Hello all! I'm a new member on this forum, and while I know this may sound like a ridiculous question to some of you, I would like to know what products are safe to use on hissing cockroaches, in order to give them them very small identifying marks so I can tell one from the other. I'm thinking of using a very small identifying dot. I've thought of using a Sharpie marker as it says upon the marker that it's nontoxic. Still, I don't know whether that means it certainly wouldn't harm an insect. I only have a couple of roaches and they're new to me... After one molted, I can no longer distinguish them from one another. Thanks for any help you're able to provide!!
