What Are the Bugs on My Hamster?

Hamsters, like many other pets, are susceptible to several types of mites, which can irritate the skin and cause scratching. By determining what type of mite is living on your hamster, you can determine the best treatment plan.

  1. Ear Mites

    • Ear mites are small, white insects that live in your hamster's ear canal and can be seen crawling around the skin. These mites irritate your hamster's skin and may leave rusty lesions in the ears and on the face and feet. Hamsters generally contract ear mites through contact with other hamsters or animals. Though, the mites themselves are not a threat, your hamster's scratching can lead to infection. To treat ear mites, take your hamster to a veterinarian, who can inject them with medicine to clear up the issue.

    Cheyletiella Mites

    • Cheyletiella mites are small, white insects that can be seen moving around the surface of your hamster's skin. They have garnered the nickname "walking dandruff" because of their appearance, according to HammysWorld. A true diagnosis of Chetletiella mites can be difficult, so your veterinarian may have to conduct a skin-scraping to be sure. The website says that the mites are not considered a long-term threat and your veterinarian can provide treatment.

    Burrowing Mites

    • Burrowing mites -- which, as the name suggests -- burrow beneath your hamster's skin, can cause your pet's skin to become itchy and inflamed. With the persistent scratching that comes with these mites, your hamster may lose lots of fur. According to HammysWorld, these mites can pose a serious health risk for your hamster, and you should consult a veterinarian immediately. The treatment process may prove lengthy. These mites can also cause an itchy rash on humans.

    Harvest Mites

    • Harvest mites are nearly-microscopic red insects that move quickly across your hamster's skin; eating the blood and flesh of your hamster. Like ticks, harvest mites suck the blood of their host and can cause itchiness and discomfort. Your hamster can become infected if you accidentally put contaminated leaves and grass in its cage. HammysWorld suggests consulting a veterinarian if you suspect your hamster has harvest mites.
