No Mess Saves valuable supplements Specially designed edge ring prevents escape Natural look Easy to cleanMealworms need to be contained when they're placed inside the terrarium. If not, they will quickly 'escape' by digging their way into the substrate. There they will remain hidden until they can metamorphose into an inedible beetle. More likely, they will simply die, their decomposing bodies creating a banquet of harmful bacteria. The Worm Dish prevents mealworms from escaping, while allowing them to remain visible to the terrarium inhabitants.

Completely useless product. The removable lid allows the worms to crawl out. Terrible quality.
