How Do Guinea Pigs Get Mites?

An infested guinea pig with mites will exhibit symptoms similar to dandruff. This condition can result in severe itching and flaking that leads to hair loss and weight loss; spread either directly from another infested animal, or indirectly by sharing bedding, food or accessories among them.

The Environment

Normal conditions will see small numbers of fur mites living symbiotically on a guinea pig’s skin. When their environment becomes unclean or stressed out, their immune systems may become compromised, making it more difficult to keep mites under control and leading to excessive itching or skin problems. Luckily, fur mites can usually be controlled through keeping living quarters clean, decreasing stress levels, and providing nutritionally balanced diets for their guinea pig.

Sarcoptic mites, small creatures that burrow beneath your pet’s skin, can cause serious itching, leading them to scratch excessively and develop secondary bacterial and fungal infections that eventually become life-threatening if left untreated. If you suspect that your guinea pig has mange please make an appointment with a veterinarian immediately – severe itching can even be life threatening!

Lice are similar to mites but differ by being insects that feed off of blood. Left untreated, lice can make guinea pigs extremely uncomfortable, leading them to scratch themselves into open sores which cause much distress for them and scratch themselves into open sores which become very infected over time resulting in weight loss, seizures or even death in extreme cases.

As lice and mites can be treated effectively with medications like Ivermectin or Selamectin from your vet, these treatments should be applied topically – however it must be noted that they cannot be purchased over-the-counter as they can be harmful to guinea pigs.

Noteworthy is also that some guinea pigs may harbor mites or lice without showing symptoms; this could be caused by stress, changes to their environment or pregnancy. As a result, it is essential that new guinea pigs brought into your home are quarantined, as any newcomers could potentially carry diseases which are transmissible among their herd.


Mites are commonly found on guinea pig skin and often don’t cause any noticeable issues, according to Southeast Denver veterinarians. But under certain conditions they can increase dramatically leading to extreme itching and dandruff. A Southeast Denver vet explains this could be caused by direct contact with another infected guinea pig or due to unhealthy living conditions, poor diet or stress as the culprit for such sudden increase in mite numbers.

Guinea pigs infected with mites can become very itchy, leading to constant scratching that leads to hair loss and bald patches on their skin. Because itching may be a telltale sign of disease or infection, any guinea pig experiencing persistent itching should be seen by a vet immediately; otherwise they could develop sores which bleed easily before crusting over or loss of weight may ensue.

Guinea Pig mites may live on the surface of their skin or burrow into it to cause itching, hair loss and red or scabbed areas on their body. Burrowing mites are more prevalent and may lead to itchy areas with reddened or scabbed areas on them that become itchy when scratched – this type of infestation could potentially become life threatening; they could cause weight loss as well as seizures if left untreated.

An adult guinea pig suffering from severe skin issues can be treated with Ivermectin, usually given orally but sometimes applied directly to its skin if tolerated by your vet. He or she will evaluate both fur condition and texture along with running tests. Ivermectin treatment typically lasts from several days up until all mites have been cleared away completely; you’ll need to keep checking them with your veterinarian throughout treatment and possibly afterwards to make sure infestation isn’t recurring.

Pregnant Guinea Pigs

Most guinea pigs carry mites that cause scabs, itching, dandruff, redness and hair loss in humans and other pets. These parasites can be spread directly by scraping skin for mites or lice or indirectly via bedding, food and accessories of an infested pet spreading it further to uninfected guinea pigs; pregnant guinea pigs are especially prone to these pests due to hormones produced to support development of an unborn foetus weakening immunity reducing immune systems against infestation by further weakening immune systems weakening their immune systems further weakening them further from any direct contact.

Chirodiscoides caviae mites, which specialize in infesting guinea pigs’ fur, can cause intense and potentially life-threatening itching in these pets. Scurried scratchers may damage their own skin leading to infections or hair loss. At its worst, this infection could become debilitating leading to weight loss, dehydration or even death of their host guinea pig.

Coccidia, a single-celled protozoan parasite that attacks intestinal parasites in humans and can infest guinea pigs alike, causes diarrhea and weakness that is treatable with oral medication. Another intestinal parasite known as pinworms also poses a threat and should also be given oral treatment to combat them.

Tumors can be an enormously painful problem in all age ranges of guinea pigs. Common locations where tumors may form include the skin, reproductive tract, blood vessels and mammary glands – difficult to treat without surgery or antibiotics. Additional illnesses including pneumonia, ringworm and scabies may require antibiotic therapy as well.

Lice and scabs (commonly referred to as ‘mange’) are extremely prevalent among guinea pigs. Although these parasites can spread directly between individuals through direct contact or sharing a cage with infested ones, most cases develop as the result of stress, illness or pregnancy which has caused weakening in immune systems.

Your veterinarian will examine your guinea pig for any signs of itching, scratching and other skin disorders. They may send a sample of its skin off for bacteria and fungus testing at a laboratory. Ivermectin, an approved product suitable for use on guinea pigs, can effectively eliminate both mites and lice; any other forms of insecticide (powders, sprays, shampoos or gels) could prove fatal for your pet’s wellbeing.


Guinea pigs may acquire mites for many different reasons, including infection and stress. When their immune systems become compromised due to illness or overexposure to chemicals in their environment, infections often follow, resulting in symptoms such as thrush or even more serious conditions like dermatitis – where an affected area becomes itchy, flaky and open sores appear on its skin surface.

Guinea Pigs that suffer from mange are especially prone to the mites found on them, which are highly contagious. You must ensure your pet receives proper medical treatment should any be found.

Mange is an often fatal disease that results in open sores that can spread quickly throughout an animal’s body, often manifesting itself through extreme stress or illness, but can even infiltrate other cages of pets in close proximity. Guinea pigs suffering from mange often become very itchy, scratching themselves until further skin injuries result – potentially even death can occur as a result.

Guinea Pigs infected by mites may develop both fungal and bacterial infections. Fungal infections typically appear as flaky white spots that your guinea pig is unable to brush away; they often occur around the back and rump areas and eventually thin out or fall out completely. Meanwhile, bacterial infections are less frequently diagnosed and treat; moreover, any wounds caused by such infection could cause extreme discomfort for both sides.

While guinea pigs may occasionally develop mites, there are steps you can take to help prevent their proliferation into an issue. Keep the cage clean, provide him with plenty of hay and bedding free from contaminants, limit exposure to other animals as much as possible and ensure plenty of fresh water at all times – any Southeast Denver veterinarian will be able to advise further regarding how best to keep him or her healthy while preventing parasite development.
