Hello Evanmancini2011;
I've found that my Tetramorium colonies eagerly take sow bugs and pill bugs, just split them in half while frozen. They're easy to raise but I catch enough of them under a wet board in my garden for the whole season.
I would be remiss if I didn't point out that Tetramorium ants will gladly take a variety of meat products as well as insects. I feed mine cooked chicken and liver, cooked turkey and liver, raw ground pork, salmon, canned dog food, and cooked egg yolk. Below is a link to a thread about a feeding experiment I did with a Camponotus colony that received only meat products for the entire season. Much of what I wrote about the Camponotus colony in my experiment holds true for my Tetramorium colonies.

My father always said I had ants in my pants.
