How Do I Treat Guinea Pig Mites?

Alex Paul

Treatment for guinea pig mites is usually straightforward and effective. It is, however, essential to get an accurate diagnosis from a veterinarian, because there are other conditions with similar symptoms. Two injections of an anti-parasitic drug — often separated by one or two weeks — is usually enough to kill the parasite. Extra doses may be required in more difficult cases. It’s also important to thoroughly clean the guinea pig’s cage once it has been treated for mites to prevent re-infection.

Guinea pig mites are a common problem, especially because the parasites can sometimes enter the hutch on the animal's food or hay. There is a misconception that only guinea pigs kept outside can suffer from mites, but the condition also can affect house pets. Symptoms of guinea pig mites include constant itching and irritation. If the condition isn’t treated quickly, then the constant scratching may result in hair loss and scabbed skin. Guinea pigs suffering from mites are often sensitive to the touch and may be difficult to pick up.

The first step in treating mites is to obtain a professional diagnosis. In its early stages, mites can cause symptoms similar to other conditions, such as ringworm, which also can cause itching. A veterinarian should be able to distinguish between mites and other parasites using various tests. Lice also can be mistaken for mites, although lice may not cause the same degree of itching.

Most cases of guinea pig mites are relatively easy to treat. The animal is usually injected with an anti-parasitic drug — often a drug known as ivermectin — that kills the parasites. To be effective, the treatment usually needs to be given at least twice with a gap of two weeks between the injections. In severe cases, extra injections may be required. Alternate forms of anti-parasitic drugs don’t require injection and may be applied directly to the skin.

It’s also important to clean the cage once the guinea pig has received treatment for mites. This prevents re-infection through mites that may be hiding in the hay or bedding of the hutch. As a general rule, bedding in a guinea pig cage should be replaced at least twice a week, and the cage should be thoroughly cleaned once a week. It is almost impossible to prevent guinea pigs from getting mites, because they are difficult to spot and can easily enter the cage, but regular cleaning will considerably reduce the chances.

Frequently Asked Questions

What are the signs that my guinea pig has mites?

Signs of mite infestation in guinea pigs include excessive scratching, restlessness, patchy hair loss, dandruff, and in severe cases, seizures. You may also notice your guinea pig being more irritable due to the discomfort caused by the mites. It's essential to observe your pet closely for these symptoms and seek veterinary care promptly.

How are mites in guinea pigs diagnosed?

Veterinarians typically diagnose mites in guinea pigs through a physical examination and by taking skin scrapings to observe under a microscope. This allows them to identify the presence of mites or their eggs. In some cases, a vet might diagnose based on symptoms alone, especially if the infestation is severe and the signs are clear.

What treatments are available for guinea pig mites?

Treatment for guinea pig mites usually involves the use of ivermectin or selamectin, which are administered either topically, orally, or by injection. These medications are effective at killing the mites. Additionally, cleaning the guinea pig's environment thoroughly to prevent re-infestation is crucial. Always follow a veterinarian's guidance for treatment and dosage.

Can guinea pig mites be transmitted to humans or other pets?

Most mites specific to guinea pigs do not infest humans or other pets. However, some mite species can cause temporary irritation or redness on human skin. It's always a good practice to wash your hands after handling an infested pet and to treat all animals in contact with an infested guinea pig to prevent cross-infestation.

How can I prevent mite infestations in my guinea pig?

Preventing mite infestations in guinea pigs involves maintaining a clean living environment, regularly washing bedding, and avoiding contact with infested animals. Providing a balanced diet to keep your guinea pig's immune system strong is also important. Regular health check-ups with a vet can help catch and treat mites before they become a significant problem.

Is it safe to treat guinea pig mites at home?

While some over-the-counter treatments are available, it's best to consult with a veterinarian before attempting to treat guinea pig mites at home. Incorrect dosage or use of medication can harm your guinea pig. A vet can provide the correct diagnosis, treatment plan, and follow-up care to ensure the safety and health of your pet.

My vet had me give my guinea pig a bath when she had mites. I was given a special antimicrobial cleanser to add to the bath water. It worked fine, but required two more baths several days apart. I had to make sure she was totally dry afterward so that she didn't catch a cold.


@anamur-- Anti-parasitic medication works best for guinea pig mites. You don't have to go to the vet to get ivermectin. Vets usually give ivermectin shots which are expensive and also very painful for the animal.

You can get 1% topical ivermectin for small animals over the counter. To use it, you need to weigh your guinea pig and then use the dose chart to determine the dose. Measure the dose of ivermectin with a syringe and then apply that amount topically right behind the guinea pig's ears.

This is an easy and safe treatment for mites. I've used this method several times and it worked like a charm. At one point, I had eight guinea pigs and one of them gave all the rest mites. I couldn't afford to have them all treated by a vet, so I treated them myself with topical ivermectin. Just make sure to clean the cage and bedding frequently to prevent another infection after you do this.


My guinea pig has mites. I called the vet to ask about treatment and found out that the anti-parasitic drug is kind of expensive. I used to have hamsters before and I treated them at home for mites once. I used a simple remedy with water, witch hazel and antiseptic mouthwash.

Can I use the same remedy for my guinea pig? Are hamster mites and guinea pig mites treated the same way?

Is there another remedy I can use to treat my guinea pig's mites?
