I'd just find a quiet corner and keep the feeders indoors for the winter months. They can burrow sure in those enclosures but unlike out in nature they don't have deep leaf litter, snow, somebody's basement or attic, whatever as a natural insulator. No amount of store bought bedding will, in my opinion, really do that job correctly. If you are raising feeders to feed your snake's good quality food and save a few bucks, then it doesn't make much sense to have them dying off or not putting on the weight you want efficiently.
