Biting Flies: Identification and Protection

Not all flies are harmless. Some bite, causing painful or itchy marks.

The short answer

Biting flies include horseflies, stable flies, black flies, sandflies and biting midges. They bite to feed on blood, often near water, animals and vegetation. Identify by size, shape and where bites occur, wear protective clothing, use repellents suitable for your age and health, use screens, and reduce breeding by managing waste and standing water. See a doctor for severe reactions.

Common types

• Horseflies: large and painful bites.
• Stable flies: look like houseflies but bite.
• Black flies and midges: tiny, clustered bites.
• Sandflies: very small, dusk biters.

Protection

1. Wear long, loose clothing.
2. Use repellents suitable for you.
3. Use screens and fans.
4. Manage waste, manure and standing water.

Bites

• Wash and avoid scratching.
• See a doctor for allergic reactions or infection.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
