FACT: In one year two mature worms can produce 1,500 worms per year in ideal conditions

This fact may well be coming to fruition in my bin as the worm population continues to increase! Many sightings of worms not more than a few weeks old have been seen recently which is generally a good thing in my opinion because it means that the bin is fully-functional with new worms seen, organic waste being composted and worm castings being produced. If the worm population gets too big for the bin then I shall probably build an overflow bin.
