and manure management. Face flies resemble house flies, and distinguishing between the two can be difficult. Both sexes are blood feeders, taking 20 or more blood meals each day with their stiff needle-like mouthparts. Photo by Jina Lee. Horn Fly adults typically occur on pastured cattle but they may also attack sheep, goats, horses, mules and dogs on any farm. Implement prevention, management, and control methods. Horn flies have been implemented as a developmental vector (carrier) for Stephanofilaria stilesi, a spirurid nematode that causes stephanofilariasis in cattle. Get notified when we have news, courses, or events of interest to you. Larvae of the lesser house fly have a “hairy" appearance compared to the smooth larvae of other filth flies. Watch for fly location on the animal body, coloration, and mouthparts (stable flies are typically on the legs of the animal and have forward-projecting mouthparts). Photo by Wolfgang van de Rydt, Spot cards are an odor-free way to monitor for flies. This spreading allows the manure to dry fast enough to support little or no fly development. In addition, only apply products that are labeled for use in the state of application. Horses are accidental hosts; horn flies may be found as adults, but they are not developing on your farm unless you also have cattle. Unlike house flies, face flies are rarely found in barns or other buildings, but they can enter buildings during the fall as they seek shelter in which to overwinter. Horse flies are one of the most ferocious breed of flies. Infection did not occur in 2 calves inoculated daily for 5 days with mouthparts from 50 horn Dispose of empty containers right away, in a safe manner and place. A good rule of thumb for spreading is one horse's manure for every fi… It is important to note that baits will attract and kill house flies but not other blood-feeding flies. Proper farm and facility drainage should be established, and leaky waterers, hoses, or other water sources should be repaired quickly. Horn flies (Haematobia irritans) are a common pest of cattle in Europe, North Africa, Asia Minor, and the Americas. Adult Horn Flies are slender, 3/16” long and are about 1/2 the size of a typical House Fly. Usually, once you start noticing high numbers of adult pests, it is too late to do much to quickly solve the problem. Therefore, it is unrealistic to have a tolerance threshold of zero. Check with local county or state regulations before using any product. Answer: You need to monitor pest numbers to establish whether pest numbers are increasing or your control methods are working in an objective way.
