What is Fly Strike? What is Myiasis?

Fly Strike is a deadly killer of pet rabbits, it also occurs in sheep, and other animals. What to do if you find maggots on your pet rabbit? What is myiasis? What is fly strike? There are maggots on my rabbits bottom what do I do? I found maggots on my bunny how to remove them? Risks for rabbits kept outside. How to prevent fly strike?

Many people, even those who own pet rabbits, have never heard of this problem. For some their knowledge comes too late, their pet is already dead. Although Fly Strike is most common in rabbits, and sheep, it can occur in any vertebrate animal – even humans.

What happens usually is that an animals rump becomes dirty with feces (poop). This attracts flies who lay their eggs on the animals rear. Other times the problem starts when a wound is left open and untreated. The flies, attracted by the smell of rotting flesh, lay their eggs on the wound. Either way in 8 to 24 hours the eggs hatch and maggots are born.

Maggots have proven helpful to humans, and are sometimes uses in the medical field, particularly in therapy to eat dead flesh, but in this case they may be feasting on live flesh, particularly when laid on the animals rump. The blowfly (also known as the green-bottle, or bluebottle, fly) is the animal chiefly responsible for this condition, intentionally looking for such situations in which to lay their eggs. When Fly Strike occurs because of blowflies it is specifically referred to as Myiasis. Other flies, such as the housefly, may also lay eggs on an animals dirty rump, being attracted to it by the waste, although they were not intentionally looking for an animal to lay their eggs upon.

Either way the fly maggots eat the live animal. They release toxins into the animal and within a day bacteria infections also take hold. If untreated fly strike leads to death. In rabbits the problem of fly strike is a fast, and almost certain killer. The owner must take their pet to a veterinarian immediately.

Treatment of Fly Strike

Removal of the maggots is important, and an owner can try to remove some themselves, but rabbit skin is thin and requires gentle handling.  A veterinarian is more skilled and will have trained assistants and even anesthesia if needed. Additionally the vet can shave the animals rear and prescribe any antibiotics that the animal should be in need of to treat the bacterial infection. Fly strike should be considered an emergency situation.  Do not wait until the following day.

How to Prevent of Fly Strike

Prevention of fly strike, or myiasis is difficult, but not impossible. Talk to a vet in your area to find out how common this problem is and what preventative measures they suggest. Keep your pets bottom dry and clean. Rabbits generally do not like bathing, but if you bath your rabbit be sure it is thoroughly dry before you put it back in its cage. Pet rabbits who are kept outdoors need to be checked twice daily for signs of maggots. Their hutch can be covered with netting to prevent flies from entering.

In sheep this is one of the reasons why lambs have their tails docked at an early age. It should be noted that hair sheep do not have this problem as often. Keeping animals in uncrowded conditions and keeping the barn clean will also help keep flies from gathering.

Chickens, ducks, and guinea fowl, are known to be fond of eating flies and will keep their population down in an area.

A caution against using insecticides. Many are not effective against blowflies and these chemicals are always a risk around pets and other animals.

Interesting article, new information for me.

Eww! :-< Knew about this and lambs having their tails cropped. Curious that only today I read this and the part about 'hair sheep.' I just got home from a Field Trip through my son's school to a farm to see baby animals and they had a 'hair sheep.' I have never heard of these. The fur is not at all like the lanolin-laden sheep wool.

Good information there! Myiasis is a big headache for pet owners. Most of the treatment may harm the pet as well. I have written a new article using natural ways to treat this condition. It can be read here - http://www.holisticlivingannex.com/2012/06/best-natural-remedy-for-maggot.html

All the best pet owners.
