Then it's a good thing you found US

Give the worms away to someone who goes fishing....

where are you located? maybe able to direct you to a good source of food.

I would try a cut up fish fillet from the grocery store, Tilapia and Salmon are good economical choices, and most garters will eat it right up with little effort.

I have a few that require me to grab the chunk of fish in a pair of tweezers and show it to them.
