I sure wouldn't feed them to my snakes- as jmcrook said, it's the parasite load I'd be concerned about.
You might ask around -if there are any snake rescuers around you, THEY might want wild mice to help get a finicky wild-caught snake to eat in captivity- since wild rodents do smell & presumably taste different from domestic ones, & some snakes ARE known to care about that.
But otherwise, I'd let the other hungry wildlife take them off your hands. Not literally, of course. But coyotes & birds of prey would certainly enjoy them, just saying.
One thing: wild rodents do pose health risks to YOU too, so keep the handling & your exposure to a minimum, and be sure you wash your hands as if you'd been hugging a COVID patient.![]()
