Where do female fleas lay their eggs?

Female fleas deposit their pearly white, oval-shaped eggs either directly on the body of the host animal or within the host's nest or habitat.1

Once laid, these eggs develop into larvae that rely on organic debris—such as dried skin, mites, or excrement—found within the nest for nourishment. In some species, such as the European rabbit flea, the timing of egg-laying is precisely synchronized with the host's reproductive cycle to ensure the offspring have a suitable environment for development.1
