It happens now and again when the circumstances are exactly right. Fleas find their way into your home. It’s never just one, and the problem only goes away on its own if you’re lucky. It’s aggravating, but you need to know a little bit about these blood parasites (insects) and how to deal with them to eradicate them from your house properly.

This article will look at how you get fleas in your home when you don’t have a pet.

Can You Have Fleas Without Pets? 

How do you get fleas in your home when you don't have a pet?

Yes, you could have fleas without having pets. If you’re worried that fleas have infested your home, although you don’t have any pets, keep an eye out for the following signs:

Flea Facts


Flea eggs hatch in 1 to 6 days, depending on the temperature and humidity of the environment. Depending on the weather, full growth from egg to adult might take many weeks or months.

Without a host, a flea may live for 3 to 4 months. They may be calmly waiting for you to walk by if they were left off in your yard by a stray or wild animal. Adult fleas stay in places for their lifetime.

Bites are not only inconvenient for humans and animals, but they also pose a major health danger. Fleas can transmit plague and murine typhus.

They also act as intermediate hosts for dog and rodent tapeworms, infecting people, particularly small children, on rare occasions. When fleas are mistakenly swallowed, an infection might result. 

How do you get fleas in your home when you don’t have a pet?

Just because you don’t have pets doesn’t mean fleas aren’t an issue in your house. Fleas can get into your home in a variety of ways. Examine how fleas could have gotten into your house.

Neighbor’s Pet

Flea infestations are notorious for going undiscovered until the population has grown out of control. With that in mind, fleas were probably introduced to your property by a neighbor walking their dog.

When a neighbor’s dog goes for a walk, the dog sniffs around in your yard, scratches, and leaves fleas, flea eggs, and pupae behind. Then you go for a walk around the yard, track them in, and stimulate the fleas the next time you vacuum and have a flea issue.

Window Crack Areas

Fleas are small. They do not require hosts to enter our houses. They may get inside a house through floor gaps, window screens, and even under the door. The easiest approach to avoiding a flea infestation is to vacuum and clean your home, as well as wash your pet and its bedding regularly.

Infested Animals (Cat fleas)

Fleas may infest animals such as squirrels and raccoons. The fleas, eggs, or pupae that rode in with them may have leaped or been rubbed off if the animal scratches or rubs its hair in the grass, on walls, or even picks its way through your landscaping. It’s probable that if they’re in your yard, they’ve brought fleas with them.

Fleas come uninvited to your home from stray animals. Stray animals, such as dogs and cats, spread flea infestations on porches, decks, and around home doors. 

Carried in with You


Fleas lurk among grass and foliage until they locate a host. They’re great jumpers and can quickly latch on to you when you’re out in the yard. If that’s the case, you may have carried fleas, if not ticks, home with you.

Fleas are opportunists who wait in locations with long grass and weeds for the perfect opportunity to leap onto a prospective passing host. It’s possible that you were the host.

Rodents in Yard


Aside from their capacity to spread, a major issue with fleas, particularly for individuals who do not have pets, is that a flea infestation might indicate worse problems.

Fleas may use rodents as a home and a mode of transportation, and after the rodents have settled in, the fleas will spread out in search of new food.

If you have fleas but no pets, it’s a good idea to check for a possible rodent infestation as well. Rats have their own set of issues, and having rodents and fleas together may be dangerous, as fleas can carry rodent tapeworm, which is transmitted to people.

Left Behind

If you’ve recently moved into a new house and discovered fleas, there’s a good possibility they were already there. Flea eggs might have been left behind even if the previous owners had dealt with the problem.

It’s possible that the former owner or tenant had pets, and the pets had fleas. They left the fleas in the carpets as they moved out.

Fleas remain in their cocoons until they detect vibration in this condition. They have months to wait! Those mature fleas are now on the hunt for food. People become the best option when a dog or cat is not accessible.

Secondhand Items

Have you found a great price on a couch or other useful item? They likely got such a good price because there were a lot of fleas, pupae, or eggs hidden in the item’s nooks and crannies.

It is why it’s best to either buy new, check extensively before purchasing, or completely clean an item before bringing it into your house.

It will prevent you from bringing fleas or, worse, bed bugs into the house. Fleas may go for months without eating, so if you’ve recently moved into an apartment or house and are noticing fleas, it could be an unintentional housewarming present from the previous tenants.

How to Prevent Fleas From Entering Your Home?

To avoid fleas, take the following steps in your house and yard. We’ve compiled a list of helpful hints to keep these pests at bay.

  • Clean Yard: Fleas hide in thick grass and shrubs, so keep your yard clean. Regularly mow your yard, trim shrubs and plants, and pull weeds. Keep the yard clear of debris such as logs, leaves, pebbles, and other materials that might give fleas a haven. Remove any garbage that might attract wildlife from your yard.
  • Seal Entry Points: Fleas will have a harder time getting into your house by sealing entry points. Seal any cracks and replace any broken or damaged door or window screens. Ensure that animals, such as flea-infested rats, cannot enter your garage, shed, attic, crawlspace, or beneath your deck.
  • Long Grass: Avoid Walking in Long Grass When Spending Time in Nature: Stay away from tall grass when spending time in nature. Fleas may readily jump on you from grass blades. To help keep these bugs from biting, wear slacks, long socks, and long-sleeved shirts whenever feasible.
  • Reduce Dampness: Fleas are drawn to wet yards because they adore moisture. To keep these pests at bay, don’t overwater your plants. Remove objects that gather water and eliminate sources of standing water.
  • Create a Protective Barrier: Spray your yard with a plant-based pesticide to help inhibit flea activity.


It’s disheartening to discover a flea infestation, but don’t lose hope. If you take the right steps, you may get rid of them rapidly. Every few days, vacuum. Regularly clean your lawns and dispose of any rubbish as soon as feasible.

An essential thing to remember is to treat your house, yard, and pet all at once. It may aid in the prevention of re-infestation.
