Why Does Citrus Deter Fleas?

The truth is that we don’t know the answer to this question. Some people believe fleas hate the smell of citrus, so they do their best to avoid it. Other people believe it’s the highly acidic nature of citrus.

Apple cider vinegar is another all-natural flea treatment remedy, and it’s also highly acidic. Regardless of how it works, the general consensus is that citrus sprays are a safe and effective way to treat and prevent fleas on dogs, cats and other household pets.

Create Your Citrus Spray

Take about half a dozen or so oranges and peel them, removing the fruit from inside. You can either eat or save the fruit for later, as you only need to the skins to create the citrus spray. The skins of an orange is where most of the essential oils and compounds are located.

Next, chop the skins into small pieces and place them in a pot of boiling water. Reduce to a simmer and let them slow cook for several hours, adding more water when needed. Strain the mixture so you have a pure liquid citrus solution with no skins or solid matter. Transfer the solution into a spray bottle and place it in the refrigerator to cool before using it on your dot.

Apply The Citrus Spray

Apply the citrus spray directly to your dog’s fur at least once a day. Since it’s highly acidic, citrus spray can burn their eyes, so use caution to avoid getting it around their face. I recommend shielding your dog’s face with your hand while you spray their body.
