Parasites & Skin Conditions

Guinea Pigs can contract a number of skin conditions and parasites. It is important to be familiar with the signs and symptoms, so you can treat any issues early.

If you think your piggy has contracted a skin condition, we don't recommend self diagnosing, or leaving it to go away on it's own. Most of these ailments will worsen over time, spread to other piggies and can become of severe risk to your piggy's health.

We highly recommend seeking the advice of an exotics vet if you have any doubt, as they will confirm your pets' diagnosis and get it treated correctly!

Mange Mites

These mites are very painful causing skin lesions, itching and hair loss. They are microscopic, meaning they cannot be seen with the naked eye. It is vital that treatment is offered as soon as possible, as these burrowing mites can cause severe illness and, in some cases, death. Skin can get thick and sometimes yellowish and crusty with accompanying hair loss in the affected areas.

Biting Lice

These parasites can be seen with the naked eye. Often residing near the guinea pigs ears, head, rear and neck. Skin can appear dry and scaly with the presence of scabs.

Static / Hay Lice

Another type of fur mite guinea pigs can contract is called Static Lice or Hay Lice

They are tiny mites called Chirodiscoides caviae, which are often found in hay and feed on skin debris, hence the name "hay mites" or "static lice".

Your guinea pigs may exhibit restlessness and discomfort due to the irritation caused by these mites.

Ringworm

Fungal infections in guinea pigs are usually caused by dermatophytes and are commonly known as ringworm. Despite the name, ringworm is not a worm—it's a fungus, and it can spread quickly if not treated.

Guinea pigs are more likely to get ringworm if they have a weakened immune system, are under stress, or are living in damp or dirty conditions.

⚠️ Important: Ringworm can spread to humans!
If you notice a small, itchy, flaky patch on your skin (especially on your hands, feet, or legs), head to a pharmacy. An over-the-counter antifungal cream usually clears it up within a few weeks.

How to Prevent It:
✅ Keep their cage clean and dry
✅ Use soft, absorbent bedding
✅ Avoid overcrowding
✅ Feed a balanced, healthy diet
✅ Reduce stress in their environment
✅ Wash your hands after handling them—especially if one is showing signs of infection

With good care and hygiene, fungal infections can be easily prevented and treated.
