Neil has helped rabbit and guinea pig owners in Swindon for over 35 years. In warm weather, one of the most serious small-pet risks is also one of the easiest for busy owners to miss: flystrike.
Flystrike is one of those topics I would rather explain before an owner ever sees it.
It can affect rabbits and guinea pigs, particularly in warm weather when flies are active. It is painful, serious and can become an emergency quickly. The frustrating part is that many risk factors are ordinary: dirty bedding, a damp rear end, soft droppings, wounds, old age, poor mobility, dental trouble or simply a hutch that is not being checked often enough.
That is why the twice-daily check matters. It is not fussing. It is basic summer welfare.
What Flystrike Means
Flystrike happens when flies lay eggs on an animal, often around dirty, damp or wounded areas. The eggs can hatch into maggots, and the condition can become life-threatening.
The BVA warns that flystrike is a life-threatening risk for rabbits and guinea pigs in warmer months and advises owners to check their bottoms twice daily. The RSPCA also reminds owners to check small animals for flystrike during summer.
This is not a wait-and-see problem. If you find maggots, eggs, wounds, a dirty rear end with weakness, or a rabbit or guinea pig that seems unwell, contact a vet urgently.
Why July Is A High-Risk Month
Warm weather means more flies. Heat can also make hutches smell faster, bedding spoil quicker and water intake change. Rabbits and guinea pigs may sit in one place more if they are hot, elderly, overweight or uncomfortable.
If an animal has soft droppings, dental problems, arthritis, wounds or a dirty rear end, flies are more likely to be attracted.
Owners often think flystrike only happens in neglected hutches. That is not true. It can happen to loved animals too, especially if checks are missed.

The Twice-Daily Check
- Check the rear end morning and evening
Look for dampness, mess, eggs, maggots, redness, soreness or smell. - Check bedding and corners
Remove wet bedding quickly. Warm, dirty areas attract flies. - Check appetite and movement
A rabbit or guinea pig that is quiet, weak or not eating needs attention. - Check water and hay
Good hydration and a high-fibre diet help support normal digestion. - Check the setup for flies
Use hygiene, airflow and safe prevention advice from your vet where needed.
Common Mistakes Owners Make
- Only checking the face
The animal may look bright at the front while the rear end is dirty or sore. - Assuming long-haired pets are fine
Long coats can hide dampness and mess. - Leaving wet bedding until the weekend
In summer, hygiene needs to be more frequent. - Ignoring a sticky bottom
This can point to diet, dental or digestive issues and should be taken seriously. - Trying to treat an emergency at home
Suspected flystrike needs urgent veterinary help.
Rabbit Owners Need To Be Especially Careful
Rabbits can hide illness and discomfort. A rabbit that stops eating, sits hunched, becomes quiet or has a dirty bottom should not be ignored.
Dental problems can affect how rabbits eat and groom themselves. Pain or stiffness can make cleaning harder. Overweight rabbits may struggle to reach their rear end. All of these increase risk.
If your rabbit has repeated dirty-bottom problems, speak to a vet rather than just cleaning the fur again and again.

Guinea Pig Owners Should Check Too
Guinea pigs also need clean, dry housing and regular checks. Long-haired guinea pigs can hide mess in the coat. Older guinea pigs or those with mobility problems may need extra monitoring.
Because guinea pigs need constant hay and vitamin C, diet quality matters. Poor diet can affect droppings and general health. Do not make sudden diet changes without understanding what you are doing.

What To Do If You Suspect Flystrike
Call a qualified vet immediately. Keep the animal calm and safe. Do not delay because it is evening or because the pet seems a little brighter after being moved. Flystrike can progress quickly.
This is not a problem to manage with internet advice alone.
Neil’s Honest Advice
The twice-daily check takes less than a minute once you are used to it. That minute can make an enormous difference.
In July, rabbit and guinea pig care is not just feeding and topping up water. It is checking the animal properly, keeping the enclosure clean and acting quickly when something is wrong.
