The mites that affect rodents are not transferrable to reptiles. Most parasites, both internal and external are host specific. Some internal parasites will use an intermediate host to infect another species (such as tapeworms using cattle to infect us, or invertabrates to infect reptiles). Ticks are a bit of an exception where external parasites are concerned, they aren't so discriminatory....I should hope that nobody every has ticks on any animals they have!
While that is true, there have been many documented cases of pet store employees or customers transferring reptile mites (and other parasites) to rodents through not washing their hands between handling different animals. The mites aren't living off the rodents, they've just been transferred there.
Then the customer brings the mites home where they jump to an actual reptile host instead of just clinging to a "ride" as they had been doing.
