During the warmer weather, when green and blue bottle
flies hatch rabbits are at risk. These flies will
seek out dirty places, notably the anal region where
the faeces or urine has collected. They lay eggs there
and in about 24 hours the maggots hatch and begin
to feed on the body of the rabbit. It is absolutely
horrific and the prognosis is not good unless discovered
and treated in the early stages. There are, however,
certain precautions, which can be taken to help prevent
Hygiene: This is of the utmost importance,
especially during the warmer weather. Hutches should
be cleaned out thoroughly at least once a week, with
the dirty corners being done twice weekly. A spray
such as "Dynamite" is quite effective as
it deters flies.
Overweight Rabbits: If rabbits are
too fat they cannot easily reach to clean round the
anal area. All rabbits should be examined twice a
week and the dirty areas cleaned with an antiseptic
solution, e.g. savlon.
Fly Killers: These could be employed.
If the rabbits are kept inside a shed it will be easier
to control flies than if they are situated in outside
hutches or runs. Insectocutors and flypapers may be
used. Sprays of fresh lavender are also useful since
flies hate the smell.
Lavender: Lavender talc may be sprinkled
on the rabbits around the anal area in the summer.
If you see a rabbit sitting unhappily at the back
of the hutch, look at the anal area. If this is dirty
it is best to assume the worst. Make up a solution
of Savlon in warm water in a bowl and sit the rabbit
in the bowl for a minute. If a longhaired variety,
cut the fur off close to the skin. If the maggots
are present you may see one or two wriggling out.
Using tweezers (with great care) to remove any visible
maggots and ensure that the whole of the maggot is
removed. If the skin is broken or badly damaged apply
some antiseptic cream or powder.
There is a preparation called Negasunt powder, which
you can obtain from your Vet. The maggots soon burrow
deep into the body of the rabbit and usually do so
much damage that the animal cannot be saved, so it
is far better to try and prevent the problem than
to try and treat it.
