Can Salt Help Control Flea Infestations?


Salt is one of many natural DIY treatments for controlling fleas. Find out how you can use salt to get rid of flea infestations at home.

Salt for Flea Control

For best results, you will want to use salt that is refined and of powdery consistency. As an alternative, we would highly recommend using food-grade diatomaceous earth.

Sprinkle Salt on Carpet
Salt could be a cheap DIY method for getting rid of fleas on carpets. Sprinkle a light layer of salt over your carpet then leave it there for close to 24 hours.

Vacuum the carpet thoroughly once a day has passed. Salt acts as a drying agent and can help remove the moisture needed by fleas to survive. You can also sprinkle the salt on pet beddings if you own a dog or cat.

Using Salt on Pets
Some articles may suggest rubbing salt on flea-infested pets. We would advise against this as the salt may cause major skin irritations, especially if your pet has open flea wounds.

Instead of salt, you could try rubbing other natural alternatives, such as coconut oil and aloe vera, on your pet’s body. These natural gels may also provide your dogs and cats some relief over the skin irritations caused by flea bites.

Salt for Backyard Flea Infestations
Some articles may suggest spraying the backyard with salt solution to get rid of fleas. Don’t do this as the salt can easily kill the plants in your backyard. Homeowners who have flea infestations in their yard should look at solutions like applying beneficial nematodes.
