I heard you're supposed to kill the deformed darkling beetles that pop up. Well, so that they won't be a waste, can I feed them to my leopard geckos instead?
I tried feeding one to my previous leo. He didn't look twice at it. So I mashed the beetle and put some of the guts on his nose, to entice him. He gave me a terrified look and rubbed his nose against my arm to get rid of the guts/smell.
So, no, I don't think they like the taste very much.
