Can Humans Carry Fleas from One Home to Another?

The short answer is: YES – but rarely – bringing flea-infested clothes, bedding, and furniture like a pet bed into your home may spread fleas to the new location.

But a few flea species (like the cat fleas) will hitchhike onto humans moving from house to house. They’ll cling onto your clothes, shoes, skins, or the hair – using you as their live transit carrier. Can Humans Carry Fleas from One Home to Another

But humans & pets mainly get fleas from areas where they sleep and live. For example, a flea-infested pet bed may transfer more fleas from one home to another.

  • The human skin has few hair/fur compared to dogs or cats, and thus won’t be a suitable hiding place for the bugs. They’ll jump off to furry pets – but they may suck the human blood – for a maximum of 24 hours

We must not be fixated to examine all the small items that stick in our clothes when moving from one house to another.

So, flea repellents such as apple cider vinegar or coconut oil will help remove/ repel the hitchhiking fleas. See Also: Controlling fleas or their eggs

Can Humans Carry Fleas from One Home to Another?

Fleas spread through animals – practically flea eggs will fall from animal fur and feathers into the house spaces and the yard – and this allows fleas to spread. See Also: flea sprays your yard

A recent Interhost cat fleas transfer study resolved that between-host flea transfers are only 5-per cent and just 7.5-per cent of the fleas will jump onto another host in the same living space. 

Hence, flea eggs will the main spreading agents – as the pets and wild animals roam around the yard. The eggs that’ll land on some cool and moist micro will hatch – quick multiplication. 

  • Fleas will hide in different places in your house – and just like with bed bugs; fleas may be transferred by old shifting furniture. 
  • While moving furniture such as couches between rooms or houses, they’ll carry flea eggs, larvae, and pupas – these flea stages account for over 50-percent of the flea population. 

Therefore, for any rooms with fleas, avoid moving the furniture until they’re all treated. I recommend using borax for fleas or some diatomaceous earth on the flea-infested furniture. 

  • Avoid buying vintage or secondhand from a shady yard or dealers – you may also use steam-treatment. Treating the flea infestation will prevent allergies, skin irritation, and bites. 

How to Avoid Carrying Fleas to Your House 

It is practically impossible to avoid carrying fleas between rooms or homes. But we may take additional steps when we arrive at our residences or homes to avert the menace. 

  • For start, keenly and regularly examine your pets and spaces for fleas – check the pet’s sleeping and eating areas, plus remember to declutter barns and crawl spaces. 

1. Use Natural Flea Repellants 

There are homemade remedies that help prevent to exterminate fleas – like brewer’s yeast, rosemary, diatomaceous earth, lemon spray, salt, baking soda, coconut oil, and Dawn dish soap

Largely, these natural remedies (organic or herbal) are introduced into the diet or bathroom solutions – they’ll help repel the fleas from the clothes, fur, and skins

a. Essential oils

Suitable essential oils will effectively exterminate fleas including clove, lemon, citronella, peppermint (like the castile soap), lavender, and cedar. 

b. Vinegar or Lemon juice

You can create a spray or use a few drops in the bath solution – the smell of vinegar or lemon juice will repel the ticks and fleas. You may also massage the pet’s skin with 1/2 a lemon. 

For spraying, mix vinegar + lemon juice and water – then spray your pets at outdoor space. Some individuals also use apple cider vinegar, as a diet, adding it to the pet’s food. 

c. Betadine Bath 

You may bathe your pets using betadine (the antiseptic) solution as it’ll help kill fleas plus it’ll soothe skin allergies and flea bites – first, shampoo + rinse the fur off. 

Add 2 betadine drop into your water (about 1 litter) – the final solution should be similar to iced tea. Pour this mixture on the dog’s body and massage thoroughly. 

d. Garlic 

The Natural Vet’s outlines that small garlic doses won’t harm your dog. To control fleas, crush a fresh garlic clove – the fleas won’t love the smell.

You can add the garlic clove (crushed) into the dog’s food – this should be crushed ~ 15 minutes prior to adding food for a dog weighing 10-20 lb. 

2. Heat-Treatment 

Well, yes, heat treatment is effective against fleas and the flea eggs too. You’ll require to steam-clean your spaces prior to doing the vacuuming – continued vacuuming will even hatching fleas. 

Fleas won’t survive heat-treatment at temperatures over 35ºC, but some exterminators advise raising the temperature to about 49-56ºC. 

The hot airflow generated by the heat-treatment will get into the fabrics. Thus, upon arriving home, put the clothes into some dryer for washing using the highest temperature suitable for that fabric. 

But you can also use commercial flea-killers including Revolution, Frontline, & advantage

Here’s my Short Flea Story

I had just been transferred to my current job – 2 years ago. I landed in town to search for a rental house. All I can remember is that I entered many homes – some smelly and dirty as they’d had no tenant for a long time. 

  • As I went back to my host’s house, I started feeling itchy all over my body.  I noted the small bumpy and clumped up bites on my body. Sadly, I realised that I had carried fleas from my house, searching for a spree.
  • Well, I took a thorough shower and tried treating my clothes with a very hot water dip. The house had a massive flea infestation after this event.
  • Did you ever wonder why pest exterminators and vets wear scrubs instead of nice clothes as they work? See Also: flea bombs

Well, they don’t do this due to budget constraints – or to look cool or smart – but to avoid carrying dangerous pets and infections back to their house. After work, the professionals change the scrubs to avoid moving home fleas, brood, larvae, and faeces that could be a menace in another client’s house or home. 

Here’s the deal: According to School IPM flea control, Adult fleas will emerge from their pupal casing after 1-2 weeks but may stay dormant in the cocoons for few months, reliant on favourable conditions and food.

When you enter an unoccupied house, the vibrations, heat, and carbon dioxide you generate will cause the flea adults to emerge from their pupal stage. 

What Risks do Fleas Pose to Humans in the Home?

Fleas post significant danger to homes, pets, humans – besides being a nuisance. Severe flea infestation could also be fatal to your pets and other animals. 

  • In the U.S, the bugs are known to trigger flea-borne diseases such as Rickettsia prowazekii (southern states) & Bubonic plague (western states) – bacteria diseases that require antibiotic treatment
  • Fleas bites will also cause allergic reactions (and scratch bites) to the human or pet’s skin as the body reacts with the bug’s saliva – and this may lead to flea allergy dermatitis
  • Fleas may also cause tapeworms on humans and pets that ingest the fleas – you’ll see pumpkin seed kid objects in human pr pet faeces – consult a veterinarian or a doctor. 


It’s practically impossible to thoroughly and always check for fleas in your clothes. It’s even harder to limit the places your visit for fear of carrying fleas

To limit the number of fleas, you take home is using flea repellents on your body and clothes, taking your clothes to a washer or dryer, and flea treatment your cats and dogs. 

  • Fleas will hitchhike humans to move between rooms or spaces; they’ll also bite humans but prefer living and feeding on pets – they live primarily on the pet’s sleeping areas. 
  • Wear good flea repellents, clean the house and other spaces, inspect the pets for fleas, and consult a veterinarian (for pets) or doctor (for humans) if irritation or tapeworms are seen.
