Will Fleas Go Away Without Pets? Explained

Fleas are parasites that feed off the blood of warm-blooded hosts such as cats, dogs, humans, and other animals. Fleas can spread numerous diseases and cause severe discomfort to their hosts, but they can also cause an infestation in homes even if no pets live there. So, the question is – will fleas go away without pets? The answer is yes or no, depending on the specific home or location conditions.

Fleas will not typically remain in an environment if no animals are present to serve as hosts and provide food sources. Without an animal host, flea eggs cannot develop into adult fleas; additionally, adult fleas have a relatively short life span of only two to three months without host animals. However, fleas can enter a home from outside sources like wildlife or workers going in and out of buildings carrying flea eggs on their clothing or tools.

If you do not have pets in your home but want to get rid of flea infestations, chemicals may be necessary to eliminate the insects from your environment. A professional exterminator may help create an effective plan that meets your particular needs and situation. Additionally, thorough cleaning practices such as frequently vacuuming carpets and furniture may help reduce adult fleas living inside the house.

What Are Fleas?

what are fleas

Fleas are tiny, parasitic bugs that feed on the blood of people and animals. They can be challenging to get rid of, especially in homes with pets. Fleas are usually found in carpets, rugs, furniture, and pet bedding.

Understanding what fleas are and how they can affect your home is important before deciding on a flea control method. In this article, we’ll discuss fleas and how to deal with them:

How Do Fleas Spread?

Fleas can be tough to eliminate from any environment, as they are highly adaptive and can become resistant to chemical treatments. Understanding how fleas spread is the key to effectively controlling them.

Flea eggs and larvae live in organic matter such as dirt, bedding, carpets, and upholstery. Flea larvae feed on the skin flakes found in this matter. Adult fleas use a host, usually pets, for a site for renewal and reproduction. With each jump (fleas can jump 8 inches high!), the fleas transfer from pet to pet until eventually making their way into carpeting, bedding, and other fabrics in your home or outside environment. As a result of this process, most treatments should address all affected surfaces within your home or yard to eliminate fleas effectively.

In addition to jumping from host to host or environment to environment (e.g., hitchhiking in clothing or luggage), it’s worth noting that some species of fleas can sometimes go without a host source for nutrition for several months at a time before needing another meal of blood. To prevent the establishment of adult fleas inside the home, it is often suggested to treat both indoors AND outdoors and not just indoors alone.

Can Fleas Survive Without Pets?

Fleas are small, tough insects that can live anywhere and quickly spread if they go unchecked. One of the most common questions about fleas is whether they will die off if there are no pets in the environment.

In this article, we will look at whether fleas can survive without pets and what you can do to prevent them from invading your home:

Factors That Determine Flea Survival

Fleas cannot survive without a host, but the amount of time they can survive on their own depends on many factors, including temperature and humidity. Therefore, the answer to the question, “Can fleas survive without pets?” is not entirely straightforward.

When a flea infestation occurs in a home where no animals are present, it’s essential first to determine if other factors could influence their survival – such as environmental conditions. For example, fleas need certain temperatures and humidity levels to thrive, such as temperatures from 65 to 80 degrees Fahrenheit and relative humidity between 75% and 90%.

Without these temperatures and levels of moisture present in their environment, the fleas may not be able to reproduce or feed effectively. However, if conditions become unfavorable for flea survival, adult fleas may enter a state of dormancy known as “diapause” until conditions become favorable again.

Although fleas will naturally find ways to keep themselves alive under challenging circumstances – such as when they attach themselves to humans – they are much more likely to stay alive if they can feed off warm-blooded animals like cats or dogs. Even though some fleas can bite humans, it’s much harder for them to survive off human blood alone. Flea pupae may also remain viable for long periods while waiting out unfavorable environmental conditions before emerging into adulthood.

How to Get Rid of Fleas Without Pets

Fleas often hitch a ride on humans, making it easy to carry them home, even without pets. Unfortunately, many pet owners who have fleas often have to deal with the headache of getting rid of them. But what if you don’t have any pets in your home? Can you still get rid of these pests?

Fortunately, some solutions can help you eliminate fleas without having pets in your home. Let’s take a look at some of these solutions:


Vacuuming can help eliminate fleas without pets as it can quickly and effectively suck up adult fleas, eggs, and larvae. Vacuuming carpets, furniture, unseen cracks, and crevices around floor edges and in areas where pets frequent will help to remove a large portion of the flea population. Vacuum bags should be promptly discarded along with any found fleas, as they may escape from the bag during disposal.

In addition, carpets should be steam-cleaned for deeper penetration and removal of more difficult-to-remove larvae and eggs. For best results when vacuuming, start at one end of the room, slowly overlapping strokes across the entire floor surface.

Using Flea Bombs

Flea bombs or “total release foggers” are chemical insecticide products designed to control fleas in your home. Flea bombs contain pyrethrin or synthetic pyrethroids, chemicals designed to suffocate and kill insects. A single fogger is usually used for a single room, and multiple foggers should be used for larger areas such as houses.

The flea bomb should be set off in an unoccupied space and closed off, as its smoke will fill up the area rapidly. Allow the bomb to work undisturbed, and open all windows and doors to air out the site. Keep pets (and people) away from the treated area until all residue has settled and been removed with a vacuum cleaner.

If the infestation is significant, it may take more than one repetition of this process to eliminate fleas in your house completely. Still, it can be more efficient than other chemical treatments like sprays because it covers more evenly in a single application.

Applying Insecticides

Applying insecticides is a good option for getting rid of fleas without pets. For example, you can use baits or insect growth regulators such as methoprene to eliminate the flea population in your home.

  • Baits are tiny granules that contain an insecticide and are meant to be scattered around your home and in areas of high flea activity. These baits will attract fleas, kill them and stop the larvae from maturing.
  • Insect growth regulators such as methoprene prevent the larvae from maturing and becoming adult fleas, which will ultimately help break the life cycle of the infestation.

Insecticidal dust, sprays, and foggers can also be used to eradicate a flea problem if applied correctly. It is essential to read labels carefully; some products are toxic if misused or on certain surfaces. Therefore, seeking professional assistance when using these products may be a good idea to ensure you don’t harm yourself or others.


In conclusion, yes, fleas can and will go away without pets in the home. Flea infestations are usually caused by a combination of factors, including high humidity, warm temperatures, and the availability of food sources.

Therefore, as long as these moisture and temperature conditions are maintained at reasonable levels within the home and no food source (such as pet fur), fleas will eventually die off from lack of sustenance.

However, even if you remove all pets from your home or take steps to reduce environmental factors that could be contributing to a flea infestation, an individual or two can breach the home’s defenses due to jumping through open windows or doors or by being carried in on furniture or other objects from outside.

Therefore it is essential also to take appropriate measures such as:

  • Vacuuming regularly
  • Washing bedding at high temperature washes once a week for at least two months.
  • Checking for visible signs of fleas on pets brought into the home before allowing them inside

With these activities performed faithfully, your chances of eliminating a flea infestation increase significantly.
