How to Get Rid of Fleas on Your Dog Naturally

Natural Flea Powders and Sprays

To naturally repel fleas, dust your dog with a herbal flea powder made from ingredients like rosemary, wormwood, pennyroyal, citronella, rue, tobacco powder, and eucalyptus. These natural herbs help deter fleas without harming your pet. You can also make your own by mixing equal parts of eucalyptus, rosemary, fennel, yellow dock, wormwood, and rue in a shaker jar. Apply sparingly to the coat, focusing on the neck, back, and belly, and brush backward to work it into the base of the hair.

For added protection, use a spray made by mixing a few drops of herbal flea oil (like pennyroyal, eucalyptus, or citronella) with water. Spray both your dog and the home to discourage fleas from returning. After treatment, let your dog go outside so fleas may leave the house rather than stay indoors.

Diatomaceous Earth and Home Cleaning

Apply food-grade diatomaceous earth to carpets, furniture, and your dog’s bedding. This powder, made from fossilized algae, dehydrates fleas and kills them quickly. It’s safe for humans and pets when used correctly but should be avoided in areas where your dog eats or sleeps for long periods.

Thorough cleaning is essential. Vacuum floors, carpets, and furniture weekly, especially in areas your dog frequents. Wash your dog’s bedding once a week in hot water and dry on high heat. Steam-clean rugs and carpets at the start of flea season. These steps remove flea eggs, larvae, and pupae from the environment.

Herbal Collars and Internal Repellents

Herbal flea collars are a safe, non-toxic option. Some are made from flexible plastic or rope-mesh that can be recharged with herbal oils. Common ingredients include pennyroyal, eucalyptus, and citronella. You can also use a product like Earth Animal’s Herbal Internal Powder, which contains garlic, alfalfa, wormwood, and yellowdock. Sprinkle it into your dog’s food daily—it repels fleas and is safe for long-term use.

Another option is Internal Powder (Earth Animal), which contains garlic and brewer’s yeast. These ingredients make your dog’s body less appealing to fleas. The smell may be strong, but it’s effective and natural.

Diet and Environmental Control

Feed your dog a natural diet free of additives and preservatives. Adding fresh garlic and brewer’s yeast to their morning meal can help repel fleas from the inside out. Garlic and brewer’s yeast are known for their flea-repelling properties.

In the yard, mow the lawn regularly to expose flea larvae to sunlight, which kills them. Watering the lawn can drown developing fleas. Encourage ants by avoiding pesticides—they eat flea eggs and larvae. Cover bare-earth spots with black plastic on sunny days to trap heat and kill fleas. Apply agricultural lime to moist or grassy areas to dry out the environment.

Bathing and Preventive Care

Bathe your dog with a capful of pennyroyal or eucalyptus oil in warm water. This helps kill fleas on contact. After bathing, flush the soapy water and fleas down the toilet. Use a flea comb to remove any remaining fleas and flea dirt, wiping the comb clean as you go.

Brush your dog frequently to strengthen their immune system and reduce parasite load. Regular exercise and occasional fasting may also help boost resistance to disease and parasites.
