If your pets are indoors this is not a common problem, but is a huge risk to outdoor pets, particularly rabbits.
Myiasis is a condition in which fly larvae eat an animal alive, and can kill it. There are many flies that can cause this problem, the most common being the blowfly.
Myiasis is also called Fly Strike, or Blowfly Strike.
The problem often starts at an open wound, the flies lay their eggs on the flesh, and the larvae hatch out and start eating into the rotting flesh, sometimes feeding on live flesh. The maggots spread bacteria infection to the bloodstream of the animal and effectively kill it.
In many cases the problem happens around the animals anus (bottom), which when dirty attracts flies even when their is no wound. The flies lay their eggs on and around the anus of the animal. The maggots then hatch and start eating the animal while it is still alive. This is very common in pet rabbits who are kept in outdoor hutches, and in sheep, particularly those in Australia where blowflies are very active in the summer.
You can protect your pet from fly strike by keeping an eye on it, making sure that there are no open sores, and that its rump is always kept clean, and dry. Cage areas should also be kept clean to prevent flies from being attracted. People who own pets in areas where blowflies are common can help their pet by keeping it indoors, rabbits in hutches face huge risks.
