Not one.a dozen had jumped out into the moist coco coir bedding in the tray under their tub! That’s where they were going in such a hurry! I put them all back in their tub saying bad worms! I hope there aren’t any left outside the tub. One was on floor and I almost stepped on him! I have the lamp on and all is quiet. On the whole it wasn’t too stressful.Get back in there wormie!
