I was apparently unclear......
I meant to say mites(reptile) can live ON rats. This does not mean they are feeding on the rats. They basically are using them for transportation of sorts.
And also as stated, there are mites that do live off of/on rats. Hence why I asked if they were mites or fleas.
Mites are easily killed, fleas are not.
Fleas will avoid anything that eats a good bit of garlic. Mites can be killed using preventamite or using a low dose(really watered down)of "RID" does the trick also if applied to their environment..
I wouldn't recommend using any type of of flea spray if you are unclear of what you are dealing with.
fleas are tough creatures....
