Flystrike

What is it?

Flystrike (myiasis) occurs when flies lay eggs on damp, soiled fur or wounds and the hatched maggots eat into the skin. It can develop within hours and is extremely painful and often fatal. Rabbits that can't groom normally, because of obesity, arthritis, dental disease, or diarrhea, are at highest risk. Florida's warm climate means flies are active much of the year.

What signs should I watch for?

Signs to watch for include maggots or eggs around the tail or rear; wet, dirty, or smelly fur; restlessness, then sudden lethargy; not eating; and collapse or shock.

How is it diagnosed and treated?

Flystrike is an emergency. Treatment typically involves clipping and cleaning under sedation, removing maggots, pain relief, fluids, and wound care, plus treating the reason the rabbit was soiled.

Can it be prevented, and what's the outlook?

• Check your rabbit's rear end daily (twice daily in hot weather), keep housing clean and dry, and address any cause of a dirty bottom.
• Ask about fly prevention products.
