How to Protect Your Horse from Insects

Have you ever watched your horse twitch, stomp, or swish their tail from frustration? They are likely being bothered by flies or other flying insects.  We all know insects can be a nuisance, but did you know they can also cause a serious health problem, especially for horses? Understanding the impact that insects and other bugs can have on horses can help owners keep them safe from disease and irritation.

How Can Insects Hurt Horses

Biting insects cause more than just irritation in horses, insects can carry diseases, potentially causing an allergic reaction, skin infections, or serious disease. For example, mosquitoes can carry Equine Infectious Anemia or West Nile Virus. Flies can spread bacteria, causing eye infections, and ticks are known for transmitting Lyme disease. Consistent irritation can lead to weight loss, stress, and even behavioral issues.

Some insects target specific areas of your horse. Mosquitos prefer thin-skinned places, such as inside the ears and belly, while flies cluster near the muzzle, eyes, and ears. Ticks will nestle into your horse’s tail, between the legs, or mane. 

What is the Worst Season for Insects Biting Horses?

Spring and summer unleash a flood of insect activity. The increased humidity and warmer temperatures initiate optimal breeding conditions for insects. However, in regions like the MidSouth, where we still see warm days in the fall, activity may last through October or even November.

Ways to Keep Insects Off Your Horses

Physical Deterrents

Physical obstacles are one of the best defenses against biting insects. Try using a few of the following to protect your horse from insect bites:

• Fans in your horse’s stall to hinder flying insects
• Leg wraps to prevent flies from landing on your horse’s legs
• Masks and fly sheets to cover larger areas

Chemical Options

For quick relief, insecticides and chemical repellents may help control insect populations. Always make sure you choose products that are equine-safe and follow label instructions closely. Some of the best options include:

• Bait stations and fly traps to decrease the number of flies in the stable
• Topical sprays that are safe to apply on horses
• Feed-through insect growth regulators (IGRs) to deter future larvae from maturing

Environmental Changes

For long-term management, change your horse’s surroundings to make it less attractive to pests. Here’s a few strategies to try:

• Rotate pastures to decrease long-term insect contact
• Plant insect-repelling herbs like citronella and lavender around and near the stable
• Eliminate standing water to decrease mosquito breeding areas
• Ensure your horse has consistent access to fans, shade, and shelter
• Remove manure quickly to prevent attracting flies and other pests
