Best Fly Spray for Horses

Best Fly Spray for Horses: Top 5 Picks

Flies and insects aren’t just a nuisance to horses—they can also be hazardous because they carry diseases. Unfortunately, you can’t get rid of flies completely, but you can reduce their numbers.

Setting up fly-management plans, like a barn spray system that periodically dispenses insecticides into the air, can be costly. The most effective solution that improves the horse’s environment involves treating the horse itself. A cost-effective and helpful way to manage this issue is the use of fly sprays. While there are several types of fly sprays available in the market, this article will help you choose the best one to meet your needs.
