I'm not sure if whole oats will work either, it might though.
I have some concluding remarks about breeding these wax works.
I started out with 25 worms and I ended up with tons of worms, but, where I failed was that I didn't have enough ventilation in the canister and I got tons of moisture which caused the substrate to start molding from the outside in. I decided to end my experiment lastnight and savage as many worms as possible. The worms, as they grow, make a ton of webbing and will migrate to the top of the container. They will also make the substrate into giant web/substrate ball for them to live in. They make these web cacoon type caves that the individual worm will live in. It was a real mess getting the worms out of the web/substrate ball and to make it worse, the outside edges were mucky/moldy. Separating the worms from the web ball was not for the weak stomach
I did manage to get a lot of waxworms (100) but they were rather small (the size of medium to large repti worms) because I had to end it early because of the mold issue. I would have had a ton more but a lot died from the moisture/mold issue.
If I do this again, this is what I would do:
1. make the holes in the lid bigger for more ventilation, in which case you would have to use the nylons to prevent the moths/worms from escaping.
2. use heat right from the start (85 degrees) to make the process go much faster.
3. figure out an easier way to separate the worms from the substrate easier. It wouldn't have been that gross if I didn't have all the mold to dig through, but it's still a pain digging through the substrate/webb ball.
