Rather than poisoning fleas and ticks, they repel them. The repelling effect safely prevents a dog from becoming host to fleas.

What are the Benefits of Using Natural Flea Repellent for Dogs?

There are many benefits to using natural remedies for dogs. Here are some of the benefits of using a natural flea killer for dogs:

  • No Harsh Chemicals. The regular flea treatment for dogs (topicals, oral tablets, and flea collars) contains insecticides and chemicals that can kill adult fleas and larvae. Common ingredients are permethrin, pyrethrin, and fipronil. Natural flea killers and repellents are free from such chemicals.
  • Suitable for Sensitive Skin. Mainstream, chemical flea prevention products may cause irritations and allergic reactions in sensitive dogs. Natural flea repellents are safe even for dogs with skin sensitivities.
  • Easy to Use. Most natural flea repellents for dogs are easy to use. All they take is simple scrubbing of the dog’s coat with hands, saturating the fur with a mix in a spray bottle, or pouring a shampoo mixture over a dog’s coat will work.
  • Budget-Friendly Protection. Many natural flea repellents are inexpensive and can be made with ingredients the pet owners already have in their homes, such as lemon juice or coconut oil. Others can be purchased online for budget-friendly prices.

There are many products and methods available in stores and online that work to repel fleas naturally. Listed below are a few examples that may work for your dog.

Bragg Organic Apple Cider Vinegar. The Bragg Organic Apple Cider Vinegar is made with natural ingredients and offers various health benefits, including solving the flea problem in dogs.

After you wash a dog with its normal soap, mix one-part apple cider vinegar (ACV) with five parts of warm water and pour it over the dog. Rub the apple cider vinegar into the dog’s skin and let it sit for a minute or two. Rinse with warm water afterward.

Wholistic Pet Diatomaceous Earth. The Wholistic Pet diatomaceous earth product consists of organic ingredients. In addition to repelling fleas naturally, diatomaceous earth supports the dog’s overall health.

Diatomaceous earth kills and prevents fleas and flea eggs from dogs and the environment. It works by damaging the exoskeleton and draining the water from the fleas’ bodies. However, only diatomaceous earth labeled as “food-grade“ is safe for dogs.

Essential Oils. Essential oils can be great for treating and killing fleas on dogs. However, in their raw form, oils can be dangerous to dogs. Vitality Extracts states that only diluted oils are safe for dogs.

You can use one drop of essential oil (eucalyptus, palmarosa, lavender, lemon, clary sage) per one milliliter of carrier oil (like coconut oil). Do not use wintergreen, pennyroyal, clove, or peppermint essential oils, as they can be dangerous to dogs.

Lemon Juice. Lemon is a natural flea-repellant and can be used in the form of a lemon spray as a daily preventative. Simply mix water and a few drops of lemon juice into a spray bottle.

Instead of spraying, you can practice lemon juice baths. Just add a few drops of lemon juice to the dog’s shampoo. This is a great recipe for making a DIY flea shampoo.

A lemon juice bath can also be an effective way to prevent and treat fleas. A few drops can be added to any dog-safe shampoo. You can also make a DIY flea shampoo by adding equal parts of lemon juice and baking soda to the shampoo.

Zesty Paws Coconut Oil. The Zesty Paws coconut oil can be used internally or externally on the dog’s fur. When used on the dog’s skin, it helps relieve itchiness and irritation caused by flea bites.

Coconut oil, in general, doesn’t kill fleas. However, it is the most commonly used carrier oil in natural flea repellents for dogs. Plus, with the flea bite managing component, coconut oil is a 2-in-1 product for dogs.

Tropiclean Natural Flea and Tick Spray for Dogs. This natural flea spray for dogs kills fleas, larvae, eggs, and ticks on dogs 12 weeks or older.

However, be careful not to spray it on the dog’s eyes, mouth, and nose.

The natural flea killer for dogs can be used on its own or in conjunction with flea combs. Flea combs are excellent for removing fleas physically.
