What do larval cat fleas predominantly feed on?

Larval cat fleas predominantly feed on detritus from the environment, which contains organic material such as dead skin cells, hair, and the feces of adult fleas. Adult fleas consume blood, which they then excrete as feces that becomes a food source for the larvae. The larvae use this fecal material, rich in digested blood, as their primary source of nourishment. This method of feeding enables them to thrive in their environment, as they can find sufficient sustenance in areas where adult fleas have been active.

Understanding flea biology highlights the importance of managing adult flea populations effectively, as controlling them will subsequently impact the availability of food resources for their larvae and help disrupt the lifecycle of these pests.
