- Description: The Horse Bot Fly is found all throughout the world and is the primary species of bot fly in North America. This particular fly goes through three metamorphoses during a life cycle. A new generation of bot flies is produced every year. The Horse Bot Fly is famous for its larvae that is internally parasitic to mammals. You probably know of them by the tiny yellow eggs (nits) that the adult bot fly attaches to your horse’s inner leg and belly. The female bot fly can attach between 200 and 1,000 eggs to a horse over the course of summer. These disgusting parasites may be ingested when the horse licks the area where the nits are located. Once they are ingested, they continue to mature into bots (maggots) and attach themselves to the walls of the stomach. It is critical to be prompt in treating horses suffering from bots before the burrowing causes irritation and infection in the host's mouth and stomach. Severe infestations may lead to problems with the gastrointestinal tract, as well as anemia.
- Control Product: It is important to control bot flies with a product like ProZap DyFly. To eliminate stomach bots treat your horse with Jeffers® Ivermectin, while also using a bot knife for the careful removal of the bot fly eggs.

Horse Fly
- Description: The horse fly is one of the largest true flies, in some cases measuring over an inch in size (similar to the size of a bumble bee). The horse fly is easily identified by its dark grey body and large green-metallic eyes. The horse fly can also be spotted by the dark black markings on its transparent wings. Horse flies are very strong fliers, persistent in attacking livestock and equine with a severe bite. The horse fly can afflict immediate pain to you and your animals with their gruesome bloodsucking habits.

Horn Fly
- Description: The horn fly is very tiny, measuring around 3/16 of an inch in size. It is a type of blood feeding fly that preys on cattle and horses. The horn fly is often found on the shoulders, back, or stomach of its host. This particular type of fly consumes about 25 meals of blood a day, and only leaves the host to lay eggs in their feces. Studies show that these flies affect growing animals the most. With an average of almost 200 flies feeding on an individual foul/calf every day, there may be up to 15 pounds of growth deficit between an afflicted foul/calf and one that is protected from these nasty pests.

The house fly is dark blue or black with four black stripes running parallel to its body and dark red eyes. Its wings are transparent.

These flies acquire protein by feeding on the blood from open wounds and secretions along the face of its host.
