If you’ve been looking for natural ways to repel and kill fleas on your dog, you might already know that lemon is a crucial ingredient. The citrus fruit contains a compound called limonene, which has insecticidal properties and can keep fleas away from your furry friend. One of the most popular ways to use lemon against fleas is a lemon spray. We’ve shared two simple recipes to make a lemon flea spray for your dog.

Basic lemon flea spray
For this recipe, all you need is water and lemons. Boil a pint of water in a pot and add around ten slices of lemon to it.

Cover the pot with a lid and let the mixture sit overnight for about 8 hours, and the solution will be ready! Remove the lemon slices and pour the solution into a spray bottle. You can spray this solution on your dog’s coat generously every day until they are flea-free. While spraying, avoid areas like your pet’s ears, genitals, and eyes. An excellent plus point of this lemon flea spray is that you can use it in all flea-infested areas in your home, such as your dog’s bed, your carpet, and your upholstery.

Lemon flea spray with rosemary and sage
This recipe is similar to the previous one, except you need to add two sprigs of rosemary and one sprig of garden sage while boiling the water.

These plants contain compounds that can help repel fleas even more strongly when combined with lemon. Let the lemon slices, rosemary, and garden sage steep in water overnight. Once the solution is ready, strain it into a spray bottle and apply it to your dog’s coat while avoiding the sensitive areas. Some pet owners also make flea collars using lemon and rosemary solutions for their pets. The recipe is the same as above, except you need not use garden sage. After the solution is ready, add a few drops of it to your dog’s regular flea collar. That’s it! It’s best to introduce this flea collar to your pet slowly. This way, they’ll become familiar with the new scent and won’t mind wearing it all day long.
