What are Horse fly Bites?


Horsefly bites occur when female horseflies feed on the blood of humans and other mammals. These flies have sharp mouthparts that allow them to pierce the skin and suck blood. The bites are typically painful due to the horsefly’s bite mechanism.

Horseflies are most active during late spring, during hot weather, or the warm summer months. When a horsefly bites, it leaves behind a small wound and releases saliva into the skin. This saliva contains anticoagulant compounds that prevent blood clotting, allowing the horsefly to feed more easily. The body’s immune system reacts to these foreign substances, triggering inflammation, itching, and sometimes an allergic reaction.

Female horse flies require a blood meal to lay their eggs, or feed on blood sucking pests. Horse flies also like to feed on horses or anything that has foul odor. They have blade like mouthparts which tears through a horses skin fairly easily and leave small hooks in the skin.

Horsefly bites can vary in severity depending on the individual’s reaction and victim’s flesh. Some people may experience mild symptoms, while others may have more pronounced reactions. It’s important to take appropriate measures to treat horsefly bites and alleviate any discomfort increasing pain they may cause.

Symptoms of Horse Fly Bites?


Horsefly bites can cause a range of symptoms, which can vary from person to person. Here are some common symptoms associated with horsefly bites:

Immediate Pain

When a horsefly bites, it can be quite painful due to its sharp mouthpart piercing the skin.

Redness and Swelling

After being bitten by a horsefly, the affected area may become red and swollen. This inflammation is a natural response of the body to the horsefly’s saliva and the body’s immune reaction.

Itching and Irritation

One of the most bothersome symptoms of horsefly bites is intense itching. The saliva injected by the horsefly can cause an allergic reaction in some individuals, leading to persistent itching and discomfort. Scratching the bite can further irritate the skin and potentially increase the risk of infection.

Raised Bumps or Welts

Horsefly bites often result in raised bumps or welts on the skin. These can vary in size and appearance, depending on the individual’s reaction.

Secondary Infections

Although rare, horsefly bites can sometimes lead to secondary infections if the skin is broken due to scratching. It’s essential to avoid scratching the bite site to minimize the risk of infection. Additionally, If the bite becomes increasingly painful, shows signs of pus, or exhibits spreading redness, it’s advisable to seek medical attention.

Horse Flies and Insect Bites: Why Do Horse Fly Bites Itch?


When a horsefly bites, it injects a substance into the skin that prevents blood clotting, allowing it to feed more easily. This substance, along with the horsefly’s saliva, can trigger an immune response in the body, leading to itching and inflammation. Scratching the bite can further irritate the skin and increase the itchiness.

Treating Horse Fly Bites

If you’ve been bitten by a horsefly, here are some steps you can take to treat the bite and reduce itching:

Clean the Affected Area

Start by gently washing the bite area with mild soap and water to remove any dirt or bacteria that may have been introduced by the horsefly. Pat the area dry with a clean towel.

Apply Cold Compress

To alleviate pain and reduce swelling, apply a cold compress or an ice pack wrapped in a cloth to the bite area. The cold temperature helps numb the area and constrict blood vessels, reducing inflammation.

Use Over-the-Counter Remedies

There are various over-the-counter remedies available that can provide relief from itching caused by horsefly bites. These include antihistamine creams or lotions, hydrocortisone creams, and calamine lotion. Follow the instructions on the product packaging for proper application.
