I have read that it would not hurt mantids and tarantulas. Are you sure it will not hurt roaches? I ask because it is a little bit hard to believe haha. Do you use it a lot on insects and stuff?You could use superglue. It won't hurt the animal but it won't come off very well either.
It is used to seal wounds on arachnids and insects as well as attach delicate marine coral frags to rocks.Isn't that like crazy glue, which smells so bad I can't see how it would be safe for insects.
