Flystrike in Rabbits: Maggots, Skin Wounds, and Emergency Treatment
- See your vet immediately. Flystrike can damage tissue fast and may become life-threatening within 24 hours.
- Flystrike happens when flies lay eggs or larvae on soiled fur, moist skin, wounds, or around the rear end, and maggots begin feeding on tissue.
- Common signs include maggots, a foul smell, wet or matted fur, red or ulcerated skin, pain, hiding, weakness, and not eating.
- Treatment usually involves sedation, clipping and cleaning the area, removing all larvae, pain relief, fluids, wound care, and often antibiotics.
- Typical 2025-2026 US cost range is about $300-$800 for earlier, localized cases and $900-$2,500+ for hospitalized or severe cases.
What Is Flystrike in Rabbits?
Flystrike, also called cutaneous myiasis, is a medical emergency where fly eggs or larvae collect on a rabbit's skin or fur and hatch into maggots. These larvae are attracted to moisture, urine or fecal soiling, wounds, and inflamed skin. Once present, they can burrow into tissue and cause severe pain, infection, shock, and rapid decline.
In rabbits, flystrike often starts around the hind end, genitals, skin folds, or any open wound. Outdoor rabbits are at higher risk because of greater fly exposure, but indoor rabbits can get flystrike too if they have matted fur, diarrhea, urine scald, obesity, arthritis, dental disease, or another problem that makes grooming harder.
This is not a condition to monitor at home for a day or two. Rabbits can worsen very quickly, and some cases become fatal in less than a day. If you see maggots, smell a foul odor, or notice sudden weakness with dirty fur around the rear, your rabbit needs urgent veterinary care.
Symptoms of Flystrike in Rabbits
- Visible maggots or small white larvae in fur or a wound
- Foul odor from the rear end, skin fold, or wound
- Wet, matted, urine-soaked, or feces-stained fur
- Red, swollen, raw, or ulcerated skin
- Pain, flinching, tooth grinding, or resisting handling
- Lethargy, hiding, weakness, or collapse
- Reduced appetite or not eating
- Decreased grooming or trouble reaching the hind end
Any visible maggots, collapse, or refusal to eat is an emergency. Even before maggots are obvious, rabbits may show a bad smell, damp fur, skin irritation, or sudden quiet behavior. Because rabbits often hide illness, a rabbit that seems weak, painful, or unusually still should be seen promptly. If your rabbit has soiling around the rear end during warm weather, check the skin right away and call your vet the same day.
What Causes Flystrike in Rabbits?
Flystrike develops when flies are drawn to a rabbit's body and deposit eggs or larvae on fur or skin. The biggest triggers are moisture, odor, and damaged skin. Urine scald, diarrhea, fecal buildup, matted fur, and open wounds create the warm, damp conditions flies prefer.
Many rabbits that get flystrike have an underlying problem that makes normal grooming difficult. Common contributors include obesity, arthritis, spinal pain, dental disease, weakness, neurologic disease, and any illness that reduces movement or appetite. Large dewlaps and skin folds can also trap moisture and debris.
Housing and season matter too. Outdoor living, dirty bedding, poor ventilation, and warm weather all increase risk. Some myiasis-causing flies are more common in northern parts of the US and Canada, while blowflies and other species may target contaminated fur or wounds. In practical terms, any rabbit with a dirty rear end or skin wound can be at risk, whether they live indoors or outside.
How Is Flystrike in Rabbits Diagnosed?
Your vet usually diagnoses flystrike with a physical exam. In obvious cases, larvae are seen in the coat or wound. In earlier cases, the clues may be a foul smell, damp or stained fur, inflamed skin, pain, or tiny moving larvae hidden under matted hair. Because rabbits are prey animals and stress easily, your vet may recommend gentle sedation to fully examine the area and remove all debris safely.
Diagnosis is not only about finding maggots. Your vet also needs to assess how sick your rabbit is overall. That may include checking temperature, hydration, blood sugar, circulation, and pain level, plus bloodwork to look for dehydration, infection, or organ stress. If there is urine scald, diarrhea, obesity, dental disease, arthritis, or another mobility problem, your vet may suggest additional testing so the underlying cause can be addressed too.
In some cases, larvae may be submitted for identification, but treatment should not wait for that step. The priority is stabilizing the rabbit, removing all larvae, cleaning damaged tissue, and treating shock, pain, and secondary infection as needed.

Questions to Ask Your Vet About Flystrike in Rabbits
Bring these questions to your vet appointment to get the most out of your visit.
- You can ask your vet how extensive the tissue damage looks and whether the larvae appear limited to the skin or deeper tissues.
- You can ask your vet whether your rabbit needs sedation, anesthesia, or hospitalization today.
- You can ask your vet what pain-control plan is appropriate and how long discomfort is expected to last.
- You can ask your vet whether antibiotics are recommended in your rabbit's case and if a culture is needed.
- You can ask your vet what underlying problem may have led to the flystrike, such as urine scald, diarrhea, obesity, dental disease, or arthritis.
- You can ask your vet how to clean and monitor the area at home and what changes would mean an immediate recheck.
- You can ask your vet what the expected cost range is for today's care, rechecks, and possible escalation if your rabbit stops eating.
- You can ask your vet what prevention steps are most important for your rabbit's housing, grooming, litter setup, and daily rear-end checks.
How to Prevent Flystrike in Rabbits
Prevention starts with keeping your rabbit clean, dry, and easy to inspect every day. Check the rear end, tail area, skin folds, and any wounds at least once daily, and more often during warm weather or if your rabbit has mobility or grooming problems. Bedding should stay dry and be changed often. Litter boxes, food bowls, and water containers should be cleaned regularly so odor and moisture do not build up.
Work with your vet on any condition that makes self-grooming harder. Rabbits with obesity, arthritis, dental disease, diarrhea, urinary dribbling, or neurologic issues are at much higher risk. Trimming soiled fur around the hind end, managing urine scald promptly, and treating wounds early can make a major difference. Indoor housing can reduce exposure, but it does not remove risk if the rabbit's coat stays damp or dirty.
Good fly control around the environment also matters. Use screens where possible, keep housing well ventilated, remove waste promptly, and avoid letting damp bedding sit. If your rabbit is older, overweight, or has a history of a dirty rear end, daily hands-on checks are one of the most effective prevention steps. Catching moisture or skin irritation early is far easier than treating full flystrike.
