Last Updated on October 19, 2022 by Allison Price

There are different species of flies in the world. While some are known nuisances, they can be still upsetting. Also, many species send and cause diseases. As a horse owner, it is important to practice the fly control program. This is to protect your horse’s comfort and health.

Here are some of the common flies that pester horses:


These are common cosmopolitan pests. They usually lay their eggs in moist and decaying organic substrates.

Horse Flies and Deer Flies

These are large and heavy bodied species that live along edges of ponds, lakes or streams.

Biting Midges

They are also known as punkies. These flies feed upon a variety of warm blooded hosts including humans. Although they are small, these insects inflict a fierce bite. They often result in a lesion that is more painful than of a mosquito.

Stable Flies

They have a slender, rigid, piercing – sucking proboscis projecting forward. Females and males feed on blood and are only on the host when feeding. They often cluster around feet and legs of different livestock.

Face Flies

They are a little larger than houseflies. They feed on cattle and horse secretions. That includes tears, saliva, nasal discharge, blood (from wounds/insects or placenta), serum.

Horn Flies

These are half the size of a house fly. They resemble the stable flies but more slender along with other subtle differences.

Fly Control Methods

Here are the three fly control methods we can always practice in managing a horse pasture.


We should always practice prevention of pests inside the barns, stalls, and pasture. This is by using the right product for pest control. In this way, we can reduce the number of flies early in the season. Also, breeding can be then prevented by using products that interrupt fly life cycles. Do not forget to practice daily sanitation. Always take housekeeping measures to reduce fly population inside and around the barn.


You can reduce larval habitats that are attractive to flies with regular cleaning. Keep any horse feed inside closed storage bins. Remove standing water to keep your barn and pasture areas clean and dry. Always dispose all wet feed and hay and ensure that garbage is then disposed. Also, you can use repelling sprays around the barn. Also, set traps for common nuisance flies outside. This is to discourage them from reaching the perimeter of the barn.


Maintaining pastures clean and employing good manure management is a tedious task. But this has to be done to control pests in the area. Manure should be then cleaned daily to keep the pastures healthy. Also, to prevent the growth of adult flies in the manure, use a feed-thru fly control product.
