Paint blocks of wood with glow in the dark paint, then have some fun with black paint for their faces. OR Paint the wood black and the faces with glow in the dark paint so the eyes and mouth "float in air".
get 2 brown paper bags and cut to desired height. Cut one bag into strips (all sides but the bottom). Put treat in uncut bag, then wrap cut bag around that. use a carmel apple for the treat and have the stick in the apple double as the broom stick.
