Rabbit ear mites can be treated at home with the right antiparasitic medication, careful ear care, and thorough cleaning of your rabbit’s living space. The process takes about four to six weeks from first treatment to full resolution, since the mite’s life cycle completes in 21 days and you need to outlast it. Here’s how to identify the problem, treat it effectively, and avoid the mistakes that make things worse.
Recognizing Ear Mites
The mite responsible for nearly all rabbit ear infestations is Psoroptes cuniculi, a parasite that lives its entire life on the host. Every stage, from egg to larva to adult, takes place inside your rabbit’s ears. Early signs are subtle: your rabbit scratches at its ears more than usual and shakes its head. If you look inside the ear at this point, you may see redness and swelling in the canal.
Left untreated, the infestation progresses quickly. The inflammation causes fluid and immune cells to ooze onto the skin surface, where they mix with mites, mite waste, and dead skin cells. This dries into the signature thick, brown or gray crusts that coat the inside of the ear flap. Your rabbit will be visibly agitated, scratching constantly. In severe cases the ears may droop under the sheer weight of the built-up scabs.
Do Not Remove the Crusts
This is the most important thing to know before you start treatment. It’s tempting to peel or pick the crusty buildup out of your rabbit’s ears, but underneath those scabs the skin is moist, hairless, and raw. Pulling crusts off exposes open tissue, causes significant pain, and creates an entry point for bacterial infection. As treatment works and the mites die, the crusts will soften and fall off on their own over a couple of weeks. Let them.
Treatment With Antiparasitic Medication
The standard home treatment uses ivermectin or selamectin (the active ingredient in Revolution for cats). Both kill the mites effectively, and you can administer them at home, though getting the correct product and dose from a rabbit-savvy vet is the safest route.
Ivermectin
Ivermectin is given either by mouth or by injection under the skin at a dose of 0.2 to 0.4 mg/kg of body weight. You repeat this every two weeks for a total of two to three treatments. Many rabbit owners use injectable ivermectin given orally (mixed into a small amount of food or syringed into the mouth), but the dosing must be precise because the concentration in livestock formulations is very high relative to a rabbit’s small body weight. A kitchen scale and a 1 mL syringe are essential for accuracy.
Selamectin (Revolution)
Selamectin is applied topically to the skin on the back of the neck, the same way you’d apply flea treatment to a cat. You must use the cat formulation, which has a concentration of 60 mg/mL. The dog version is a different concentration and should not be used. Dosing is weight-based: a rabbit weighing 3 to 6 pounds needs roughly 0.68 mL, while a 6 to 9 pound rabbit needs about 1 mL. This is applied once and typically repeated in two to three weeks.
Both medications are technically off-label for rabbits, meaning they’re approved for other animals and used in rabbits based on decades of veterinary experience. If you can get a vet to prescribe the correct dose for your rabbit’s weight, that’s ideal. If you’re dosing at home using livestock-grade ivermectin, double-check the concentration on the bottle and use an online rabbit dosing calculator to avoid overdose.
Why You Need Multiple Treatments
The entire Psoroptes cuniculi life cycle takes 21 days. A single dose of ivermectin or selamectin kills the living mites and larvae but may not destroy every egg. By treating again at the two-week mark (and potentially a third time two weeks after that), you catch any newly hatched mites before they can lay eggs of their own. Skipping the follow-up dose is the most common reason ear mites come back.
Cleaning Your Rabbit’s Environment
Treating your rabbit without cleaning the cage is a recipe for reinfestation. Psoroptes cuniculi mites can survive off the host for 7 to 20 days in a wide range of temperatures (roughly 40°F to 86°F) and humidity levels. That means bedding, litter boxes, fabric hides, and toys can all harbor live mites waiting to climb back on.
On the same day you give the first treatment, do a full clean of the enclosure:
- Bedding and litter: Throw out all of it and replace with fresh material. Do this again at each retreatment.
- Hard surfaces: Wash the cage, litter boxes, food bowls, and water dishes with warm water and a pet-safe cleaner like Nature’s Miracle. Rinse thoroughly.
- Fabric and soft items: Wash anything machine-safe in hot water. Items that can’t be washed can be sealed in a bag and placed in a freezer overnight, which kills mites at all life stages.
- Wooden items: Wooden chew toys and hideouts are porous and hard to disinfect. Freezing overnight works here too, or you can replace them if they’re inexpensive.
If your rabbit has free-roam time in parts of your home, vacuum those areas thoroughly and wash any blankets or rugs they contact.
Caring for Your Rabbit During Recovery
Once treatment begins, you should see a noticeable drop in scratching and head-shaking within the first week. The crusts themselves take longer to resolve. As the mites die and the skin underneath begins to heal, the scabs will gradually loosen and flake away on their own. This process usually takes two to four weeks. You can gently soften crusts by dabbing a small amount of mineral oil or coconut oil onto them, which also helps smother any surface mites, but resist the urge to pull.
Keep your rabbit’s nails trimmed during treatment. The intense itching in the early days makes them scratch hard, and long nails can break the skin around the ears, opening the door to infection.
If you have multiple rabbits, treat all of them at the same time, even if only one shows symptoms. Ear mites spread through direct contact, and the others are likely carrying mites that haven’t yet caused visible signs.
Signs of a Secondary Infection
Most ear mite cases resolve cleanly with proper treatment, but infections can develop when the raw skin under the crusts is exposed to bacteria. Watch for these warning signs:
- Foul smell: A strong, unpleasant odor from the ear indicates a bacterial infection has set in.
- Head tilt: If your rabbit holds its head permanently tilted to one side, the infection may have spread to the middle or inner ear.
- Loss of balance: Stumbling, circling, or rolling suggests inner ear involvement, which can become a chronic condition without treatment.
Any of these signs mean the infestation has progressed beyond what antiparasitic medication alone can fix. A bacterial ear infection in a rabbit requires antibiotics, and the wrong antibiotic can be fatal to rabbits (their gut flora is extremely sensitive), so this is not something to treat with leftover medication from another pet. A vet visit becomes necessary at this stage.
What Not to Use
Some home remedies circulate online that can do more harm than good. Avoid putting hydrogen peroxide, rubbing alcohol, or undiluted essential oils into your rabbit’s ears. These irritate already-inflamed tissue and can cause chemical burns in the ear canal. Flea treatments designed for dogs are also dangerous for rabbits. Stick with ivermectin or selamectin at the correct rabbit-specific dose.
