Parasites in Hedgehogs

Parasites, particularly external mites, are a very common and significant health concern for African Pygmy Hedgehogs. Fungal infections like ringworm are also frequently seen. These conditions cause discomfort, pain, and can be indicators of other underlying health issues. Prompt diagnosis and treatment from a veterinarian are essential.

External Parasites

1. Mites (Caparinia tripilis):

   • Cause: Mite infestation is the most common skin problem in hedgehogs. These microscopic parasites burrow into the skin, causing irritation and quill loss. A small number of mites can be present without causing issues, but they can multiply and cause disease when the hedgehog is stressed or has a weakened immune system.
   • Signs: The most prominent sign is quill loss. You may find an unusual number of quills in the cage. The hedgehog will be very itchy, scratching frequently. You will also see dry, flaky skin, especially along the back and around the face. In severe cases, the crust can build up around the eyes and ears.
   • Action: This requires a veterinary visit. A vet will diagnose the mites by examining a skin scraping under a microscope. Treatment is very effective and usually involves a prescription anti-parasitic medication like ivermectin or selamectin. Never use over-the-counter mite treatments, as they can be ineffective and dangerous.

2. Fleas and Ticks:

   • Cause: These are less common in hedgehogs that are housed indoors. Ticks are more likely to be found on a hedgehog that has been allowed to roam outside. Fleas can be contracted from other household pets.
   • Action: If you find a flea or tick on your hedgehog, consult with your vet for a safe removal and treatment plan. Do not use products intended for cats or dogs without veterinary approval.

Fungal Infections

Ringworm:

This is not a worm but a contagious fungal infection of the skin and quills.

• Signs: The signs of ringworm can look very similar to mites. It causes patches of quill loss and flaky, crusty skin, often starting on the face and ears. The only way to differentiate it from mites is through a veterinary diagnosis.
• Action: Ringworm is contagious to other animals and to humans. A vet can diagnose it using a special lamp or by taking a culture of the skin and quills. Treatment involves oral or topical anti-fungal medications and can take several weeks to resolve. Thoroughly disinfecting the cage and all accessories is critical.

Internal Parasites

Internal parasites like worms are very uncommon in captive-bred hedgehogs and are not a routine concern for most owners. They are more likely to be found in wild hedgehogs.

Prevention

• Quarantine: This is the most critical step. New hedgehogs should be quarantined in a separate room for at least 30 days and checked by a vet before being introduced to the same environment as other pets.
• Good Husbandry: A clean, dry cage helps to prevent fungal growth. A proper diet and a low-stress environment support a strong immune system, which can keep mite populations in check.
• Reputable Breeder: Sourcing your hedgehog from a reputable breeder who practices good hygiene and parasite control can significantly reduce the risk of bringing home a sick animal.

Because the signs of mites and ringworm are so similar, and because mites can be very painful, any hedgehog with quill loss or flaky skin should be seen by a veterinarian for an accurate diagnosis and treatment.
