Hannahkat and Nadine, Quite by accident I found that a paper towel roll does the trick for collecting worms. Just push it down into the substrate being careful not to get to much bedding into tthe tube. Leave it for a couple of days(one day). then empty contents into seperate container. I got a nice haul of worms for my girls the other day this way. The worms don't seem to drag much bedding into the tube.
