Hello

worms need it cold and they need to be kept in dirt that's damp enough, not to stick to them
there's a lot of good info here:

If you are adamant about not feeding dead (frozen/thawed) mice, then I would suggest you feed frozen/thawed fish. As others have stated, earthworms are not a good staple food, as they are very watery and are somewhat laxative in nature for the snake.

Frozen worms are a mess, frankly... and keeping a colony of live earthworms is normally done outdoors, which means you cannot access them in winter anyway, as the ground freezes and they hibernate below.

Fish should be those species that do not contain thiaminase, which is an enzyme that digests the vitamin thiamine, and is contained in some fish.

I used to feed a fish-only diet, and I found that bait store minnows and rosy reds from the pet store worked well. I also found that freezing them and thawing them was best for my snake, as this killed any parasites that fish might carry.

Finally, I found that on a fish diet, my snakes were never quite filled-out. They remained more slender than I thought was best. And that finally convinced me to add frozen and thawed pinkies to their diet. This has produced a better nutrition for them.

To thaw either pinkies OR fish, I take them from the freezer, and insert them into a jar of scalding water. They thaw in seconds (fish) or minutes (pinkies) and can be fed still slightly warm.
