Roach Bedding Chow is comprised of fine-ground alfalfa, Scottish oats, and partially ground non-medicated poultry feed. I use it as a 1-inch edible substrate in my dry species of roaches; Small roaches will burrow into it, and have dinner! It is 1/3 of the cost of Cricket Crack and Bug Buffet, and is an inexpensive way to feed large colonies.
