Rabbit flystrike in summer: spotting the emergency and preventing it
Flystrike, or myiasis, is one of the most feared summer emergencies in rabbits. Blowflies (notably Lucilia sericata) lay their eggs on a soiled or damp area of the animal, most often the hindquarters; the maggots hatch within hours and eat living tissue. The condition is well documented in veterinary medicine (research on Google Scholar) and moves extremely fast: a rabbit that looks fine in the morning can be severely affected by evening. Our other care pointers are in the rabbit care and grooming section.
Why rabbits are especially at risk
Flies are drawn to moisture and odours: urine, soft stools stuck to the coat, a wound, or simply a dirty perineal area. Overweight, elderly or arthritic rabbits, and those with digestive trouble, can no longer groom properly and stack up the risk factors. A rabbit producing soft stools because of an unbalanced diet is an ideal target, which is why prevention starts with good digestive health, as we explain in our article on rabbit GI stasis.
The signs that demand an immediate visit
Inspect the hindquarters: tiny white eggs (like grains of rice), maggots, a damp foul-smelling patch, matted fur. The rabbit may be withdrawn, refuse to move, or become suddenly lethargic. Flystrike is an emergency: it cannot wait until tomorrow and cannot be handled alone by picking off the visible maggots, because many stay buried. Head to the vet without delay.
Prevention beats treatment
In summer, check your rabbit's rear at least once a day, and twice for an at-risk animal. Keep the habitat clean and dry, remove soiling daily, and protect any outdoor space with fly netting. A rabbit that is too hot moves less and gets dirtier, so cooling its environment is part of prevention. Finally, treat any diarrhoea or soiled area straight away rather than waiting. Our care section covers grooming and hygiene routines that keep the coat clean: see the rabbit hub for the full set of guides.
Frequently asked questions
Does flystrike only affect outdoor rabbits?
No. Indoor rabbits are less exposed but not safe: a single fly through a window is enough if the animal has a soiled area.
Can I remove the maggots myself?
No, it is not enough: many maggots stay hidden under the skin. Only a vet can clean the area, manage the pain and prevent infection.
Are there preventive products?
Some veterinary products reduce the risk during the at-risk season: ask your vet rather than using a parasite treatment not designed for rabbits.
