- Inflammation of the skin
- White specks of dust on the rat's hair follicles (these are the mites and they may resemble ticks at first check)

Clean anything that can harbor the mites.^{[6]

Research source} Do this 24 hours after the treatment is administered. The treatment will kill all the mites on the rats but will not kill mites or unhatched mite eggs in the rat's environment.
- Get rid of anything wooden. Such items are almost impossible to disinfect, and the mites can hide in the wood.
- Clean everything else with a bleach solution. This includes the rat's cage.
- Wash any fabrics in or around the cage, and put them in high heat in the dryer. Ideally, don't put any fabric in or near the cage while the rats are being treated.
- If you need to disinfect human areas such as beds and furniture, use rubbing alcohol (isopropyl alcohol) in a spray bottle. The benefit of using this is that it kills mites on contact but volatizes quickly.
- Other means for catching mites include sticky glue traps or clear sticky tape. Vacuuming is effective provided you dispose of the bag outside (or thoroughly clean a bagless version), or you can try vacuuming with a filter such as a handkerchief inserted into the vacuum tube and then transferred to a sealed tube or alcohol to kill the mites.

Isolate the rats. Put them in a part of your home where they are least likely to come in contact with any mites in any stage of their life cycle.
- Keep them away from any other pets. These mites can live on other pets for about two weeks, but will die when they can't get to the rats. If there are any mites on your other pets and they come in contact with the rats, they'll just jump right back onto your rats and continue their life cycle. Ensure that other pets cannot get into the space where you're keeping the rats.
- It might be a good idea to keep your rats somewhere different than their usual spot (which might have mites hanging around) and somewhere without carpeting.
- Keep the rats isolated like this throughout their treatment period, until the mites are gone.
Again, sanitize everything in and around the rat cage 24 hours after treatment is administered. This is to kill any remaining mites and eggs.
