My Adult Worms Seem to be Dying
2 mating worms
I have a flow-through bin up off the ground that is 29" wide x 41" long x 22" high. It has a hinged lid. I bought 1,000 Red Wriggler worms to start. Initial bedding was compost from my 30" round compost bin. I originally fed mostly table scraps, tea grounds, egg shells, spoiled lettuce, and coffee grounds. I soon started adding partially a composted horse manure & wood shavings mixture.
A small quantity of worms was introduced into by compost bin a couple of months before I bought the 1,000 (long story). To my surprise, the worms thrived on the raw horse manure/wood shavings that I dumped into the bin. These worms end up, a little every week or so, in my flow through bin. But a week later, I see very few large worms in the flow-through bin. I have lots of baby and adolescent worms, but few adult. This has been going on for a couple of months.
I had centipedes, but seem to have gotten rid of them; and it seemed they would have eaten the smaller worms anyway.
Moisture & pH are fine. I live in the San Francisco bay area with moderate climate and the bin is in the shade. I have never seen a worm on the side of the bin. There is 10" - 12" of air space under the closed lid, which gets opened multiple times a week (and it is not airtight).
