Does Lysol Kill Fleas? or is it Not as Effective?

Itchy bites are no fun! Fleas are annoying pests who drink the blood of people or pets. They can spread, move,  and reproduce quickly, so it is important to be aggressive when dealing with fleas in your home!

What Is Lysol?

Lysol is a general disinfectant and cleaner that many people use in their homes. It is advertised to kill 99.9% of viruses and bacteria. It is inexpensive and comes in many different forms, such as liquid, wipes, or a spray.

Lysol is easy to find, too, and can be purchased at just about any grocery store, drug store, or convenience store!

Is Lysol a Good Solution to Kill Fleas?

If Lysol is sprayed directly on a flea, it will kill it. Remember, fleas are fast! It may be difficult to hit every single flea with Lysol. Also, Lysol does not kill flea eggs, so you will have to find a different solution to deal with the eggs.

Does Lysol Repel Fleas?

Fleas do not enjoy the scent of Lysol, so they will typically avoid an area that has a high concentration of Lysol present. Thoroughly cleaning your home with Lysol is a good way to keep fleas away!

How Do I Use Lysol for Fleas?

  • Find areas with flea activity. Look at the carpet, bedding, and furniture.
  • Clean your home thoroughly. Remove all garbage, clutter, and food debris.
  • Apply Lysol in spray form throughout your home. You will want to apply it in higher concentrations in the areas where you’ve spotted fleas.
  • Use another method to remove the flea eggs.
  • Repeat regularly until all signs of fleas are gone.

Fleas, Lysol, and Pets

Chances are, if you have fleas in your home, they were brought there by a pet. Pets are notorious for carrying and sharing fleas. You must treat your pets for fleas, too.

Do not use Lysol on your pet! Lysol is toxic to pets if ingested. The phenol in Lysol is not only toxic to dogs and cats if it is ingested, but it can also cause chemical burns in their throats and on their skin.

Make sure your pet is safely out of the room if you are treating your home with Lysol.

Use a flea shampoo, like this one to thoroughly wash your pet. Follow all instructions on the bottle. You may need to reapply the treatment.  Once all the fleas are off your pet, you will want to use a flea preventative like this one for dogs, or this one for cats.

Safety Precautions

Though Lysol is a common household staple, it still is a chemical and should be treated with caution. Avoid contact with your eyes. If contact occurs, flush eyes with cool water immediately.

Avoid inhaling Lysol. If accidental ingestion occurs, call poison control, or another medical professional.

What Are the Other Ways to Kill Fleas?

I recommend a combination of flea removal methods to ensure that your home and pets are completely free of fleas and flea eggs.

Removing Flea Eggs

If you remove all the adult fleas but don’t do anything about the eggs, you will continue to have a flea problem! Steam will kill flea eggs. Use a heavy-duty steam cleaner that can reach a high temperature.

Steam all carpet and furniture thoroughly. Repeat as needed until all signs of fleas are gone. Wash bedding, curtains, rugs, and clothing in hot water. The heat should kill all the flea eggs.

Diatomaceous Earth

Diatomaceous Earth is a non-toxic way to kill fleas in your home. It is made of ground-up diatoms. It feels like a soft powder to our touch, but it is full of microscopic, jagged edges that destroy fleas and other insects.

Sprinkle it wherever you have seen flea activity. Vacuum up the earth and the flea carcasses after one to two days. Repeat as needed.


A thorough vacuuming is a good way to remove fleas, flea eggs, pupae, and excrement. If you have fleas in your home, I recommend vacuuming carpet, rugs, and furniture daily. This should remove 30-90 percent of adult fleas and flea eggs, depending on your vacuum.

Professional Help

If you have an overwhelming number of fleas in your home, contact a professional exterminator. You may want to consult your veterinarian as well to make sure your pets are properly treated for fleas.

Final Thoughts

Fleas are a pesky problem! I recommend a combination of methods to ensure that they are gone for good! Don’t forget to treat your pets for fleas, as well.
