Tiny Ringneck snakes eat mostly earthworms; but again, you have to be sure that the earthworms you buy as food are not contaminated with pesticides.
(I've never had one, and probably most are WC. They are shy, secretive snakes.Here is a link to a caresheet for these little guys:
CHS Care Sheets - Snakes)
I've found that feeding frozen/thawed (warmed up) mice and rats A LOT easier than keeping crickets around as food for snakes -- as they only eat once a week and the crickets need to be well fed and nutritious. (creepy

)
You can order frozen mice and rats from RodentPro and keep them in a sealed container or bag in the freezer and thaw them out in warm water when you need them.
There is NO need to feed a snake live mice or rats -- it's actually EXTREMELY dangerous.
Captive born cornsnakes are a good choice of a starter snake. They eat well and usually are very easy to handle and care for. They also come in a HUGE variety of colors (morphs). But they need to be fed mice.
