With 3 brothers I"m personally familiar with mealworms, as well as frogs, turtles et,al. And my own small Caiman alligator.
Bug barn? I think I need one as a very young Millipede ran across behind my kitchen faucets.. and when I moved the wooden crate to it to put outside - I squished it. I hate killing things.
But do tell how to build a jug barn. Is it an aquarium???
You saving a frog balances out my killing a Millipede. I hope.
