Due to the high body temperature of fleas, they cannot stay long on humans. They cannot breed on humans too, so they need to find animal hosts or else, they cannot increase in numbers. Studies have shown that female cat fleas can stay on humans for only 7.4 minutes, and male cat fleas can only stay for 4.4 minutes.
