Saw a tiny orange bug moving on my pet mouse. Could it be a mite?

Updated On September 23rd, 2025

Hi. So I have a pet mouse, she’s only a hopper and is very tiny. I was holding her, and I saw a little orange red thing moving kind of near her neck/back area. I only saw one, and she seems fine. She doesn’t have any of the symptoms. Just wondering if I should do anything.

Hello. You may have seen the common mouse fur mite. We can treat this with Revolution ( selamectin ) or ivermectin, but you will really need the help of a veterinarian, first to diagnose, & second to prepare a dose small enough to treat such a tiny patient. Thanks for using Petco Pet Education Center, formerly Petcoach.
