11 Foolproof Methods to Keep Fleas Away from Your Home (2024)

Flea infestations are common in a home with cats and dogs and using a natural flea repellent can help the problem.

There are hundreds of flea repellents on the market that use chemicals but using natural methods to control fleas can be safer especially if you have small children. Products you have on hand like salt, baking soda, dishwashing liquid, and essential oils can repel fleas.

Here is how to get rid of fleas with 11 natural repellents.

Start With Deep Cleaning

It can't be said enough for flea control, deep cleaning is a must. Flea eggs can lie dormant and hidden until movement triggers eggs to hatch, so leave no nook or cranny untouched.

  • Vacuum thoroughly:Don't just focus on pet beds or resting areas. Flea eggs are often trapped between the baseboard and the floorboard. Flea eggs are especially prone to piling up inside the cracks of sofas. If your pet is allowed on the furniture, vacuum the upholstery and all the cracks and crevices of your couch or chair. Always empty the vacuum dirt reservoir or dispose of the vacuum bag in an outside trash can.
  • Use a steam cleaner: The heat of steam will kill fleas and their eggs. Steam clean carpets, area rugs, upholstered furniture, and mattresses.
  • Clean pet beds:Pet bedding should be washed in hot water or replaced once the flea infestation is eliminated. If you're working hard to get rid of fleas inside, check your dog's outside doghouse and clean it well.


Pets often bring fleas in from outside. If your yard isn't well maintained, rodents (mice, rats, squirrels) may be carrying fleas that could spread to your dog or cat.

11 Natural Flea Remedies

Diatomaceous Earth

Diatomaceous earth is a naturally occurring powder made from the microscopic remains of diatom algae that penetrates the exoskeleton of a flea and kills it through dehydration. It can kill fleas within four hours. While non-toxic to pets and humans except when inhaled, sprinkle it around infested areas indoors and outdoors.


Sprinkling salt where fleas are active will also dehydrate the eggs and insects. Salt works well on carpets and upholstery where it can be easily vacuumed away.

Baking Soda

Another desiccant, baking soda will cause fleas and their eggs to become dehydrated and die. Sprinkle it liberally and let it work for at least 24 hours before vacuuming. Be sure to dispose of the dust cup contents or bag in an outside trash can in case some fleas are still alive.

Dish Soap

Dishwashing liquid and water and trap live fleas. Fill a bowl with warm water and 1/4 cup of dish soap and place it near an area where you have a flea infestation. This should be done at night when the fleas are most active. The fleas will become trapped in the soapy solution. This does not, however, take care of the eggs that are still waiting to hatch.

Rosemary Oil

Fleas and ticks do not like the scent of rosemary. Plant it outside to help repel fleas from your yard. The rosemary oil can be combined with baking soda to make a flea powder to sprinkle on carpets, furniture, pet bedding, window frames, and anywhere else you suspect flea activity in your home.

Lavender Oil

Lavender is another natural flea repellent. Add a few drops of lavender oil to baking soda or cornstarch to create an herbal flea powder repellent.

Peppermint Oil

The refreshing smell of mint attracts humans, but it is overpowering for fleas. Any mint oil can be used to create a herbal flea powder. Mint planted near entrances of your home will also help keep fleas away.

Cedarwood Oil

Add two to three drops of cedarwood oil to two cups of water in a spray bottle to repel fleas in the home. You can also place cedar chips in bowls near flea infestations to repel the pests.

Citrus Spray

Add 1/4 cup of fresh lemon juice to 2 cups of water in a spray bottle. Spray flea-infested animal bedding areas. They should not be used to spray entire rooms, nor should they be used outdoors. EPA-registered citrus shampoos are mild enough for use on young animals, but veterinarians caution that some cats may suffer if the material is applied in excessive concentrations.

Boric Acid

Boric acid powder acts as a desiccant to kill fleas and roaches. Use a very fine dusting on surfaces and in cracks where fleas will crawl over the powder and ingest it. Use in cracks and crevices, edges of cabinets, and on the floors behind appliances. Do not use boric acid on kitchen counters since it is slightly toxic to humans.

Bath Oil

Studies show a 31-62% reduction in fleas when animals are bathed with 1.5 ounces of Skin-So-Soft bath oil with 1 gallon of water. The key is washing with the solution frequently so that the fleas can't repopulate on your pet. This treatment will only work well if deep cleaning of bedding and resting spots is also done.

When to Call a Professional

If the infestation is severe, a pest professional can help. While targeted chemical treatment can be necessary to get rid of severe flea problems, it's a band-aid solution if the source of the fleas isn't addressed.
