Advertisement I was looking through my cabinets and found that the flour was absolutely infested with tribolium castaneum. I saw the larvae wriggling around in there, and considering I only keep small spiders (crab, jumper, lynx etc) I thought they would make good feeders and set them with the now ruined flour into a tub. I've had success using worm-like prey for all of my spiders, so I know they won't just turn it down, it would be an easily sustainable colony that I could use as a food source, even if the full grown beetle is useless for these spiders. The local cricket population is too random in size and number to be used reliably - these would be much more efficient. Are there any health concerns with them and the spiders/tips and issues with keeping them? I want to be sure before i try, and I can't find anything about them being used for spider food so any and all help is appreciated, thank you.
