Yes, you definitely are, and I hesitated to go that route for a long time because of it. I finally did, for simplicity's sake. What I used to do, is set up a new container, and transfer as many as I could to it manually. Then everyday, I would transfer the worms that came to the surface...and so on. Eventually I would end up with a container that appeared to be nothing but dust. But if I left it a couple of months, it would repopulate with worms from all of those eggs (I never could figure out what they were eating to get as big as they did in a container that appeared to be nothing but fraas, but apparently they found enough). The problem with that method is that a) it was an extra container sitting around most of the time and b) by the time I finally got them all transferred from Bin A to Bin B it was time to start all over. So I decided to go simple and not worry about the eggs and babies, so that I can really only have one container. It does mean my population has to start over every three months, though so if you want a continuous supply, you should probably count on multiple containers.HEChicken-that cleaning part is what I'm trying to figure out. I'm not sure how I'm going to do it. I am planning on using the "one container" method just for simplicity. If you scoop as many worms, pupae and beetles out as you can to put in the clean bed, aren't you throwing away all of the eggs and many of the newly hatched, tiny worms?
Funny story though....last spring I was digging a hole in my vegie garden to plant a seedling and came upon a large mealworm. I think it must have grown from an egg left in the fraas when I dumped it out there once the year before and survived the whole winter in the freezing ground.
