Can Fleas Live in Human Hair? Explained 2022

When you see your pup sitting in a corner and scratching his ear or biting his skin obsessively, you may start to worry that he’s got fleas. But what if those pesky fleas have set up shop on your head? Can fleas live in human hair?

 

Fleas can set up camp in animal fur, including human hair. While humans aren’t their preferred host, fleas will happily make themselves home in your locks if they get the chance. But fleas can’t survive long enough in human hair because of lower PH levels and lack of proper temperature.

 

This guide will discuss everything you need to know about fleas in human hair, including how they get there, what to look for, and how to get rid of them.

How do fleas get in human hair?

 

Fleas are flightless but still able to jump long distances. They can hitch a ride into your home on your clothes or pets, and then they’ll start looking for a place to live. Many people think humans can’t get fleas because they are tall and have smooth skin, but that’s not true!

The jumping power of a flea is impressive. They can jump up to 200 times their body length, about 7 inches. That’s like a human jumping over a 14-story building!

Once a flea is in your home, it will start to look for a warm body to live on. That could be you, your family, or your pets. If you have a pet, the flea will probably jump from them onto you.

Can fleas live in human hairs?

 

The short answer is no; while they can not jump over humans and set up shop in your hair, they can’t complete their entire life cycle there. Her is a detailed answer to this question.

Fleas are flightless insects that live by piercing the skin of their host and sucking their blood. And they get the best of both worlds by hanging out in your pet’s fur. But can they also live in human hair?

While fleas can’t jump from person to person, they can jump from animals to humans. And once they’re on you, they can undoubtedly crawl into your hair. But that doesn’t mean they’ll be happy there. Below are the possible reason

  • Fleas need warm, humid conditions to thrive, and your head is not the ideal environment for them.
  • The grip of human hair is also not as firm as that of animal fur so fleas would have a hard time hanging on.
  • Fleas need a specific PH level(7 or above) and temperature to lay their eggs, while the PH of human skin is around 4.5-5.5, and our temperature is lower than that of animals.

What do Fleas need to survive?

Fleas demand three blood meals daily and can survive for more than 100 days if they are well-fed. For living their best lives, fleas need:

  • Warmth temperature: Cold-blooded fleas must have a warm temperature to function correctly. If the temperature is too cold, they will enter a state of dormancy called torpor.
  • Humidity: A relative humidity of 50% is ideal for fleas. If the environment is too dry, they will dehydrate and die.
  • Blood: While female fleas can live off a blood diet, males cannot. A female flea can consume 15 times her body weight in blood every day.
  • PH Level: Around 7.0 is the perfect match for a flea’s needs. And if the conditions are too acidic or alkaline, it will irritate their exoskeletons.
  • Firm grip: Fleas can’t strive in an environment where they can’t get a good hold. A smooth surface like Teflon won’t work for them.

How to keep the fleas away from your hair?

When you scratch your head, ideas start flowing, and you feel more productive. But if your head itches because of fleas, that’s a problem. No one wants fleas in their hair!

Here are some tips to keep the fleas away:

  • Locate the entrance and block it: Your first step starts with blocking the entry of fleas into your home. Pets, cracks, crevices in the walls, and even second-hand furniture can be culprits. So if the source is a pet, groom them regularly and use a quality flea collar. If it’s coming from outside, use insecticide sprays around the perimeter of your home.
  • Vacuum regularly: Fleas love to hide in carpets, rugs, and upholstered furniture. So make sure you vacuum regularly, especially in those areas. And don’t forget to empty the vacuum bag afterward, so the fleas don’t just crawl back out!
  • Wash your bedding in hot water: Fleas love to lay their eggs in bedding because it is warm and humid. So get in the habit of washing your sheets, pillowcases, and blankets in hot water at least once a week.

Conclusion

So, we were talking about whether fleas can live in human hair or not. And we concluded that fleas need warmth, humidity, blood, and a specific PH level to survive. And our hair doesn’t provide them with any of those things.

But even though fleas can’t live in human hair, they can still crawl into it and bite us. So don’t take any chances, and follow the tips above to keep the fleas away!
