Can fleas survive on humans?

If your home is infested with fleas, you may wonder if these pesky insects can attack you too. Theoretically, fleas can actually survive and even reproduce on a diet of human blood alone because our blood contains all the essential components that fleas need to survive and reproduce. But under normal everyday conditions, fleas do not live on humans. Fleas mostly prefer our pets as hosts. However, this does not mean that fleas will leave us completely. This blog explains why fleas can’t live on humans for long, even in your hair, but they can still bite humans.

Why don’t fleas live on humans?

We have three different types of fleas found in the UK, the most common being the “cat flea”. Don’t go by the name – they both happily feed on dogs and cats. These fleas like their hosts like fur animals. There are other types of fleas that can survive on humans, but these are much rarer. Fleas are fascinating creatures with a diverse range of hosts. While they often prefer furry animals, they have adapted to thrive in various environments. Some species of fleas can even be found on birds, showcasing their incredible versatility. Understanding the behavior and habitat preferences of fleas can help in developing effective strategies for managing and preventing infestations. Maintaining good hygiene and regular grooming of pets are essential steps in keeping these pesky parasites at bay.

Cat fleas prefer a hairy host because they burrow into the animal’s fur and cling to it when your pet moves. Humans have much less hair than fur, making it much harder for them to cling on if they jump on us, and they’re easily dislodged by a scratch or bath.

Human blood is also not as nutritious for fleas, and they cannot produce as many eggs on a human blood diet. Breeding is also very difficult without the protection of fur, so fleas quickly leave us and jump back in search of a more suitable breeding environment – ​​such as your dog or cat.

Can fleas live in human hair?

Fleas don’t live on humans because we don’t have fur, but what about our hair?

Although fleas are known for their long jumps, our heads are usually a bit beyond their reach. And they can jump out when you’re lying in bed, but even if they do get to a person’s head, they usually don’t stay there very long.

Human hair is not as dense as animal fur, so it is still difficult for it to cling. They also do not provide adequate protection like the fur of your dog or cat.

These bites are commonly found on the lower legs, ankles, and feet, but can also appear on other parts of the body if the infestation is severe. If scratched excessively, the bites can become infected, leading to more serious skin issues. It’s important to keep the affected area clean and avoid scratching to prevent further complications.
