Mango Worms in Dogs: Causes, Symptoms, and Treatment for Stomach and Upper Body Infestation

Mango worms — also known as Cordylobia anthropophaga or African tumbu fly larvae — are one of the most unpleasant parasites that can infect dogs. These worms burrow under the skin, especially on the stomach, chest, and upper body, causing painful swellings and severe discomfort. Although mango worm infections are most common in tropical regions, pet owners everywhere should understand how to recognize, treat, and prevent this problem.

This article explains everything you need to know about mango worms in dogs, including how they infect pets, symptoms to watch for, safe treatment methods, and preventive care tips.

What Are Mango Worms?

Mango worms are the larvae of a fly species found mainly in warm, humid regions of Africa and parts of Asia. The adult fly lays its eggs on soil, clothing, bedding, or animal fur that has been contaminated with urine or fece. When a dog lies on or near that area, the larvae penetrate the skin through hair follicles or small wounds.

Once inside, each larva creates a tiny pocket under the skin and feeds on the dog’s tissue fluids. Over time, a visible swelling forms, and the larva continues to grow until it is ready to emerge.

How Dogs Get Mango Worms

Dogs usually get mango worms by coming into contact with infested soil or contaminated materials. Common causes include:

Rolling in dirt or sand: Stray or outdoor dogs are more exposed since they often lie on the ground.
Unwashed bedding: Flies can lay eggs on fabric or blankets that have not been cleaned regularly.
Poor hygiene: Dogs that are not bathed or groomed frequently may attract flies that carry the eggs.
Open wounds: Cuts and scratches provide easy entry points for larvae.
Warm and humid environments: These climates are ideal for mango fly breeding.

Puppies and dogs with weaker immune systems are at higher risk of infection.

Symptoms of Mango Worms in Dogs’ Stomach and Upper Body

The first signs of a mango worm infestation can be subtle. However, as the larvae grow, symptoms become more visible and uncomfortable for the dog. Common signs include:

Small bumps or boils on the skin (especially on the stomach, chest, and shoulders)
Swelling and redness around the affected area
Intense itching or irritation causing the dog to scratch or bite the spot
Pus or fluid discharge from the swelling
Pain and sensitivity when touched
Tiny breathing hole at the center of the bump (this is where the larva breathes)
Fever and restlessness in severe cases

If you notice these symptoms, it’s important to act quickly to prevent further infection or spreading.

Why the Upper Body and Stomach Are Commonly Affected

The stomach, chest, and upper body of a dog often touch the ground when lying down, making them prime targets for fly eggs or larvae. These areas also have thinner skin, making it easier for larvae to penetrate. In addition, dogs tend to lick or scratch these regions, which can worsen the infection or introduce bacteria.

Safe and Painless Treatment Options

Treating mango worms in dogs requires care, cleanliness, and sometimes professional help. Avoid squeezing or popping the bumps yourself, as this can cause severe pain or infection. Here are safe treatment steps:

1. Veterinary Removal

The best and safest way to remove mango worms is to visit a veterinarian. The vet can:

Apply a topical anesthetic to numb the area
Gently extract each larva using sterile tools
Clean and disinfect the wound to prevent bacterial infection
Prescribe antibiotics and anti-inflammatory medications

2. Home Care (if professional help isn’t immediately available)

If you live in an area without easy veterinary access, you can follow these emergency steps:

Apply petroleum jelly or coconut oil to the swelling to block the larva’s air supply.
After 10–15 minutes, the larva may crawl out.
Use clean tweezers to remove it gently — never squeeze.
Wash the wound with antiseptic solution like diluted Betadine.
Apply an antibiotic cream and cover it with a clean bandage.

Even after removal, always visit a vet as soon as possible to ensure all larvae are gone.

3. Medications

Your vet may prescribe:

Antibiotics to prevent secondary infection
Anti-parasitic medicines like ivermectin (in appropriate dosage)
Pain relief or anti-inflammatory drugs for comfort

Aftercare and Healing

Once the worms are removed, proper wound care is essential for healing:

Clean the area daily with mild antiseptic.
Prevent your dog from licking or scratching the wounds by using an Elizabethan collar.
Feed a nutritious diet to strengthen immunity.
Watch for any signs of reinfection, such as new bumps or discharge.

Complete healing usually takes one to two weeks, depending on the severity of the infestation.

Preventing Mango Worm Infestation

Prevention is always better than cure. Here’s how to protect your dog:

Keep bedding clean: Wash your dog’s bedding, blankets, and towels regularly with hot water.
Maintain hygiene: Bathe your dog weekly using an antibacterial shampoo.
Use insect repellents: Apply dog-safe fly repellents, especially during humid months.
Avoid letting dogs lie on bare ground: Provide a clean mat or raised platform for rest.
Check your dog’s skin frequently: Regular grooming helps you spot early signs of infection.
Control flies around your home: Use screens, traps, or repellents to minimize exposure.

When to See a Vet

If your dog shows signs of pain, fever, or multiple large swellings, visit a vet immediately. Attempting to remove many larvae at home can be risky and painful. Professional treatment ensures complete and safe removal.

Final Thoughts

Mango worm infestations can be painful and distressing for both dogs and owners, especially when they affect sensitive areas like the stomach and upper body. However, with early detection, gentle care, and proper hygiene, you can protect your pet from this unpleasant parasite. Keep your dog’s environment clean, watch for any signs of skin irritation, and seek veterinary help at the first sign of trouble. A little prevention goes a long way in keeping your furry friend healthy, comfortable, and worm-free.
