Rabbit Flystrike: Symptoms, Emergency Care, and Prevention

If you keep rabbits, flystrike is the word that should make every spring and summer morning a careful check. Rabbit flystrike symptoms can go from "something looks a little off" to life-threatening within hours — sometimes less. This is one of the few rabbit emergencies where every minute matters.

Here's what flystrike actually is, the signs to watch for, and exactly what to do if you find them.

What Is Flystrike?

Flystrike (medical name: myiasis) happens when flies — usually blowflies, greenbottles, or bluebottles — lay eggs on a rabbit, typically around the bottom or any soiled or damp fur. Within hours, those eggs hatch into maggots. The maggots burrow into the skin and begin eating the tissue, releasing toxins as they go.

In warm weather, eggs can hatch within 8–24 hours. Once maggots are active on the skin, a rabbit can deteriorate within hours.

Rabbits Most at Risk

Flystrike can happen to any rabbit, but the risk is highest in:

• Overweight rabbits who can't groom their back end properly
• Rabbits with dental disease (drooling, sticky chin fur)
• Long-haired breeds (Angoras, Lionheads)
• Older or arthritic rabbits who can't reach all areas to groom
• Rabbits with diarrhea or soft stools
• Rabbits with urine scald (wet, irritated skin around the back end)
• Outdoor or hutch-housed rabbits during warm months
• Any rabbit with open wounds

Early Symptoms

The earliest signs are subtle. Catching them at this stage gives the best chance.

• Tiny pale yellow or white eggs stuck in the fur — often looking like grains of rice around the bottom, tail, or genitals
• Damp, soiled fur that wasn't there before
• A change in behavior — your normally curious rabbit hiding, sitting hunched, or seeming tired
• Loss of appetite, even refusing favorite treats
• A foul, unusual smell from the rear end
• Restlessness or twitching around the back end

When to Worry — Established Flystrike Is a True Emergency

Once maggots have hatched and are active:

• Visible maggots crawling in the fur or on/under the skin
• Open wounds, sores, or ulcerated patches
• Foul-smelling, weeping, or bleeding skin
• Severe lethargy or collapse
• Tooth grinding (a rabbit sign of significant pain)
• Shock: weakness, cold ears, fast breathing, refusal to move
• No droppings produced (GI shutdown)

If you see any of these, call an exotic vet immediately and head in.

What To Do Right Now

If you suspect flystrike — even just eggs:

1. Call your exotic vet immediately, day or night. Don't wait until morning.
2. Take your rabbit indoors and away from flies. Move them to a cool, fly-free room.
3. If you see maggots and your vet says you can, gently remove visible maggots with tweezers — but do NOT delay your trip for this. Pick off what you easily can.
4. Do NOT bathe the rabbit yourself, soak them in water, or apply human insecticides. Wet rabbits can go into shock quickly, and many household products are toxic.
5. Do NOT try to cut away matted, soiled fur — you can easily nick the skin, which on a flystrike rabbit is extremely fragile.
6. Keep your rabbit warm, calm, and supported on a towel during transport.

How a Vet Treats It

Treatment usually requires sedation or anesthesia so the vet can fully examine the rabbit, clip away soiled fur, remove every maggot, clean wounds, and start fluids, pain relief, antibiotics, and supportive care. Many rabbits also need a few days of hospitalization.

Prevention

Flystrike is largely preventable:

1. Check your rabbit twice daily — especially the back end — during warm months. Run your hands gently over the fur, looking and smelling.
2. Keep enclosures spotlessly clean, with daily soiled-bedding removal in summer.
3. Use fly screens on hutches and windows; remove uneaten fresh food promptly.
4. Treat any soft stool, urine staining, or diarrhea as urgent — it usually means a diet, dental, or GI issue.
5. Help overweight or arthritic rabbits stay clean with gentle grooming.
6. Address dental disease — overgrown teeth cause drooling, sticky chin, and reluctance to cecotroph.
7. Talk to your exotic vet about preventive products, such as Rearguard (cyromazine), which prevents maggot development for several weeks in regions where it's available.
