Homemade Fly Spray For Horses With Permethrin

It’s easy to pick up a bottle in any tack shop, but to avoid nasty chemicals or add your own ingredients, try a homemade fly spray for horses with permethrin. Making your own fly spray is also one way to save money. Let’s take a look at insect-busting permethrin and how you can make your own bug repellents.

Protect Your Horse From Biting Insects

As soon as the weather warms up after winter, the bugs come out to irritate people and horses alike. Flies and mosquitos can spread disease and make horses uncomfortable, even driving sensitive horses crazy.

What Is Permethrin

Permethrin is a type of pyrethroid insecticide. While it is not a natural insecticide, it is quite similar to pyrethrum. Pyrethrum is a natural bug killer derived from chrysanthemum plants.

Pyrethroids are more stable than pyrethrum. While pyrethrum breaks down with exposure to sunlight and only protects for a couple of hours, permethrin lasts much longer, even days. It is one of the most effective fly sprays for horses and the least toxic.

Protect Your Horse From Biting Insects

Permethrin is effective on several types of bugs including, flies, ticks, and mosquitoes. The doses used in insect control don’t negatively affect people, but it is not completely safe. To avoid any of the effects, which usually only occur with exposure to high doses, stay inside when spraying property with it.

Is Permethrin Safe For Horses

Permethrin is toxic to flies and other insects. When they come into contact with it, it affects their nerves, leading to paralysis and death. However, it is considered safe for horses.

Safe Use Of Fly Spray For Horses With Permethrin

While fly spray will not eliminate insects on your property, it will deter them from landing on your horse and biting them. Insects are attracted by your horse’s body heat, and unfortunately, there is nothing you can do to stop this. However, if you use fly spray, the insect will avoid contact when exposed.

Always read product labels thoroughly before using them. Permethrin is sold in varying strengths, and sometimes it is combined with other products. Make sure when using a homemade fly spray for horses with permethrin, you use the recommended dilution. 

 

Even though it is rare, some horses experience sensitivity to permethrin. The most commonly seen issue is a skin reaction. If this occurs, give the horse a bath with a gentle shampoo and rinse thoroughly. 

Another side effect of permethrin use on horses is coat loss. This is usually due to the use of a highly concentrated product, such as a spot on. Always take caution to avoid contact with your horse’s eyes and nose.
