Equine Operations

For many horse owners, fly control is more about health and animal comfort than profits. Flies also affect horse owners and the surrounding environment in many negative ways.

Horses’ environments can vary greatly. Consequently, they are exposed to many different fly species. ClariFly® Larvicide, a feed-through insect growth regulator, is designed to control pests from a wide variety of species, including house flies, stable flies, face flies and horn flies. Unlike conventional fly control methods like spray-on insecticides, ClariFly® Larvicide does not provide a direct kill to adult flies, but rather controls the larvae before they can become adults. It is important to point out that ClariFly® Larvicide should be one part of an integrated pest management program that includes cultural, physical, biological and biorational controls.

Understanding the Problem

There’s no getting around it; where there’s warm weather and horses, there are flies. Specifically, there are house flies, stable flies, face flies and horn flies. House flies and face flies feed on the horse’s eyes, body orifices and manure. They can spread fecal bacteria, and are vectors for costly diseases that affect both humans and horses. Notably, they can spread diseases like E. Coli and Salmonella to humans who spend time around the animals. Stable flies and horn flies give horses painful bites that can turn into welts; infestations of these biting flies can upset even the calmest horses.

Research shows that only about 5% of house fly and stable fly populations will reside on the horses themselves. The rest will perch on nearby fencing, ledges and vegetation. To identify perching sites, horse owners should look for “fly specks” – that is, small brown spots of fly waste.

House Fly

  • Feeds freely on human food, fresh animal waste and rotting garbage
  • Prefers manure and warm decaying organic matter as breeding sources
  • Spread diseases like E. Coli and Salmonella to humans who spend time around the animals
Understand horn flies, their feeding habits and the reasons why horn fly control is so essential for on operations by clicking this horn fly icon.

Stable Fly

  • Feeds on blood, inflicting painful bites on a variety of animals, including humans
  • Breeds in rotting vegetation, urine-soaked bedding and manure/vegetation mixtures
  • Give horses painful bites that can turn into welts

Fly Management Through IPM

Horse owners should be encouraged to control fly infestations with a complete integrated pest management (IPM) program. In addition to a feed through, an IPM program incorporates several routine practices and control methods that help keep fly populations in check.

Building an IPM program can be broken down into three phases; planning, implementation and evaluation.

How Feed-Through Products Work

Conventional insecticides – often referred to as adulticides – kill flies by attacking their nervous systems. Feed-through products such as ClariFly® Larvicide work by interrupting the fly’s life cycle rather than through direct toxicity. The active ingredient in ClariFly® Larvicide specifically targets flies in the larval stages of pupation by disrupting the proper development of an exoskeleton. Without an exoskeleton, flies are unable to survive into adulthood.

When a feed through like ClariFly® Larvicide is mixed into feed or feed supplements, horses ingest it as part of their daily intake. It then passes through the animals’ digestive systems and ends up in their manure, where flies lay eggs. It is here that the fly life cycle is ended. Use of ClariFly® Larvicide can result in more than 96% reduction in fly emergence in treated manure*.

For best results, horse owners should add ClariFly® Larvicide to their feed supplements 30 days before fly emergence (typically when average daily temperatures reach 65 degrees) and continue to do so throughout the season until 30 days after the first frost.
