lol, cheese balls or pretzels? I have quite a few of those. It is easier to cut out the label and screen it than try to remove all that sticky, right? Also better for ventilation.
That's the same containers I used. I took the label off without leaving any residue. You just have to go slow and steady with even pressure and it pulls right off cleanly. I also made a large cut-out on the side like that except mine is a door that I can open and close. I find the side access door is much more convenient for putting active prey in because they tend to go up. Plus I can get in there for cleanup, misting, and whatnot without disturbing the mantis (unless the mantis is on the door of course but then I can open the top) or letting the prey out.
I used air conditioning filter material instead of normal screen because it provides good air flow but fruit flies can't easily get out of it (crickets sometimes eat the material though).
I made a little latch out of the extra plastic, bent it into shape and hot glued to the side. The door is just the filter foam tied to a coat hanger which is bent to the shape of the container. All my foam pieces are just held on by wire which makes it easy to replace if needed.
Edit:
I also lightly sand the top clear part of the container (hard to see in picture) just to rough it up a bit so the smaller mantises can grip better on that top corner where it curves over since prey tends to hang out there.
