Rodents can pass on hook worms and pin worms to a BP. Worm infested BPs tend too go off feed and is just a pain in the butt to deal with and treat.
It's just better off not feeding wild animals to the snakes. Not to mention the mice who have been exposed to rat poisons and chemicals.

Why expose your captive snakes like that when there are other better options of food?


I personally de-worm my rat colony annually, so I know they're clean. I don't fancy parasite infested snakes.
