The larva feeds on dead or necrotic tissue for 3 to 10 days, depending on temperature and the quality of the food. During this period the larva passes through three larval instars . At a temperature of 16 °C (61 °F), the first larval instar lasts about 53 hours, the second about 42 hours and the third about 98 hours.

They are commonly found in several household products, including food packaging, toothbrushes, cosmetics, car parts, tools, and toys. One study found a link between phthalates and wheezing and eczema.
Flies undergo complete metamorphosis; the eggs are often laid on the larval food-source and the larvae, which lack true limbs, develop in a protected environment, often inside their food source. Other species are ovoviviparous , opportunistically depositing hatched or hatching larvae instead of eggs on carrion , dung, decaying material, or open ...
