Crusty ears, head shaking, and scratching often mean ear mites or an ear infection in rabbits. This article explains how to tell the difference from a healthy ear, why you must never pick off the crusts, and when your rabbit needs a vet for safe treatment.
Thick tan or beige crusts inside the ear, head shaking, ear scratching, and holding an ear at an odd angle usually point to ear mites (Psoroptes cuniculi) or an ear infection. Both need veterinary treatment, and mites are highly treatable. The most important rule is never to pull off the crusts yourself, because the skin beneath is raw and intensely painful.
Crusty ears, head shaking, and scratching often mean ear mites or an ear infection in rabbits.
A healthy rabbit ear is smooth and pink inside, clean, and odour-free. Your rabbit should not be scratching at it, shaking its head, or flinching when the ear is touched.
Ear mites produce a very distinctive picture: crumbly, tan or brownish crusts that build up inside the ear flap, often described as looking like cornflakes or wax. The ear becomes itchy and sore, so rabbits scratch, shake, and may develop scabs around the ear base. In lop-eared rabbits, whose ear canals are folded and warm, problems are easy to miss until they are advanced.
A healthy inner ear is smooth and pink, with no crusts, redness, or smell.
An ear infection may instead cause redness, discharge, a bad smell, head tilt, or loss of balance. A sudden head tilt is a red flag that needs same-day veterinary attention.
It is tempting to clean away the obvious crusts, but underneath them the skin is inflamed, broken, and extremely sore. Removing crusts at home causes pain and bleeding and can worsen the damage. Treatment works by killing the mites, after which the crusts loosen and fall away on their own. Let medication do the work.
Avoid pouring oils, home ear cleaners, or human ear drops into your rabbit's ear. These do not resolve mites reliably and can trap moisture or irritate already damaged skin.
A rabbit-savvy or exotics vet will examine the ear, often confirm mites by looking at a sample under the microscope, and prescribe an appropriate anti-parasitic treatment. Mite treatment is usually very effective, with rabbits becoming far more comfortable within days. Your vet may also give pain relief, since mite infestations are genuinely painful.
For an infection, the vet may examine deeper in the canal, sometimes under sedation, and prescribe medication based on the cause. Never use another animal's ear medication, as some ingredients are unsafe for rabbits.
Mites spread through direct contact and contaminated bedding, hay, and hutches, so treating the environment matters as much as treating the rabbit. During and after treatment, thoroughly clean and replace bedding, and treat any in-contact rabbits as your vet advises.
Clean, dry, well-ventilated housing reduces the risk of ear mites and infections.
In Hong Kong and Taiwan's warm, humid climate, damp bedding and poor airflow help parasites and infections thrive. Keep housing dry, clean, and well ventilated, and check both ears during weekly health checks, gently and without forcing folded lop ears open.
Can I treat rabbit ear mites with an over-the-counter product?
It is not recommended. Rabbits are sensitive to many parasite products, and dosing must be species-appropriate. A vet can confirm mites and prescribe a safe, effective treatment.
Are ear mites contagious to my other rabbits?
Yes. Mites spread easily between rabbits, so all in-contact rabbits usually need treatment and the environment must be cleaned.
Will the crusts come off on their own?
Yes. Once the mites are killed by treatment, the crusts loosen and shed naturally. Do not pick them off.
Why does my rabbit have a head tilt?
A head tilt can come from an inner-ear infection, among other causes, and is always a reason for urgent veterinary assessment rather than home treatment.
