Hey brother, I used Chicken "crumbles" food from a local feed store.
50 lbs for like 13 bucks, it worked great, and it will last FOREVER
Reason Im asking is most know as bottom of your rodent food bags, theres like a pound of food in dust. Rather keep throwing that away, figured let the dubias eat that on top of the fruits and veggies.
Since im usign 23% Rodent Blocks should be perfect for them.
