Anyway, let me show you what I mean.
Here they are, just beneath the surface of the bedding material. As long as the material has enough moisture content and it is dark enough, this is where they like to be. I have just brushed the top of the bed with my hand to expose these worms.
Here I have added shredded newspaper to the bin. I have been using manure all summer because it has been so hot and the manure was well composted. This meant that the bedding wouldn't add to the heat already building up in the bin. But now the bins are starting to cool down, back into the 70's and a nice layer of shredded newspaper is an appreciated change for the worms. They move into it overnight.
Within 6 days this is what the bins above look like.
So now I need to go out and feed my worms. Until next time happy worming!
