Sorry, Rita, I'm sure you won't like my method and this is why I wish I had got a stacking system, but I didn't know about them when I was starting out! What I do to clean my bin is dump the whole thing out on a tarp on the floor of the garage. (I guess you could do this out in the yard also, just curl up the edges of the tarp to keep the lil worms from escaping. Then I make piles with the contents, oh probably about 20 piles. If it's bright enough when you do this , the worms will go to the very bottom of each pile. The pile is like hand size in width and 6" tall. I scoop up an individual pile and pick all the worms from the bottom and toss them in to one pail. After picking through the rest of that pile for anymore worms I toss that into a different pail. I try to get some of the eggs into the worm pail too, but this job is so tedious that I usually just let them go in the compost bucket by the end.
At some point in this procedure (to break up the monotony of worm picking), I go and clean out the bin itself, hose it down, fill it up with fresh bedding, a little soil, water. I don't put any food in for a few hours or overnight to let them get settled.
I don't keep any of the food from the bin, I start the clean bin fresh. If there is anything that has not been broken down all the way left in the bin, I throw it out in the compost pile out back.
Some of the good castings (about 1/2-1 gallon) I put in a separate 5 gallon pail and add water to it for compost tea.
I hope this helps, I'm doing my bin today! :p
One really good thing about this method, is you really get to know your worms and what is going on in the bin. See if you've got alot of reproduction going on, etc. etc.
