Yeah, I know they're high dollar feeders. I thought the same thing til I had to clean that crap up. My gf was gagging when she saw the mess they made. She still makes fun of me about it a yr later. lol
Now I pupate a few worms here and there and I immed feed em off after they emerge before they can puke on anything. My big males will eat the moths but my females act like they are scared of them. lol
Check with Dave at Small Pet Feeders. His prices are reasonable you might save a few bux on your next order. He rears the blue form of horns.
