This won't make your ice cream invincible, but it's enough to keep it fresh for a little bit longer. Ice cream placement within the freezer also can make or break ice cream. The freezer, much like an oven, has a temperature control, but some spots are warmer than others.
Also most millipedes are nocturnal. They are generally speaking harmless but most species have a series of metathoracic glands which produce a repellent substance which they can exude when they feel threatened. In some larger species this fluid can be corrosive and cause blistering of the skin in large doses.
What eats a millipede? Millipedes are preyed upon by a large range of animals, including  reptiles, amphibians, birds, mammals, and insects. Shrews, toads,  and badgers will eat millipedes.
