Have you noticed unusual changes in your furry friend’s coat or behavior? Your hamster might be dealing with a tiny but troublesome issue – mites. Let’s dive into the world of these microscopic arthropods and learn how to keep your hamster happy and healthy.

What Are Mites in Hamsters?

Mites are minuscule arthropods, distant relatives of spiders and lobsters, that make their home on or within an animal’s skin. Hamsters commonly face mite problems, with two prevalent types being Demodex criceti and Demodex aurati, causing demodicosis (mange). Additionally, hamsters may encounter ear and nose mites.

Spotting Mites: Signs and Symptoms

How can you tell if your hamster has mites? Look out for these telltale signs:

  1. Hair Loss: Whether accompanied by itching or not, mites often cause hair loss.
  2. Scaling/Dandruff: Mites can lead to scaly-looking skin or dandruff.
  3. Scabbing and Lesions: Check for scabs and lesions along your hamster’s back, hindlimbs, or belly.
  4. Ear Troubles: Hamsters with mites may scratch around their ears or shake their heads.

Causes of Mites in Hamsters

Demodex, a mite family naturally residing in hair follicles, usually helps maintain healthy hair. However, in older or stressed hamsters, these mites can overgrow, causing hair loss. Other mite types may come from contact with other rodents or contaminated bedding.

How Veterinarians Diagnose Mites in Hamsters

If you notice suspicious lesions, your veterinarian may perform a skin scrape test. This involves gently collecting skin cells and examining them under a microscope to confirm mite presence.

Treatment: Ivermectin to the Rescue

The primary treatment for mites in hamsters involves administering ivermectin orally for 1-2 weeks. For ear mites, topical administration may be necessary, and affected ears might need cleaning. Severe cases may require medicated baths.

Recovery and Management Tips

While treating your hamster, maintain a clean cage environment. Disinfect cage items and replace bedding regularly using diluted bleach or white vinegar. If your hamster has a cage mate, quarantine them until treatment completion. Follow the vet’s prescribed medication schedule and confirm treatment success before stopping.
