They might have run away from home because you didn't feed them. Dig a hole and put in some green kitchen waste, shredded newspaper or shredded brown grocery bags and coffee grounds. Sprinkle a bit of that dried lasses if you have any left. Sugar will do if you don't. Wet everything down and cover that hole back up and they should come back home. Keep hole composting in that area you want to grow in so that they stay around.
