Fleas are opportunistic parasites primarily residing on animal hosts. Their ability to transfer and survive on humans, serving as a temporary transportation method to a new environment, is limited. The period fleas remain on a human is short, typically only seeking passage rather than long-term habitation.
Understanding the transient nature of fleas on humans is crucial for effective pest control strategies. It informs preventative measures, such as treating pets and environments simultaneously, to disrupt the flea life cycle and reduce the risk of infestation across multiple locations. Historically, flea control focused solely on the primary host, but recognizing human involvement in transportation necessitates a broader approach.
