Fleas need a meal consisting of blood to survive. Without a blood meal, fleas may only live for a few more days. Some adult fleas can live up to 2 weeks. A dormant flea can live even longer over a winter season without being disturbed. The maximum amount of days could be up to 100.

If there are no pets in your home, fleas lack a host and have no food options or blood meals. If a flea cannot host on you or a pet, it will try to remain still until a warm body passes by.

Without a pet or host, an adult flea can live only a few days or up to 2 weeks. In some cases, flea larvae can live on carpets by consuming debris found in the environment.

Some fleas are able to remain dormant for over 100 days without feeding. This can happen during the winter months where are fleas more commonly dormant and motionless.

Vacuuming is an excellent way to kill fleas in every stage of their lives. The success rate of using a vacuum on adult fleas is about 96% depending. The claim is that they are 100% capable of killing younger fleas and flea larvae.

The study in mention, doesn’t include flea eggs. The eggs are too fragile to survive vacuuming however. The hardiest and healthiest fleas are the adults who will be killed 96% of the time by vacuuming alone.

What Kills Fleas Instantly In Carpets?

You may have some supplies already in your home to kill fleas in carpets. The following items will help you effectively kill fleas who might be hanging out in your carpet:

  • baking soda
  • salt
  • lemon and water spray

How Can you Tell If Fleas are in Your Carpet?

A great way to tell if there are fleas in your carpet is by trying the white sock method:

The White Sock Method

  1. Put on a pair of socks that are white.
  2. Begin slowly dragging your feet over the rug or carpet with your white socks.
  3. After about thirty seconds, you can stop dragging your feet on the carpet.
  4. Use a flashlight to take a closer look at your socks.
  5. If you can see fleas on your socks, you now know that you have fleas in your carpet.

Inspect your carpet every few days to make sure that the fleas you have removed by using a flea killer or baking soda in a vacuum are gone for good.

How Often Should I Vacuum If I Have Fleas?

You should vacuum your carpet every other day to control the house that used to have fleas in it. Vacuuming is effective even when the fleas are in their egg stage because they are fragile and easy to suck into the vacuum cleaner.

If the eggs have been laid, they will hatch into larvae within two to three days. This is why it’s a good idea to vacuum before any new eggs are hatched. You are preventing a new generation of fleas from developing.

How Long Do Fleas Survive On Carpet?

Fleas can survive on carpets for an indefinite amount of time. As long as there is a host or blood meals available for the flea in this area, new eggs will hatch larvae and pupae will be found on the carpet and this generation of fleas will pass on to another.

Without a host in the house for the fleas to consume their blood, they will begin dying off within a few days. Some fleas can remain in the dormant stage and survive for up to two to three months.

This is why it is important to continuously inspect your carpet. Carpets can be vacuumed every two to three days to ensure that new eggs do not hatch into flea larvae.

Why Do Fleas Infest Carpets?

A carpet is a perfect location for a flea to lay up to 50 eggs per day. They can do this on the fur of their animal hosts as well. While pets are moving around inside the house the eggs can fall to the floor and find a cozy hiding place within the fibers of your carpet.

The larvae can embed itself deep into the carpet without you noticing them. They can also hide deep in pet beddings. These larvae can live inside the carpet and feed on detritus or debris for an indefinite amount of time.

There could be dried blood or feces of adult fleas that the larvae could also feed on. This is why fleas can remain dormant or undetected in carpets for up to two to three months.

Carpets that are made with higher piles of fiber are perfect hiding places for fleas to lay eggs and create future generations.

Are There Home Flea Remedies For Carpets?

Yes. You can use lemon spray with water and boil it the night before. Then transfer the contents into a spray bottle and begin spraying all over your carpets to kill fleas.

Keep in mind that vacuuming is your best final solution and always great to accompany any of the other methods that you may find to kill fleas. Without a host, a clean carpet that doesn’t contain any debris for flea larvae to dine on, all remaining fleas will die off within a few days.

How To Identify Fleas in Carpet

Fleas are incredibly small to notice with the naked eye. This is why you can try to get down to their level and search for fleas really closely and you can also use a magnifying glass. Run your fingers through the fibers of the carpets and hold a flashlight to get a better view as well.

A better way to use the “white sock method”. Drag your feet all over the carpet while wearing bright white socks.

The higher the socks the better they are because you may catch jumping fleas who are trying to attach to your leg. Now it’s time to inspect your socks and see if there are any fleas on there that are dead or alive.

How Can You Tell If there are Fleas on Your Carpet?

If you have a pet who is scratching his or herself constantly while on your carpet, there’s a good chance that there are fleas present. This is an easy indicator that you may have an infestation of fleas.

Check the head, neck and hind quarters of your animal. If you drag a towel across the carpet and find red streaks all over that means you have just dragged and killed a bunch of fleas.

Fleas like to lay eggs in rugs because this is a perfect hiding place. They are hard to spot especially in dark carpeting. Use a magnifying glass to help find these fleas. You can also use a fine-toothed flea comb and drag it across your carpet as well.

In order to prevent any chance of these fleas jumping, you can sprinkle the carpet with baking soda first and then begin testing to find out if you have any fleas.

Either way, you will have to vacuum up the baking soda and hopefully a few or all flea carcasses as well.

Will Removing Carpet Get Rid of Fleas?

You may not need to remove your entire carpet to get rid of fleas. Start with using a commercial flea killer or baking soda and sprinkle it or spray it all over the rug. Then you can vacuum or steam clean the carpet shortly after.

Removing the entire carpet might have to occur if you have repeated cases of flea infestations. If you’re pet regularly gets fleas, this is a good time to remove the carpet.

You might need to replace the surface of the floor with another type of flooring material instead of carpet which makes laying eggs much easier for fleas.

As an owner of a dog myself, I do not recommend using carpets in the home. They allow for a lot of debris that is dragged in from outside to remain in your home. Flea larvae do not need to consume blood. They can live off of the debris in carpets.

Carpets also invites plenty of dog hair. Did you know that cockroaches love to eat hair? This is a good idea if you would like to have more pests in your home or maybe you should reconsider using carpets all together.


Flea eggs stick well in carpets. It is a better place for the eggs to hatch than on the fur of your pet who is always on the move. If you allow your pets to sleep on sofas, beds and carpets you may have little flea eggs finding a place to hatch and turn into flea larvae.

A carpet usually contains enough debris for these larvae to survive for an indefinite period of time. Some fleas may die off without a host in a matter of days while others can survive up to 3 months.

If you do not take any steps to get rid of them, you will encourage future generations of fleas to continue reproducing.
