Myiasis Explained: Symptoms, Causes & Simple Treatment Tips

Ever heard of a condition where tiny fly larvae burrow into your skin or wounds? That’s called myiasis. It sounds scary, but most cases are treatable if you catch them early. This guide breaks down the basics, what to look for, and what you can do right now.

Causes and Types

Myiasis happens when certain flies lay eggs on a wound, sore, or even healthy skin. The eggs hatch into larvae that feed on tissue. There are a few common types:

• Cutaneous myiasis – larvae live under the skin, creating a boil‑like lump.
• Wound myiasis – larvae infest an open wound or ulcer.
• Nasopharyngeal myiasis – rarer, larvae enter the nose or throat.

Most cases involve flies that thrive in warm, humid climates, but travelers can pick them up anywhere if they’re not careful.

First Steps If You Suspect Myiasis

Notice a sore that looks like a small, moving bump or a tiny opening with white specks? That could be larvae. Here’s what to do:

1. Don’t panic. Stay calm and avoid squeezing the area.
2. Clean the spot gently with soap and water.
3. Cover it loosely with a sterile dressing to keep more flies out.
4. Seek medical help ASAP. Doctors can remove the larvae safely and prescribe antibiotics if needed.

Trying to pull the larvae out yourself can cause more damage, so professional removal is the safest route.

While you wait for a doctor, you can apply a warm compress. Heat forces the larvae to move toward the surface, making it easier for a clinician to extract them.

After removal, follow any wound‑care instructions you receive. Keep the area clean, change dressings regularly, and watch for signs of infection such as increasing redness, swelling, or fever.

Preventing myiasis is mostly about hygiene and protection. If you’re in an area where flies are common, wear closed shoes, use insect repellent, and keep any cuts covered. When traveling, avoid sitting directly on the ground and wash any clothing or gear that’s been exposed to dirt.

People with diabetes, poor circulation, or compromised immune systems are at higher risk because their wounds heal slower. Regularly check feet, legs, and any skin breaks if you fall into this category.

In summary, myiasis is a fly‑larvae infestation that can affect skin or wounds. Spotting the signs early, getting professional removal, and maintaining good wound hygiene can keep complications low. If you think you might have it, don’t wait—talk to a health professional right away.
