Ear Mites in Rabbits (Psoroptes cuniculi): Symptoms & Treatment
- Ear mites in rabbits are usually caused by the parasite Psoroptes cuniculi, which irritates the ear lining and can create thick brown crusts often called ear canker.
- Common signs include head shaking, ear scratching, ear droop, pain when the ears are touched, and crumbly brown debris or crusting inside the ears.
- See your vet promptly if your rabbit has crusting, stops eating, seems painful, or develops head tilt, balance changes, or a bad odor from the ears.
- Treatment often uses prescription antiparasitic medication such as ivermectin or selamectin, and your vet may also address pain, inflammation, or secondary infection.
- Do not peel off ear crusts at home. In rabbits, that can be very painful and may damage delicate tissue.
What Is Ear Mites in Rabbits (Psoroptes cuniculi)?
Ear mites in rabbits are a contagious parasitic skin disease caused most often by Psoroptes cuniculi. These mites live on the surface of the ear lining and feed on skin debris and secretions. As they irritate the ear, the tissue leaks serum and forms thick, brown, crumbly crusts. Many pet parents hear this called ear canker.
Some rabbits show mild itching at first. Others become very uncomfortable, shake their head, scratch hard enough to injure the skin, or hold one ear down. In more advanced cases, inflammation can lead to secondary infection, weight loss, and deeper ear problems.
The good news is that ear mites are usually very treatable with veterinary care. Early treatment matters. Rabbits can hide pain well, and severe ear disease can become much harder to manage if it spreads deeper into the ear or affects balance.
Symptoms of Ear Mites in Rabbits (Psoroptes cuniculi)
- Head shaking or repeated ear scratching
- Brown, tan, or gray crumbly crusts inside the ear flap or canal
- Pain when the ears are touched or handled
- Ear droop or holding one ear lower than normal
- Hair loss or scabs around the ears from self-trauma
- Bad odor, moist discharge, or pus suggesting secondary infection
- Reduced appetite, weight loss, or lower activity from pain and stress
- Head tilt, loss of balance, or rolling
Mild cases may start with subtle itching and a little debris. As the infestation worsens, crusts can become thick and painful, and the rabbit may resist handling. See your vet immediately if your rabbit stops eating, seems weak, develops a head tilt, loses balance, or has heavy crusting, discharge, or a foul smell from the ears. Rabbits can decline quickly when pain interferes with normal eating.
What Causes Ear Mites in Rabbits (Psoroptes cuniculi)?
Ear mites are caused by direct infestation with Psoroptes cuniculi. The mites spread most easily through close contact with an affected rabbit. That means newly adopted rabbits, bonded companions, rabbits from shelters or breeders, and rabbits living in groups are at higher risk if one animal is carrying mites.
The parasite is contagious, and shared bedding, grooming tools, or close-contact housing may help spread it. Poor sanitation does not always cause the problem, but crowded or hard-to-clean environments can make transmission easier.
Some rabbits also develop more severe signs than others. Stress, underlying illness, and delayed treatment can allow crusting and inflammation to build up. Once the ear tissue is damaged, bacteria or yeast may take advantage of the inflamed environment and create a secondary ear infection.
How Is Ear Mites in Rabbits (Psoroptes cuniculi) Diagnosed?
Your vet will usually start with a history and careful ear exam. In many rabbits, the combination of itching, head shaking, and the classic thick brown crusts strongly suggests ear mites. Your vet may use an otoscope to look more closely at the ear canal and check how much inflammation is present.
To confirm the diagnosis, your vet may examine ear debris or crust material under a microscope. Mites, eggs, or other life stages can often be identified this way. This helps separate ear mites from other problems that can look similar, such as bacterial otitis, yeast overgrowth, trauma, or skin disease around the ears.
If the ears are very painful, swollen, or infected, your vet may recommend additional testing or a gentler staged approach. That can include cytology for infection, sedation for a more complete exam, or treatment planning that avoids traumatizing the ear tissue. In rabbits, thick crusts should not be forcibly removed while the rabbit is awake.

Questions to Ask Your Vet About Ear Mites in Rabbits (Psoroptes cuniculi)
Bring these questions to your vet appointment to get the most out of your visit.
- Can you confirm whether this is ear mites, a secondary ear infection, or both?
- Does my rabbit need microscopy, cytology, or any other testing today?
- Which antiparasitic medication are you recommending, and how many doses will my rabbit need?
- Does my rabbit need pain relief or treatment for inflammation?
- Should bonded or in-contact rabbits in my home be checked or treated too?
- Do you want me to leave the crusts alone, and is there any ear cleaning I should avoid at home?
- What signs would mean the infection may be spreading deeper into the ear?
- When should we schedule a recheck to make sure the mites are gone?
How to Prevent Ear Mites in Rabbits (Psoroptes cuniculi)
Prevention starts with limiting exposure. Quarantine new rabbits before introducing them to your current rabbit, and ask your vet to examine newcomers if there is any scratching, crusting, or dandruff-like debris. Because ear mites spread readily through direct contact, one untreated rabbit can expose companions quickly.
Keep housing clean and dry, and wash or replace bedding regularly during and after treatment. Shared grooming tools, carriers, and resting areas should be cleaned if a rabbit in the home has mites. If your rabbit has a bonded partner, ask your vet whether both rabbits should be treated or monitored.
Routine wellness visits help catch early ear disease before it becomes painful. At home, check your rabbit's ears during gentle handling. If you notice head shaking, scratching, crusts, odor, or sensitivity, schedule a visit with your vet rather than trying over-the-counter ear products. Some products made for dogs or cats are not appropriate for rabbits.
