According to Snakes of the United States and Canada: Keeping Them Healthy in Captivity by John Rossi, Worm Snakes are difficult to maintain and rate a "4" on the a scale of 1 to 5 (with 5 being the most difficult).

Worm Snakes are rarely observed eating in captivity because they are extraordinarily shy and normally eat their food under surface cover. It is recommended that these snakes have both a thermal and a moisture gradient in captivity. The preferred food of this snake is earthworms (though they do eat slugs). I have never heard of one eating crickets.

I've found Eastern Worm Snakes inthe Carolinas, but in April I found my first Midwest Worm Snake under a rock near a lake in Ohio (pic below).
