Flystrike in rabbits
PetPort EditorialLast reviewed
What is flystrike and how do I prevent it?
Flystrike is flies laying eggs on a rabbit's soiled or damp fur, usually around the rear, and the maggots that hatch within hours begin eating into living tissue. It kills quickly and is agonising. Any maggot found on a rabbit is a same-hour emergency, not something to clean off at home.
General guidance for pet parents, not a diagnosis. Every animal is different — confirm anything that concerns you with your veterinarian.
Quick reference
| Egg to maggot | Within hours in warm weather |
|---|---|
| Time to fatal | Often under 24 hours |
| Highest risk | Overweight, arthritic or dentally compromised rabbits with a soiled rear |
| Prevention | Twice-daily rear checks in warm months, plus a clean dry enclosure |
| Never | Bathe the rabbit or remove maggots yourself — shock and pain are severe |
| Root cause to fix | Whatever stops the rabbit keeping its rear clean |
What is happening
Flies are attracted to damp, soiled fur — most often on a rabbit that cannot clean itself properly because it is overweight, arthritic, has dental disease, or has soft droppings sticking to the rear. Eggs hatch within hours in warm weather, and the larvae burrow into skin.
Signs to watch for
- Maggots or small pale eggs, like grains of rice, in the fur around the rear or tail
- A sudden strong, unpleasant smell, and damp or matted fur
- Lethargy, unwillingness to move, or collapse — often out of proportion to what is visible
What you can do
- Check the rear and under the tail twice daily through warm and humid months
- Keep the hutch or enclosure scrupulously clean and dry
- Address the underlying reason for a dirty rear — usually diet, obesity or dental pain
See a vet if
Immediately, without any attempt to clean the rabbit first. Flystrike needs veterinary treatment for pain, shock and the maggots themselves. Do not bathe the rabbit or pick maggots off at home.
In India specifically
Warm, humid conditions across much of India mean fly pressure is near year-round rather than seasonal, so the twice-daily rear check that UK guidance frames as a summer routine should be a permanent one here. Outdoor hutches need fly screening, and any rabbit kept near a garden, kitchen waste or livestock is at markedly higher risk.
Common questions
My rabbit has a dirty bottom. Is that just hygiene?
It is a warning sign in its own right. A healthy rabbit keeps itself clean, so a persistently soiled rear means something is preventing it — obesity, arthritis, dental pain or soft caecotrophs from too many pellets. Fixing that cause is what actually prevents flystrike.
Can indoor rabbits get flystrike?
Yes. Flies get indoors easily, and an indoor rabbit with a soiled rear is still at risk. Indoor housing lowers the risk but does not remove it, so the twice-daily check applies to indoor rabbits too during warm months.
Should I remove the maggots before going to the vet?
No. Handling causes severe pain, maggots are usually far more numerous than the ones you can see, and rabbits in flystrike are often already in shock. Wrap the rabbit gently, keep it warm and quiet, and travel immediately.
What time of year is flystrike a risk in India?
Most of the year in most of India, and highest through the monsoon and the humid months either side. Unlike temperate countries where it is a short summer risk, Indian conditions support fly activity for far longer, so the checking routine should be continuous.
