From time to time people have made various inquiries as to how to get rid of
mites on mice. I have often suggested putting flea powder in the bottom of the
cages, as my local pet store does. Some have responded that they think this
will harm the mice.
I have spoken directly to the small animal keeper at my local petstore
regarding fleapowder in mouse cages. She says they sprinkle a small amount in
the bottom of the cages before they put the litter in, and that they've been
doing this for at least three years while never enountering any problem with
it. The mice in their cages are sleek, energetic, and bright-eyed.
I've tried this with my own mice. I put a small amount, perhaps half a
thimble-full, in the bottom of the cage, put in the litter, and stirred it
around a bit to make sure it got everywhere, before putting the mice back in.
It has been ten days now, and I observe no change in their behavior or health
(other than, I assume, they are now mite free).
I will continue to suggest using flea power to treat mites on mice.
