These are the 4 bins that I had put what turned out to be mostly dead worms on. After cleaning off the dead ones, the mess left behind - despite me trying to get it all - attracted swarms of fruit flies.
So I sprayed with dunk water, then went through the bin SLOWLY and picked out the few surviving worms - about 60 out of over 2,000. Now I have them out in the sunshine for the day - 93⁰ later - and going to bake them to death. Talk about a super fast dry down! ;)
