Rabbit Flystrike: Emergency Signs, What To Do Right Now & Prevention
If you are reading about rabbit flystrike, a rabbit-experienced veterinarian is the best first step. This guide explains patterns owners commonly see. It does not diagnose or prescribe.
Flystrike (myiasis) happens when flies lay eggs on a rabbit, usually in soiled fur around the tail and rear. The eggs can hatch into maggots within hours, and the maggots eat into the skin.
Rabbit flystrike is a true emergency. It can become life-threatening within a day, so act immediately if you see maggots or a wet, smelly rear.
Important: If you see maggots, eggs, or a wet, smelly, matted rear, call a vet now, including an emergency clinic after hours. Do not wait until morning.
What Flystrike Is
Flies Attracted to Soiled Fur
Blowflies are drawn to urine, feces, and damp fur. They lay clusters of tiny cream-colored eggs, often under matted fur where owners cannot see them.
Maggots Within Hours
In warm weather eggs can hatch the same day. The maggots feed on skin and tissue and release toxins that can send a rabbit into shock.
Not Only Outdoor Rabbits
Indoor rabbits can get flystrike too, especially in warm months or if a fly gets into the house.
How Owners Spot Flystrike
Maggots or Eggs
Small white or cream eggs stuck to fur, or moving maggots around the tail, genitals, or any wound.
Wet, Smelly Rear
Damp, stained, or matted fur and a strong, rotten smell.
Sudden Behavior Change
Restlessness, digging at the rear, hiding, or sitting very still.
Collapse or Not Eating
Lethargy, not eating, weakness, or collapse can follow quickly as toxins build.
How Flystrike Starts
Flystrike almost always starts with a rear end that stays dirty or damp.
Sticky Droppings
Uneaten cecotropes or diarrhea stuck to the fur are the most common trigger. See rabbit diarrhea and cecotropes.
Urine Scald
Rabbits that dribble urine or sit in wet litter develop damp, sore skin. See bladder sludge.
Can’t Groom Properly
Overweight, arthritic, or elderly rabbits and those with dental problems struggle to clean their rear.
Warm Weather and Wounds
Risk rises sharply in summer. Wounds, bites, and dirty hutches also attract flies.
What To Do Right Now
Prevention every day
In warm months check your rabbit’s rear at least twice a day, keep litter clean and dry, use fly screens, and fix the cause of any sticky droppings or urine soiling.
Severe / urgent
Any maggots, eggs, or a wet, smelly rear: go to a vet now. Flystrike can become fatal within hours.
