Flea larvae primarily feed on what substance?

Flea larvae primarily feed on organic debris, which includes a variety of substances, such as organic matter found in the environment where they live. This organic debris can include shed skin, hair, feces from adult fleas (which contain dried blood), and other decaying organic materials.

While dried blood might seem like it would be a primary food source due to its nutritional value, flea larvae do not directly consume blood but rather rely on the decomposed organic matter that includes remnants of blood and other proteins. This diet allows them to grow and eventually develop into adult fleas. Understanding this feeding behavior is crucial for controlling flea populations effectively.
