ear mites in rabbits, photo progression

updated 19 May 2026

singapore’s year-round heat and humidity create near-ideal conditions for ear mite infestations. at 28 to 32°C with 70 to 90% humidity, Psoroptes cuniculi, the rabbit ear mite, can establish and spread quickly between rabbits living in close quarters. if you keep more than one rabbit in an HDB flat, a single missed case can move through your entire group in a matter of weeks.

ear mites are also one of the most misdiagnosed conditions among Singapore rabbit owners. exotic vets who treat rabbits are far less common here than cat and dog clinics, and the information gap shows. some owners treat with the wrong product, or dismiss early signs as ordinary ear dirt, and end up at the vet months later with a rabbit in serious discomfort. knowing what each stage looks like will help you catch it early and act with confidence.

what are ear mites

ear mites are microscopic parasites that live inside the ear canal and on the inner surface of the ear flap. the species that affects rabbits is Psoroptes cuniculi. they feed on skin debris and secretions, and their presence triggers a strong inflammatory response in the rabbit’s ear tissue.

the mites themselves are too small to see with the naked eye. what you observe instead is the accumulating damage they leave behind: brown or tan crusty deposits, inflamed skin, and eventually thick, layered scabbing that can fill the ear canal. the rabbit’s scratching and head-shaking compounds the irritation and can break the skin, opening the door for secondary bacterial infection.

ear mites are contagious between rabbits. they do not infect humans, but they will spread to guinea pigs and other small animals sharing the same enclosure or handling equipment.

photo progression: what each stage looks like

recognising the stage of an infestation helps you judge how urgently you need to act. here is roughly what you will see as the condition develops.

stage 1: early signs (first one to two weeks)

the first sign is a small amount of brown or reddish-brown flakiness near the base of the ear canal. it looks similar to ordinary ear wax but has a drier, more powdery or granular texture. your rabbit may occasionally shake its head or hold one ear slightly lower than usual. scratching is mild and easy to miss at this point.

this is the easiest stage to treat. if you notice it now, do not wait to confirm. book a vet visit.

stage 2: building crust (weeks two to four)

the debris thickens and expands. you will see a brown to dark tan crust forming along the inner ear flap and canal entrance. the texture becomes layered or honeycomb-like in some cases. the affected area can look like dried mud packed into the ear.

scratching becomes more frequent and deliberate. the rabbit may paw at its ear repeatedly and rub the side of its head against its enclosure. you may notice patchy hair loss around the ear base from the constant friction.

stage 3: heavy infestation (month one and beyond)

in untreated cases the crust can fill a significant portion of the ear canal and spread across the inner flap. it becomes thick, dark brown to almost black, and may carry a faint foul odour as bacteria begin to take hold. the skin underneath is raw, weeping, and visibly inflamed.

many rabbits reach this stage before owners realise something is wrong. rabbits are prey animals and suppress outward signs of pain. the gradual progression means each day looks only slightly worse than the last.

important: do not attempt to remove the crust yourself by picking, scraping, or using cotton buds. the skin underneath is often broken and bleeding. forcible removal causes significant pain and introduces bacteria. your vet manages crust removal as part of formal treatment.

stage 4: complications

in severe or long-untreated cases, the damage extends beyond the ear canal. crust may spread to the skin around the ear base, the neck, or the face. secondary bacterial infections are common at this stage. in rare cases the middle ear becomes involved, causing a persistent head tilt that requires extended antibiotic treatment to resolve.

if you see a head tilt, loss of balance, or crust spreading to the face, contact a SG exotic vet the same day. do not wait for a regular appointment slot.

how rabbits get ear mites in Singapore

the most common route is direct contact with an infected rabbit. this happens at pet shops, adoption events, multi-rabbit grooming appointments, or when a new rabbit is introduced without a quarantine period.

in Singapore, many pet shop rabbits are kept in shared group enclosures. mite infestations can circulate through an entire batch before the shop detects it. if you recently bought or adopted a rabbit, monitor the ears carefully for at least 14 days before allowing contact with your existing rabbits.

the local climate is a compounding factor. even air-conditioned HDB flats cycle between cool and ambient humidity throughout the day as doors open and occupants move between rooms. mites survive well in these conditions. keeping enclosures clean and well-ventilated reduces the risk but cannot eliminate it entirely.

bedding and substrate are not a major transmission route for Psoroptes cuniculi. direct animal-to-animal contact is the primary risk.

diagnosing at home vs at the vet

you can do a basic home check by gently folding back the ear flap and examining the inner surface under bright light. healthy rabbit ears are pale pink, smooth, and have little to no debris inside. some light, pale wax is normal for some rabbits.

if you see brown crust, dark layered deposits, inflamed or reddened skin, or your rabbit scratches or shakes its head more than once or twice a day, that is a reason to see a vet. do not try to self-diagnose by comparing photos online and then treating at home.

a vet diagnosis typically involves an otoscope exam and sometimes a skin scrape viewed under a microscope to confirm Psoroptes cuniculi. the vet will also check for secondary bacterial infection, which requires its own treatment. as of 2026, a basic exotic vet consultation in Singapore typically costs SGD 50 to 90, depending on the clinic and what is included.

do not use over-the-counter ear mite products intended for cats or dogs. the drug concentrations and carrier ingredients differ significantly. some are toxic to rabbits even at low doses.

treatment: what to expect at an exotic vet

treatment for rabbit ear mites in Singapore typically involves an antiparasitic agent applied topically to the skin, most often selamectin or ivermectin, at a dose and formulation chosen for rabbits. your vet selects the appropriate product based on your rabbit’s weight and health status.

treatment requires at least two applications spaced roughly two to three weeks apart to break the full mite life cycle. a single dose kills active adults but may not eliminate all eggs and larvae. your vet may also clean the ears during the initial visit once the rabbit has some medication on board.

if you keep more than one rabbit, all of them need to be treated at the same time, even if only one shows visible symptoms. treating one rabbit while others remain infected guarantees reinfection after a few weeks.

as of 2026, total treatment costs in Singapore typically range from SGD 80 to 200 for a single rabbit, depending on whether ear cleaning is performed, whether secondary infection requires antibiotics, and how many follow-up visits are needed. multi-rabbit households will pay more. ask your vet for a written treatment plan before you start.

most rabbits show clear improvement within one to two weeks of the first treatment. continued scratching or worsening after treatment means the mite species or secondary infection needs reassessment.

what owners often get wrong

treating only the symptomatic rabbit. if you have two or more rabbits and only treat the one that is actively scratching, relapse within weeks is almost certain. all contact animals need treatment simultaneously, full stop.

confusing wax with mites. some rabbits naturally produce more ear wax than others, and a small pale-brown deposit is not automatically cause for alarm. the key signals are dark brown colour, layered or crusty texture, and any scratching or head-shaking behaviour that accompanies it. wax alone, without those signs, is usually normal.

removing crust at home. this is among the most damaging mistakes. the crust sits over already-broken, inflamed skin. picking at it causes bleeding, intense pain, and opens the tissue to infection. leave crust removal to the vet.

stopping treatment after one dose. the mite life cycle runs roughly 21 days. one treatment kills adults on contact but leaves eggs and recently-hatched larvae. skipping the second dose allows a new generation to establish before the medication fully clears. follow your vet’s full protocol, even once the ears look clean.
