  • Question
    What size container should I use for catching a centipede or beetles?

    It depends on the size of your beetle or centipede. My millipede is about 7 cm so I put it in a 15-20 cm container. I suggest using a container about double the size of your insect.

    What do I do if I find a bug that's bigger than my container?

    You would need to find a bigger container that fits the size of the bug. If the insect gets any bigger, switch to a different container that lets your bug move freely. If you don't have a big enough container, do not try to capture the bug.

  • Question
    How do the bugs breathe without air in the terrarium? Do I just poke holes in the lid?
    Community Answer
    You can poke holes in the lid of your jar or cover your terrarium with a screen lid. Most terrariums sold in stores come with screen lids, but if you don't have one, you can cut the screen out of an old screen door and secure it over the top of the terrarium with some tape.

    Can I use wood chips instead?
    Community Answer
    It depends on what type of insect. If your bug was found in similar substrate, that should work fine.
