Cat fleas can travel on humans and cause discomfort. TRAVELS.EDU.VN provides expert advice and solutions to manage flea infestations effectively. Addressing concerns about flea bites, transmission, and prevention is crucial for a flea-free environment. Explore preventative measures, flea control, and integrated pest management to safeguard your well-being.
1. Debunking the Myth: Can Cat Fleas Live on Humans?
Yes, cat fleas (Ctenocephalides felis) can indeed live on humans, although they prefer furry hosts like cats and dogs. Despite their name, cat fleas are opportunistic and will feed on various mammals, including humans. Adult fleas require blood to survive and reproduce, while their larvae thrive on organic matter such as dead skin cells. This adaptability makes it possible for cat fleas to infest homes with or without pets, debunking the myth that they only live on cats.
