Q1: Can cat fleas bite humans and live on human hair?
A1: Cat fleas readily bite humans, targeting ankles and lower legs to leave small, intensely itchy red welts surrounded by a reddish halo. However, they cannot establish breeding populations on human bodies. Humans lack the dense hair cover fleas need to hide, and human blood does not supply the precise nutritional profile adult females require to sustain egg production.
Q2: What is the visual difference between a flea and a tick?
A2: Adult cat fleas are narrow, laterally flattened insects measuring 1.5, 3 mm with six legs and remarkable jumping ability. Ticks are eight-legged arachnids that move slowly, crawling rather than jumping. Unfed ticks are dorsoventrally flattened (compressed top-to-bottom like an apple seed) and swell into grey, marble-sized spheres as they gorge on blood.
Q3: Why do I still see fleas after applying a veterinary topical treatment?
A3: Modern veterinary treatments kill biting adult fleas quickly, but they do not eliminate pupae already resting inside your carpets. Pupae can stay dormant within resilient, debris-covered cocoons for weeks or months. As ambient vibrations and body heat trigger them to hatch, these new adults jump onto your treated cat, dying within hours of contact. Complete home eradication typically requires continuous treatment for 8, 12 weeks to break the full cycle.
