I have two worm farms running. The one I bought, the other home made. The one I bought has been up and running for about a year now and the second one for about 4 months.
I have, in the past 2 months, noticed that my worms, in both farms have a tendency to escape into the bottom bins and end up in the worm tea. Some of them drowned but I check on a daily basis now and most days I recover worms from the bottom bin.
It stated with the new bin first and I thought I had made to many holes in the bottom. I've been contemplating taking everything out and placing a piece of mesh (Shade cloth) on the bottom to still allow the liquid to drain but the worms will not be able to escape.
The bins get some afternoon sun. Could it be that they heat up too much?
I cover the surface with cardboard or newspaper which I keep moist by spraying it with water every morning.
Why is this happening? Are my bins overcrowded or am I doing something wrong?
