Here's why you might think that fleas are more common on animals:
* Host preference: While fleas can bite humans, they prefer to live and breed on warm-blooded animals like dogs, cats, rabbits, and rodents. These animals offer a consistent source of blood meals and a suitable environment for flea reproduction.
* Lifecycle: Fleas spend most of their life cycle off the host, in the environment. They can easily jump from animal to human, especially if the animal has fleas and is in close contact with humans.
* Symptoms: Flea bites on humans are often itchy and can cause allergic reactions, but they don't usually cause the same level of infestation or health problems as in animals. This may lead to the perception that fleas are not as common in humans.
It's important to note that flea infestations can be a serious problem for both humans and animals, and it's always best to consult a veterinarian or healthcare professional if you suspect a flea problem.
