What If Maggots Are Crawling Out of the Bin?
Larvae sometimes leave their food source when they are ready to enter the next stage of development. This can result in maggots appearing on the ground around a garbage container.

Food dropped behind appliances
Pet-food areas
Forgotten potatoes, onions,
