How many worms do I need to start my composting bin?

We use 18 gallon plastic totes, which we fill about half way with horse manure, peat moss, veggie scraps. How many worms you’ll need to start in each specific bin? Generally around 1 pound, which is roughly 800 to 1,000 worms, for most composting bins this size. Worms self-regulate their populations based on the space and amount of available food, so you won’t have to do anything to manage their numbers. Worms can live for about a year in the worm bin. When they die, their bodies, which are about 90 percent water, will become part of the compost.
