No one wants to eat wax but sometimes you just don't know. Go into a grocery store and try to buy an apple that isn't shiny. You probably can't. They cover all apples in wax because they know it will attract customers. People are naturally drawn to shining and glowing things.
So next time peal an apple before you eat it. Save the apple peals for your worms. Red worms love apple peals & the core. Plus the shinny wax may be toxic to human won't do any harm to the worms.
