🚨 THIS IS A MEDICAL EMERGENCY
Seek immediate veterinary attention. Do not wait or attempt home treatment. Every minute counts.
Flystrike (Myiasis) in Rabbits
A devastating condition where flies lay eggs on a rabbit's skin, and the hatching maggots feed on the rabbit's flesh. Occurs rapidly in warm weather. A true emergency that can be fatal within 24-48 hours.

When to Act
🚨 Immediate Emergency Care
Symptoms & Signs
Maggots visible on the skin
Small white worms (maggots) crawling on the rabbit's skin, usually around the rear end, genitals, or any wound.
Foul odor
Distinctive, unpleasant rotting smell.
Lethargy and collapse
Rabbit is extremely weak, may be in shock.
Skin damage
Open wounds, red/inflamed skin, missing fur where maggots have been feeding.
Behavioral Changes to Watch For
Pets can't tell us what's wrong. These behavioral changes are often the first clues that something is wrong.
🐾 Depression and immobility
Rabbit is too sick to move — often found lying in one spot.
What You May Notice:
Your rabbit doesn't respond when you approach and seems to be in a collapsed state.
Causes & Risk Factors
Causes
- •Flies (especially blowflies/Lucilia sericata) attracted to soiled fur, feces, urine, or wounds
- •Eggs hatch into maggots within hours in warm weather
- •Maggots burrow into and feed on living tissue
- •Secondary bacterial infection and toxin release cause shock
Risk Factors
- ⚠Warm weather (spring/summer)
- ⚠Obese or arthritic rabbits that cannot clean themselves properly
- ⚠Rabbits with a dirty rear end from diarrhea, urine scald, or poor husbandry
- ⚠Open wounds or skin infections
- ⚠Rabbits kept outdoors without proper hygiene
How It's Diagnosed
- 1Visual identification — maggots visible in the fur and on the skin
- 2Assess the extent of tissue damage
- 3Evaluate for shock and secondary infection
Treatment Options
Emergency Maggot Removal and Wound Care
Immediate veterinary intervention is required.
Steps
- 1.Clip and clean all affected fur
- 2.Manual removal of all visible maggots — this is painstaking and must be thorough
- 3.Flush wounds with sterile saline or dilute antiseptic (chlorhexidine)
- 4.Systemic antibiotics to treat secondary bacterial infection
- 5.IV fluids for shock
- 6.Pain management (buprenorphine + meloxicam)
- 7.Wound management — may require daily cleaning and bandaging
Expected Outcome
Survival possible with aggressive treatment if caught before extensive tissue destruction and systemic toxicity.
Precautions
- !Even one missed maggot can continue to cause damage
- !Shock and secondary infection are the main causes of death
Common Medications Used
| Medication | Usage | Important Notes |
|---|---|---|
| Meloxicam (Metacam) | Pain and inflammation management | Given alongside opioid pain relief for severe cases. |
Prevention
- ✓Check your rabbit's rear end daily — twice daily in summer
- ✓Keep the enclosure scrupulously clean — remove soiled bedding daily
- ✓Ensure the rabbit can groom properly — treat obesity, arthritis, or dental disease
- ✓Fly screens on outdoor hutches
- ✓Rearguard or similar preventive products applied in fly season
- ✓Keep rabbits indoors during high-risk summer months
When to See a Veterinarian
- 🚨ANY maggots visible — EMERGENCY, GO NOW (even at 3 AM)
- 🚨Foul odor from the rabbit
- 🚨Sudden lethargy or collapse in warm weather
Frequently Asked Questions
How quickly can flystrike happen?
Prognosis
Guarded. Survival depends on how quickly treatment begins and the extent of tissue damage. Rabbits caught early (hours, not days) have a reasonable chance.

A neurological condition where the rabbit holds its head twisted to one side, often with loss of balance. Most commonly caused by E. cuniculi infection or inner ear infection. Treatable if caught early.
severeDental Malocclusion in Rabbits
Rabbits' teeth grow continuously throughout their lives. When teeth don't align properly (malocclusion), they overgrow, causing severe pain, inability to eat, and secondary infections.
