Does Diatomaceous Earth Help Cure Sweet Itch in Horses?

Diatomaceous earth is a naturally occurring, soft sedimentary rock that is easily crumbled into a fine powder. Composed mainly of the fossilized remains of diatoms, a type of hard-shelled algae, it has been found to offer a variety of benefits, particularly in the field of animal care. In this blog, we will explore how diatomaceous earth can be beneficial for horses, specifically in the treatment and prevention of sweet itch and mites.

Natural Pest Control

One of the primary benefits of diatomaceous earth for horses is its role as a natural pest control agent. When applied to the horse’s coat, the fine powder can act as a deterrent to mites and other external parasites. The sharp edges of diatomaceous earth particles are microscopic and not harmful to larger animals, but they can pierce the exoskeletons of mites and other tiny pests, causing them to dehydrate and die.

Safe and Non-Toxic

Unlike many chemical treatments used to combat mites and sweet itch, diatomaceous earth is non-toxic and safe for use around horses. This makes it an excellent choice for horse owners looking for a more natural approach to pest control. It’s important, however, to ensure that you are using food-grade diatomaceous earth, as this type is safe for animals.

Sweet Itch Relief

Sweet itch, also known as summer seasonal recurrent dermatitis, is caused by an allergic reaction to the saliva of biting insects, primarily midges. This condition can cause severe discomfort for horses, leading to intense itching, skin damage, and even infection. Diatomaceous earth can help manage sweet itch in two ways. Firstly, by reducing the population of biting insects around the horse, and secondly, by being applied directly to the horse’s skin to soothe and protect affected areas.

Improved Coat Condition

Regular use of diatomaceous earth can also contribute to a healthier, shinier coat. The abrasive nature of the powder can help remove dead skin cells and promote blood circulation
