I totally threw all the innards from my pumpkin into the roach bins and they devoured it. My smaller roach species even ate through the seeds, which I didn't expect. I don't like pumpkin very much so I thought it would be a waste just to throw it out.
I did only give it to the roaches and not the crickets, though. I wasn't sure on how great it was for the chameleons so I just gave it to the breeding colony insects and not anything that I'm feeding from this week. From Sandra's blogs it seems as though they're not great but not the worst thing you could feed, either. And who can pass up on free gutload?
