### What are Horseflies? Horseflies are large, sturdy flies belonging to the Tabanidae family. Female horseflies need blood to produce eggs, often targeting large, dark-colored animals like horses, but they can also bite humans. ### How to Identify Horseflies Horseflies are larger than common houseflies, measuring about 6 to 20 millimeters in length. They have large eyes, segmented antennae, and strong, blade-like mouthparts. ### Signs and Symptoms of a Horsefly Bite A horsefly bite is painful and can cause redness, swelling, and minor irritation. Symptoms usually subside within a few hours or days. ### How to Treat a Horsefly Bite 1. Clean the bite area with soap and water. 2. Apply an ice pack to reduce swelling. 3. Use over-the-counter pain relievers if needed. 4. Apply an anti-itch cream to alleviate itching. ### When to See a Doctor Seek medical attention if you experience severe symptoms like dizziness, difficulty breathing, or excessive swelling. ### How to Prevent Horsefly Bites 1. **Insect Repellents:** Use repellents, though they may not be as effective as they are for mosquitoes. 2. **White Clothing:** Wear white clothing to make yourself less attractive to horseflies. 3. **Body Paints:** Brightly colored body paints can deter horseflies. 4. **Traps:** Use traps like black, shiny, sticky balls or malaise traps. 5. **Environmental Manipulation:** Clear bushes and drain damp areas to reduce breeding grounds.
