Mango Worm Infestation in Dogs

Mango Worm Infestation in Dogs’ Mouth: Causes, Symptoms, and Care

Mango worms, also known as Cordylobia anthropophaga larvae, are skin parasites found mainly in parts of Africa. They infest dogs by burrowing under the skin, where they grow until they emerge. While they most commonly affect the body, paws, and underbelly, in rare cases larvae can appear around the mouth or muzzle, causing significant discomfort.

How Dogs Get Mango Worms

• Female flies lay eggs on soil, bedding, or clothing contaminated with urine or feces.

• When a dog comes into contact with these areas, the eggs hatch and the larvae burrow into the skin.

• Around the mouth area, infestation can occur if dogs rest their head on contaminated soil, lick infested bedding, or dig with their face.

Symptoms of Mango Worms in the Mouth Area

1. Swelling and Lumps – Raised, painful nodules that may resemble pimples or boils.

2. Small Breathing Holes – Tiny holes at the center of the swelling, sometimes oozing.

3. Excessive Drooling or Pawing at the Mouth – Signs of irritation.

4. Pain While Eating or Drinking – Because of swelling around the lips or jaw.

5. Secondary Infection – Redness, pus, and foul odor if bacteria enter the wound.

Why This Is Serious

• Mango worms cause severe pain and infection.

• Abscesses may form if larvae die under the skin.

• In the mouth area, swelling may interfere with eating, drinking, or even breathing if left untreated.

Treatment: What to Do

⚠️ Important: Never try to squeeze or cut out mango worms yourself. Incorrect removal can leave parts of the larvae behind, leading to infection or sepsis.

• Veterinary Removal – A vet will extract the larvae carefully and disinfect the wound.

• Cleaning & Dressing – The affected area will be cleaned with antiseptic.

• Medication – Antibiotics and pain relievers may be prescribed. In some cases, antiparasitic treatment is also given.

• Follow-up Care – The dog should be monitored daily until the wound heals.

Home Care After Veterinary Treatment

Once the vet removes the mango worms, you can support healing at home by:

• Cleaning the wound daily with mild antiseptic (as advised by your vet).

• Preventing licking or scratching with an Elizabethan collar (cone).

• Keeping bedding clean — wash in hot water and dry in the sun.

• Monitoring for signs of infection — swelling, pus, or bad odor.

Prevention Tips

1. Hygiene: Wash your dog’s bedding often, especially if you live in an endemic area.

2. Avoid Soil Exposure: Don’t let dogs sleep directly on soil where flies may have laid eggs.

3. Use Preventive Sprays: Ask your vet about safe insect-repellent sprays or spot-on treatments.

4. Regular Checks: Examine your dog’s body and mouth area frequently for unusual lumps or sores.
