While I was moving the contents of the drawers, I noticed that the worms whose eggs I sifted on April 10 had lots of dust (frass) in it, so I decided to sift them and give them some new bedding. This sifting didn't take as long as the first one, since the worms are more uniform in size, and not as many tiny ones went through the sieve.
I have seen quite a few moths flying in the house....the kind that get into bird seed, and I've found a few in my worm drawers. I worry that they will lay their eggs in my worm bedding. I doubt that they will do any real damage except make the bedding "webby", but I'm trying to find out which container of bird seed they're coming out of, so I can get rid of them.
My next project is to go through all my blog entries and sticky notes and make a chart of what I've done when to each drawer.
