Flea treatments for rabbits

There are a few safe and effective options for treating fleas in rabbits. Some of the most common flea treatments for rabbits include:

  • Topical flea prevention medication – There are a few topical flea medications that are formulated specifically for use in rabbits. These are applied to the back of the neck monthly. Some options include Revolution and Advantage II for rabbits. Always consult your vet before using any topical flea prevention.

  • Oral flea prevention medication – There is one oral flea prevention medication that is safe for rabbits over 12 weeks old – Comfortis. It comes in chewable tablets that are given once a month. Comfortis kills adult fleas and prevents future infestations.

  • Flea combs – Flea combs can be used daily to help remove live fleas and eggs. Make sure to get one specifically for rabbits, with fine teeth spaced close together. The fleas get caught in the teeth as you comb through the fur.

  • Vacuuming – Thoroughly vacuuming your rabbit's habitat once a week can help suck up flea eggs and larvae. Be sure to discard the vacuum bag afterwards.

  • Wash bedding – Frequently wash your rabbit's bedding in hot, soapy water to destroy any flea eggs or larvae that could be lurking.

When using any flea prevention on your rabbit, always read and follow label directions carefully. Some products formulated for cats and dogs can be toxic to rabbits. Stick to treatments that are made specifically for rabbits. And consult your vet if you have any concerns.

Safe medications for fleas in rabbits

There are only a few oral and topical flea medications that are safe to use on rabbits:


  • Comfortis – This chewable tablet kills fleas and prevents reinfestation for a month. It's safe for rabbits over 12 weeks old. The dosage is based on body weight.


  • Advantage II for Rabbits – Applied monthly, this medication contains imidacloprid to kill fleas. It's safe for rabbits over 10 weeks old.

  • Revolution for Rabbits – Applied monthly, Revolution contains selamectin to kill fleas, mites, and other parasites. It's safe for rabbits over 10 weeks old and 5 lbs.

Key things to note about flea medication for rabbits:

  • Only use products designed specifically for rabbits – never use dog/cat flea medication.

  • Read dosing directions carefully and follow them. Don't over-apply or double-dose.

  • Monitor your rabbit closely for any signs of reaction after applying. Discontinue use if any irritation occurs.

  • Consult your vet before starting any flea medication, especially if your rabbit has other health conditions.

Some flea products for dogs and cats can be very dangerous and even fatal to rabbits. So it's important to stick to rabbit-safe options. An oral medication like Comfortis or topical like Advantage II for Rabbits are your best bets for treating fleas safely in rabbits.

Flea combs

Flea combs are an effective and safe tool to help remove live fleas and eggs from your rabbit's coat.

What to look for in a flea comb for rabbits:

  • Fine teeth spaced close together – This allows the comb to catch even the tiniest fleas and eggs. Avoid combs with wide-set or blunt teeth.

  • Long teeth – Teeth should be long enough to penetrate down to the skin and catch fleas where they bite and lay eggs. Look for teeth around 0.6 inches long.

  • Single row of teeth – Double rows can be uncomfortable. Stick to a single row.

  • Metal comb – Metal teeth are more durable and less likely to break than plastic ones. Stainless steel combs last the longest.

To use a flea comb effectively:

  • Comb in sections – Lift a section of fur and place comb right against the skin, combing in the direction of hair growth. Move systematically across your rabbit's body.

  • Comb thoroughly – Go over each area multiple times to catch all fleas. Pay special attention to the neck, belly, tail, and hindquarters.

  • Rinse comb frequently – Rinse comb under warm water to remove fleas and eggs. You want to remove them from the fur, not just redistribute them.

  • Check for fleas – Examine comb after each stroke to see if you’re catching any live fleas.

  • Discard fleas – Drown fleas collected in the comb in hot soapy water.

  • Follow with brushing – Once combing is complete, brush your rabbit’s coat to remove any remaining flea dirt and dander.

Aim to comb your rabbit at least once daily when dealing with a flea infestation. You can decrease frequency once fleas are under control. Combine with other methods like vacuuming and flea medication for best results.

Cleaning your rabbit's enclosure and your home

To get rid of fleas in your rabbit's environment, a thorough cleaning is key. There are a few steps you should take:

Clean the rabbit enclosure:

  • Remove your rabbit – Place them in a closed room or carrier while you clean the cage/hutch.

  • Wash all bedding – Launder any blankets, towels, mats, or other bedding in hot, soapy water. Dry on high heat.

  • Dump litter – Discard all old litter, substrate, and droppings. Do not reuse.

  • Scrub surfaces – Use a gentle rabbit-safe cleaner/disinfectant to scrub down all hard surfaces in the enclosure to remove flea eggs and debris.

  • Rinse thoroughly – Double check for any soapy residue and rinse well. Rabbits can get sick if they ingest cleaning products.

  • Dry completely – Let the enclosure air dry fully before replacing bedding and returning your rabbit.

Vacuum your home:

  • Focus on carpets – Use the hose attachment and crevice tool to vacuum carpeted floors thoroughly near your rabbit's area. Vacuuming kills flea eggs and picks up some larvae.

  • Empty vacuum – Discard the vacuum bag or wash filter after use to prevent spreading fleas.

  • Use flea powder – You can sprinkle a light layer of flea powder formulated for home use over carpets and allow it to sit for 12-24 hours before vacuuming again.

Wash bedding:

  • Machine wash bedding – Any rabbit blankets, mats, or other textiles from around their space should be washed in hot, soapy water and dried on high heat.

  • Pillowcases/sheets – If your rabbit spends time on your bed, wash all bed linens.

Repeat cleaning weekly until fleas are gone. Thorough cleaning combined with flea treatment on your rabbit is key. Avoid using sprays, foggers, or chemicals that could be unsafe for rabbits.

Flea treatments that are NOT safe for rabbits

When it comes to flea prevention and treatment, there are quite a few products designed for cats and dogs that are NOT safe to use on rabbits. Here are some to avoid:

Flea powders

Flea powders are not recommended for use on rabbits. Powders contain insecticides that can be hazardous if inhaled or ingested by rabbits during grooming. Stick to other treatment methods.

A flea bath/flea shampoo

Flea shampoos and baths are also not safe. The insecticides used can be toxic to rabbits, especially if any gets in their eyes. Rabbits are also very susceptible to hypothermia from bathing. It's best to avoid flea shampoos or baths.

A flea collar

Flea collars contain concentrated pesticides on their surface which could cause poisoning if chewed or rubbed against by a rabbit. They are designed to work over months, which is far too long for a rabbit to wear a pesticide-treated collar.

Unsafe medications

Never use topical or oral flea control products made for dogs or cats. Common ingredient like permethrins, pyrethroids, and organophosphates can be very dangerous to rabbits. Only choose treatments labeled specifically for rabbit use.

Stick to gentle, natural methods like flea combs, vacuuming, and washing bedding as much as possible. For medications, only use products designed and labeled specifically for rabbits like Revolution or Comfortis. Avoid any flea treatments using powders, shampoos, collars, or chemicals made for other animals. Read labels carefully and consult your vet if ever unsure about choosing a flea treatment.

Are there any safe natural remedies for fleas?

There are a few natural options that can help deter fleas in a safer, more gentle way for rabbits:

  • Diatomaceous earth – The microscopic sharp edges of DE powder naturally kill fleas by damaging their waxy coating. Use food grade powder – not pool grade. Apply lightly around the rabbit's environment, not directly on them. Reapply after vacuuming.

  • Neem oil – Diluted neem oil sprayed onto bedding/housing can repel fleas and have insecticidal effects. Don't spray it directly onto the rabbit.

  • Herbal flea spray – A vet-approved flea spray using ingredients like peppermint, cedar, and rosemary oils can help deter fleas from bedding and housing when applied lightly. Avoid getting into eyes.

  • Vacuum & wash frequently – This helps remove flea eggs and larvae from the environment without chemicals.

  • Flea comb – A fine-toothed flea comb removes live fleas through gentle, manual removal.

  • Feed brewer’s yeast – Some claim this yeast supplement in rabbit food deters fleas, but there is limited evidence of efficacy. It won't treat an existing infestation.

While these natural options may help deter fleas, they likely won't fully eliminate an existing infestation. For severe flea problems, a prescription topical or oral flea medication from your vet will be most effective along with thorough cleaning. But the natural methods can be beneficial additions to your flea fighting toolkit. Always consult your vet before using any flea treatments, natural or medicated, on your rabbit.

How did your rabbit get fleas?

There are a few common ways rabbits can get infected with fleas:

  • Contact with wildlife – Rabbits living outdoors or with exposure to wild animals like raccoons, opossums or feral cats are at higher risk of fleas jumping onto them. Fleas can find easy host victims in your yard or outdoor housing.

  • New pet – Bringing a new rabbit into your home that already has fleas can introduce the infestation. Quarantine and treat any new rabbits before introducing them.

  • Hitchhikers – You or your pet could carry fleas inside on your clothing or fur after being outside. Larvae can latch onto pant legs or shoes.

  • Shared bedding – If rabbits share bedding or space with infested dogs/cats, they can pick up fleas from the contaminated environment.

  • Existing infestation – If you already have a flea problem in your home, your rabbit's environment has likely already been seeded with eggs and larvae. Vacuuming and washing all textiles is key.

  • Neighbors – Fleas from nearby homes can make their way to your yard and house, looking for a new host. Keep rabbits indoor or in protected hutches if flea problems are rampant nearby.

  • Seasonal – In warmer months, fleas thrive and reproduce more rapidly outdoors. Monitor carefully during summer/fall when fleas are most prevalent.

Fleas are very opportunistic parasites. Wherever there are potential mammal hosts, fleas will seek them out and infest. Stop fleas from spreading onto your rabbit by controlling them in your home, yard, other pets, and controlling wildlife access. Check for fleas any time new rabbits are introduced to your home or environment.

How to prevent fleas in rabbits

While not always possible to prevent fleas entirely, there are some steps you can take to reduce the likelihood and severity of infestations in rabbits:

  • Monthly topical prevention – Applying a rabbit-safe topical like Revolution or Advantage II prevents future flea infestations.

  • Keep indoors – Housing rabbits strictly indoors reduces exposure to wildlife, strays, and fleas in the environment.

  • Clean bedding weekly – Wash all blankets, mats, etc in hot soapy water to kill any eggs or larvae.

  • Vacuum regularly – Use hose attachment to thoroughly vacuum carpets, crevices, and floors around rabbit's space.

  • Quarantine newcomers – Isolate any new rabbits for at least 2 weeks and treat for fleas before introducing them.

  • Treat other pets – Treat all dogs and cats in the home with vet-approved flea prevention to stop the infestation cycle.

  • Diatomaceous earth – Apply food-grade DE powder lightly in rabbit housing and vacuum up after a few days. The sharp powder cuts fleas.

  • Inspect regularly – Groom and inspect your rabbit’s coat at least weekly looking for any signs of fleas. Catch infestations early.

  • Limit wildlife – Seal off any openings or cracks where wildlife could enter shed or housing with mesh or wood. Discourage wild visitors.

  • Trim vegetation – Keep grass, bushes, and plant growth around housing short to reduce shady moist habitat where fleas thrive outdoors.

  • Consider flea traps – Traps with light and vibration lure fleas in and trap them on sticky paper. Best used with other prevention methods.

Consistency is key with flea prevention. Maintaining clean housing, treating your rabbit monthly, and monitoring closely will go a long way in protecting them from infestations. Contact your vet at the first sign of fleas.

Signs of fleas in rabbits

Fleas can be tricky to spot on rabbits, so look for these signs:

  • Flea dirt – Black specks of dried blood flea feces. Part it in the fur to see if it leaves a red stain.

  • Itching/scratching – Rabbits may scratch, lick or bite themselves more trying to relieve itchiness from flea bites.

  • Skin irritation – Redness, scabs, hot spots or hair loss from intense flea infestation.

  • Anemia – In severe cases, heavy flea feeding can cause anemia from blood loss. Rabbits may seem weak or tired.

  • Tapeworms – Fleas can transmit tapeworm eggs. You may see tapeworm segments in the feces or around the anus.

  • Jumpy behavior – Some rabbits become more restless or jumpy when they have the sensation of fleas biting and moving in their coat.

  • Flea eggs – Tiny white eggs may be seen in the fur, typically around the hindquarters.

  • Adult fleas – Live adult fleas are more difficult to spot since they move quickly, but you may see them jumping on white fur. Use a flea comb to capture some.

Check your rabbit's coat thoroughly – especially down at skin level in the thicker fur. Seek veterinary care if you spot signs of anemia, skin infection or extensive irritation. Severe flea infestations require veterinary treatment. Catching issues early improves outcomes.

Can fleas cause any serious side effects in rabbits?

Yes, fleas can actually cause potentially serious medical issues in rabbits beyond just itching and discomfort:

  • Anemia – If flea infestation is severe, the cumulative blood loss can make a rabbit anemic.

  • Tapeworm infection – Fleas transmit tapeworm eggs between hosts. Tapeworms cause gastrointestinal issues.

  • Skin infection – Flea bites can lead to infected sores and abscesses called “hot spots” that require antibiotics.

  • Allergic reaction – Some rabbits may have an allergy and react severely to flea saliva. This causes intense itching, hair loss and scabbed skin.

  • Blood poisoning – Flea dirt can contaminate scratched skin lesions leading to bacterial infection in the blood (septicemia).

  • Dehydration – Severe itching and skin irritation may prevent a rabbit from drinking properly due to discomfort.

  • Toxin exposure – Oral flea prevention or unsafe treatments could cause poisoning if overapplied.

Signs of serious side effects include weakness, lethargy, reduced appetite, skin abscesses, and yellowish mucous membranes or skin from anemia/jaundice. Seek prompt veterinary treatment if your rabbit shows concerning symptoms. Untreated flea issues can become very dangerous.

Can a rabbit spread fleas to humans or other pets?

Yes, rabbits can introduce or exacerbate a home flea problem by spreading fleas to humans, dogs, cats and other pets. Here’s how:

  • Shared bedding – If rabbits have flea-infested bedding, those eggs and larvae can spread to other household pets that share or come in contact with the same textiles. Vacuum and wash thoroughly.

  • Common spaces – Fleas can jump off an infested rabbit and onto carpets, furniture, pet beds, or human clothing, then hitch rides to find other hosts. Restrict rabbit's access.

  • Pet interactions – Rabbits and cats or dogs that interact closely together while one has fleas allows the parasites to move between hosts. Treat all pets.

  • Human contact – Fleas may bite and feed on humans while hosted on rabbits, especially those handling/grooming an infested rabbit. Wear long sleeves when handling.

  • Life cycle – Once a rabbit introduces fleas, those parasites can lay thousands of eggs in the home that spread to create a full blown infestation over time as larvae mature.

Prevention is best. Treat fleas in rabbits promptly before they can spread.
