What causes Summer Eczema Horse Summer Itch?

The cause is a gnat called Culicoides with nicknames of “biting midge” and “no-see-ums”.  They cause a painful bite, and after they bite, suck blood from the area.  They are called “no-see-ums” because they are only the size of a period at the end of a sentence.  You feel a bite but you can’t tell what it is from.  Their saliva has foreign proteins containing antigens which set off a reaction in the horse’s skin in six- to twenty-four hours after a bite.  The reaction causes the redness and itchy condition.

Insect hypersensitivity reactions are documented as the most common allergic reaction of horses and Equine Summer Eczema/Horse Summer Itch (SE) falls into this category.  Horse Summer Itch is recognized as the #1 cause of mane and tail rubbing in research and is the #1 hypersensitivity reaction in the horse.

What are the symptoms of Equine Summer Eczema/Horse Summer Itch?

The allergic reaction causes hair loss, inflamed skin on the belly, mane, and tail.  The itchy condition will limit or eliminate riding.

Will my other horses get Equine Summer Eczema Horse Summer Itch?

Only a few horses in a herd are usually affected because it is an allergic condition, and the conditions are not contagious.  A horse with affected skin will not transmit it to another horse or person.  There is a genetic component to Horse Summer Itch – offspring of affected horses are more prone to have Horse Summer Itch.

Summer Eczema Horse Summer Itch: Management to AVOID AN OUTBREAK

2 things you need to order:

1. Horse Summer Itch/Summer Eczema Oral Supplement:  Only need to give 20cc once a day in feed.  In states with constant warm weather (California, Florida…) need to use year round.  In states with a cold winter, Start April 1st and go until mid-November.  (Medication dose is 20cc once a day and a bottle will last 48 days.)

2. RK Topical Horse Fly Spray: Apply twice a day.  Need 2 bottles a month per horse to apply 2 times a day for 30 days.


1. Fans: Blow Culicoides physically away from the horse.

 2. Daytime Turnout: Culicoides Gnats feed at night.  Be in a stall with a fan at night, or reapply RK Topical Spray at dusk if outside continuously. Use RK Topical Spray in the mornings to avoid greenheads, horse flies, barn flies that damage skin and then Culicoides attacks these areas at night.


3. Remove Standing water areas on farm.  They live/breed in stagnate water so if removed, will cut down on population.  They do not live in streams. Put blue stone around waterers to avoid lots of mud which can hold water in a horse shoe impression.


4. Omega Oils added to feed. A Canadian study shows it helps to decrease itchy skin.

Two great alternatives  in the feed once a day:
Flax Seed – Ground – #1 Source of Omega 3’s in plants.  Great 4:1 ratio of Omega 3 to Omega 6. Give Four (4) Tablespoons a day.

Whole Chia Seed – #2 Source of Omega 3’s in plants.  Great 3:1 ratio of Omega 3 to Omega 6. Give 2 Tablespoons a day.


5. Deworming for Skin Internal parasites rob your horse’s immune system.  We recommend giving one (1) tube of Equimax dewormer once a week for FOUR (4) WEEKS IN A ROW. This really can help your horse be at its best to protect the skin.  Also, in case they have Equine Summer Eczema/Horse Sweet Itch and Onchocerca together, this helps both.  Black flies can transmit an Onchocerca live larvae onto the skin and they borrow under the skin creating itching.

6. Give your horse a bath with your regular shampoo (even Dawn dish soap works) two to three times a week.  Any soap can help in prevention.  Why?  Horse urine attracts flies over thirty times greater than other large animals.  You can cut down on exposure by removing the attraction.  Also hose your horse off after rides.  Once dried off, apply RK Topical Horse Fly Spray™.
