Okay, So this is what I am learning. If you bother to sift you will only get poop and eggs as they are the only stuff small enough to pass through most sifters. Then put all of it into bran to let new babies grow. The poop won't hurt anything and you don't want to throw out the next generation. If you make a sifter out of a screen that has bigger holes than your sifter you may sift out the frass or cast off skins, but you may also lose some of the smaller meal worms in the process, so it wouldn't be worth it. So don't bother to sift! Also I saw someone's foto with a good idea. They put the wet veggies on top of newspaper or paper towels to absorb the excess wetness and the mealworms had no trouble crawling on top of the paper to get to their moisture source. Can anyone see anything wrong with doing that? I'm waiting for mine to come in the mail right now. I've got my container, a 10 gal. aquarium full of bran and oats with a lid. So I'm figuring it out! : )
