i found trails of casting all along the sides of my bin today. i guess the worms were upset about being transported to a new home and were trying to get back to where they came from, got to the lid, then turned back around and snuggled back up into the pile they were dumped in. the piece of newsprint i used to cover them up with was very damp. i don't think i will ever have to spray the inside of the bin again. it seems like the moisture holds exceptionally well in plastic.
i threw a tea bag in there, underneath the newsprint. i poked around the vermicompost to see if they had burrowed down yet, and there were still a lot of worms in there.
p.s. my boyfriend is really sick of hearing about worms.
