Fly maggot (likely a housefly larva)

Develops in moist, decaying organic matter, garbage, manure, or contaminated food; this one appears to be indoors.

Feeds on decomposing organic material and microorganisms in it.

Legless, pale larvae; mature maggots often leave their food source to seek a dry place before pupating. The image does not show enough detail for a certain species identification.

Maggots are harmless to bite, but houseflies can spread pathogens by contaminating food. They also help break down organic waste.
