What do flea larvae primarily feed on?

Flea larvae are opportunistic feeders that primarily consume any organic matter they can find, which includes a range of materials such as organic debris, dead insects, and the dried fecal matter of adult fleas that is rich in undigested blood. These larvae thrive in environments where they can find suitable food sources, often in areas where pets live or roam, as adult fleas feed on blood and expel waste that larvae can then consume. This diverse diet allows flea larvae to develop effectively before pupating and emerging as adult fleas.

The other options are less relevant to flea larvae’s feeding habits. For instance, while plant materials, processed food, and human hair may not provide the necessary nutrients for flea larvae, their consumption of a broad range of organic materials is what supports their development. This natural adaptability in their feeding behavior is key to their survival and proliferation in various environments.
