There are over 30 species of blood letting flies. These flies hunt by sight.
They are painful vicious biters of both people and horses. And they are more than just an
annoyance - they can transmit diseases like Equine Infectious Anemia (EIA) and Potomac Horse Fever
The horse & deer fly can suck blood for several minutes and only the female horse fly bites to feed on blood.
Both horse flies and deer flies will deposit eggs on vegetation around moist soil or very near water.
The larvae will burrow down into this soil and feed on organic matter. The larvae mature into flies in the late spring.
The adult flies are very strong fliers traveling long distances from breeding sites.
They will enter any area within minutes of spraying with insecticides.
Fly sprays are basically ineffective when it comes to horse flies. The best control is obtained by
trapping the female flies before they have the opportunity to bite/reproduce. This will reduce
the population and make the area around your barn and pasture a much more enjoyable place for both
you and your animals.

Epps Biting Fly Trap™
Reduce biting flies in your pasture by 80%…whether they are biting your horses, cows, dogs or kids, they deliver a very painful bite. The Epps Biting Fly Trap kills horse flies, deer flies, and all other biting flies. The Epps trap is uniquely effective because it traps biting flies by using the flies own natural behavior patterns. Many biting flies are attracted to large objects of contrasting color to the surroundings because such objects tend to be potential hosts like cattle, deer, and horses.
Also, biting flies tend to circle the host before actually landing to bite. The Epps Trap takes advantage of these behaviors by providing a large, contrasting surface area, with transparent areas (which are actually clear plastic deflectors) representing air space between an animal’s legs and over its back through which the flies would normally circle before feeding.
Flies see the deflectors as open spaces and try to fly through then. They hit the deflectors and ricochet into the soapy water in the trays below. Dish soap is added to the water in the trays to cause the flies to be wetted and drown faster. Studies have shown that the unit covers an average of 20 acres and 1 pound of biting flies each day, 24/7…
WOW! This is the ultimate biting fly trap, and you’ll wonder how you ever managed without it…The trap requires no chemicals, or messy baits, just add soapy water. This trap is environmentally sound… In the past, poisons have been used to control insects. However the use of poisons is not favored due to the deleterious effects on the environment, and the possibility of killing potentially beneficial insects. Contact Horseline Products 1-800-208-4846.
