Tenebrionidae larvae of a beetle

larvae of a beetle in the family Tenebrionidae

5815   I found these in a light hanging from the roof. How would they get there? Is this something I should be worried about? And please tell me what they are.

These appear to be the larvae of a beetle in the family Tenebrionidae, which includes nuisance pests such as the yellow mealworm. They are unlikely to cause any harm in their current location, but you might want to periodically check any areas where you store grains, seeds, etc. for any signs of infestation.
