Does anyone use a Wormbox for composting. Mine is inside not in the garden but I didn't know where else to put this thread. I have had mine just about a year and all is going well, lots of worms, all seem happy but when I check there are always about 20-30 worms in the sump tray. They won't have any food down there and when I have researched online it says they will climb back up to the higher trays to get food but I'm not too sure they can get up there. I had put cardboard in the bottom of the last actual tray to stop them falling/crawling down but they still manage to get down. Can they get back up? I don't want them to starve in the sump tray so every couple of months I gather up all the strays and put them back in the top tray. If anyone knows if this is normal or what I am supposed to be doing please let me know.
