I'm regularly collecting final stage larvae now. They drop into a collection bucket so I don't have to dig them out of the scraps. They are dry and seem to be very clean. I have no hesitation to reach in and grab some, and in fact it's more pleasant than handling worms because there isn't any slime. The BSF try to crawl away but it isn't as dramatic as it is with worms.
All I need now is a pond full of fish.
On a side note, the BSF always eat soft food like fruit or dairy products first, but one exception is coffee grounds. Every morning I put the used coffee, filter and all, into the bin and the larvae head straight for it.
