If it isn't one thing, it is another... first I had sneezy mice, then I had mice with prolapsed rectums... now I think my mice may have mites or lice. The good news, I guess, is that I do seem to be eliminating the problems and moving on to new ones instead of having a recurring problem that I can't get rid of.

On a few mice, I have seen spots on their fur that I believe are probably nits (I think that is the proper name for the eggs?). I have not yet seen an actual creepy crawly thing.

So I was wondering what is the best way to treat it that doesn't cost too much? I did a search, and Frontline spray was recommended a lot, but that is not cheap and I can't find it locally. Ivermectin horse worming paste was also recommended for rats, but at a dosage of a rice-sized bit per rat... I'm not sure how much to give to mice. Some people report success with PAM, others report it caused neurological problems.

I'd like to use PAM if I can do it safely, since I have it on hand already. Who has used it successfully with mice? Is there a way to be sure it will be safe? I was thinking maybe if I sprayed the enclosure bottom only, where it would be under the substrate and they would come into little if any direct contact with it, but will it even be effective if I do that?

Suggestions?
