Rabbit Ear Mites (Psoroptes cuniculi): Crusty Ears, Head Shaking, and Scratching Signs

TL;DR: Thick, brown, crumbly crusts inside your rabbit's ears — with head shaking, ear scratching, or a drooping ear — are classic signs of ear mites (Psoroptes cuniculi), also called "ear canker." It's treatable, but don't pick off the crusts at home: they're painful and can bleed. See a rabbit-savvy vet for prescription mite treatment, and go urgently if your rabbit stops eating, tilts its head, or loses balance.

What Ear Mites Look Like in Rabbits

The rabbit ear mite, Psoroptes cuniculi, lives on the surface of the ear canal and inner ear flap (pinna), feeding on skin debris and irritating the lining. That irritation makes the ear leak serum, which dries into the disease's signature finding: thick, tan-to-brown, crumbly crusts stacked inside the ear — often called "ear canker."

Early on you may only notice your rabbit shaking its head or scratching at one ear more than usual. As crusts build, the ear can look flaky, scabby, and red at the edges, and your rabbit may hold one ear lower than the other. A review of rabbit mange lists the typical picture as crusts, scabs, sores, and ulceration on the inner side of the ear flaps, together with "restlessness, irritation, itching and scratching, head shaking, drooping of ears" Arafa et al., Vet Med Int, 2022.

Left untreated, mites can spread from the ears onto the face, neck, and body, and heavy infestations cause discomfort and weight loss.

Why It Happens (and Whether You Can Catch It)

Ear mites spread by direct contact with an infested rabbit, or indirectly through shared bedding, hutches, carriers, and grooming tools — the 2022 review notes the main routes are "direct contact between infested and healthy rabbits or indirect contact with contaminated fomites or environment" Arafa et al., Vet Med Int, 2022. That is why a new rabbit, a recent boarding stay, or a bonded partner with itchy ears all raise suspicion — and why every rabbit in the household usually needs treating, not just the one showing crusts.

A common worry is whether ear mites jump to people. Documented human cases from rabbit ear mites are not well established, so the practical risk to owners is low — other rabbits are the real concern.

Ear Mites vs. Other Itchy or Head-Tilting Problems

Not every itchy ear or tilted head is mites. A true, persistent head tilt (torticollis) with loss of balance more often points to a middle- or inner-ear problem — including the parasite E. cuniculi — though neglected ear-mite infestations can extend deeper and contribute to it too. Vets confirm ear canker with a skin scraping of the lesion edge under the microscope Arafa et al., Vet Med Int, 2022. If the main sign is a head tilt rather than crumbly ear crusts, read our guide on E. cuniculi and head tilt.

How Ear Mites Are Treated

Do not clean or peel out the crusts yourself. They sit on inflamed, raw tissue and are very painful to remove while the rabbit is awake — once the right medication kills the mites, they loosen and fall away on their own within a couple of weeks.

Treatment is a vet-prescribed antiparasitic from the avermectin family, and the evidence is strong. In a randomized controlled trial, topical selamectin at 6 or 18 mg/kg left every treated rabbit "free from P. cuniculi mites on days 7 through 56," with no adverse reactions McTier et al., JAVMA, 2003. Ivermectin works well too: a controlled trial found rabbits treated with ivermectin spot-on had "the number of mites reduced to zero" Elhawary et al., Pol J Vet Sci, 2017. Your vet may add pain relief, treat any secondary infection, and advise on repeat dosing plus environmental cleaning to stop reinfestation. Avoid over-the-counter "ear mite" drops sold for cats and dogs — dosing and safety differ in rabbits, and the wrong product can do harm.

When to See a Vet

Ear mites do not resolve on their own, so any crusting or persistent ear scratching warrants a visit — routine for mild cases, urgent for the red-flag signs below.

• Thick brown or tan crusts building up inside one or both ears
• Repeated head shaking, ear scratching, or a drooping ear
• Sores, bleeding, or a bad smell from the ear
• Spread of crusts or scabs onto the face, neck, or body
• Urgent: head tilt, loss of balance, circling, or flicking eye movements
• Urgent: your rabbit stops eating or passing droppings, or becomes quiet and hunched (a rabbit that isn't eating is an emergency)

Frequently Asked Questions

Can I just clean my rabbit's ears at home to get rid of the mites? No. The crusts are painful, sit on raw skin, and cleaning them out does not kill the mites. Removing crusts too early can cause bleeding and worsen inflammation. Let a vet prescribe an antiparasitic; the crusts loosen and fall off on their own once the mites are dead.

Are rabbit ear mites contagious to my other rabbits or to me? They spread easily between rabbits through direct contact and shared bedding or carriers, so all rabbits in the home usually need treatment. Transmission to humans is not well documented and the practical risk to owners is low.

How long does it take for ear mites to clear up? With the correct prescription treatment, mites are typically eliminated within one to two weeks, and crusts fall away over roughly two weeks. In one trial, treated rabbits were mite-free from day 7 onward. Follow your vet's full course to prevent reinfestation.

Will the crusts leave permanent damage? Most rabbits recover fully when treated early. Neglected infestations can lead to secondary infection reaching the deeper ear and, rarely, balance problems, so prompt treatment matters.
