So do to a shipping error I received 1200 dubia roaches in 3 different packages so now my cricket pen I was using isn't going to work as well as it did. Could use some idea for containing them while possible retaining the usefulness of the tubes from the cricket pen.
I use an old 15 gal. fish tank with a screen top and also use a large plastic bin (sides are smooth so they can't climb out. I use the tubes from the cricket keeper also on the bottom and I use cut up egg cartons and recently used empty paper towel and bathroom tissue tubes. The tubes work really well and they seem to like them.
