Fleas and ticks are more than just an annoyance. They can cause itching, skin irritation, allergic reactions, discomfort, and in some cases, serious disease. For many pet parents, especially those who prefer a more holistic approach, the question becomes: How can I protect my dog while reducing unnecessary chemical exposure?

We recently attended a PetSummit webinar that shared professional recommendations for natural flea and tick options for pet parents. Since flea and tick prevention is one of the most common topics we receive questions about, we wanted to pass along this helpful guidance.

Dr. Megan Barrett, an integrative veterinarian in Hawaii, discussed natural flea and tick prevention methods for dogs, including environmental management, grooming, carefully selected natural repellents, and the importance of working with your veterinarian.

Why Flea and Tick Prevention Matters

Fleas and ticks may be small, but they can create big problems for dogs.

Fleas are tiny insects that feed on blood. Their bites can cause itching, redness, skin irritation, allergic reactions, hair loss, hot spots, and secondary skin infections. Some fleas can also carry tapeworms, which dogs may ingest while chewing or grooming themselves.

Ticks are arachnids, meaning they are related to spiders. They can be harder to kill than fleas and may carry diseases such as Lyme disease, anaplasmosis, ehrlichiosis, and Rocky Mountain spotted fever.

Because of these risks, prevention matters. However, prevention does not always look the same for every dog. Your dog’s age, health status, lifestyle, local parasite risk, coat type, sensitivity level, and environment should all be considered when choosing a flea and tick prevention plan.

Flea Control Starts With the Environment

One of the most important points to understand is that the fleas you see on your dog may only be a small part of the problem. According to Dr. Megan Barrett, "The fleas that are found on your pet only represent about 5% of the total flea infestation you may be experiencing."

Adult fleas on your dog are often just one stage of a larger infestation. Flea eggs, larvae, and pupae may be hiding in carpets, rugs, furniture, bedding, cracks in flooring, and outdoor areas.

That means flea control should not focus only on your dog. Your home and yard matter, too.

Helpful environmental steps include:

• Washing dog bedding, blankets, and washable fabrics regularly.
• Vacuuming carpets, rugs, upholstery, baseboards, and areas where your dog spends time.
• Emptying vacuum contents promptly and safely.
• Keeping grass trimmed in areas where your dog plays or rests.
• Removing piles of leaves, yard debris, and damp shaded areas where pests may hide.
• Cleaning consistently for several weeks if you are dealing with an active flea problem.

During an infestation, one cleaning session is usually not enough. Because the flea life cycle can continue for weeks to months, consistent cleaning is key.

Wildlife Can Increase Flea and Tick Exposure

Fleas and ticks are often carried by wildlife. Deer, squirrels, field mice, feral cats, mongoose, wild pigs, and other animals can bring parasites into yards, fields, wooded areas, and neighborhoods.

This makes it nearly impossible to keep an outdoor environment completely free of fleas and ticks, especially in certain regions. However, you can still reduce risk by keeping your yard maintained and checking your dog regularly.

Conventional Products: Be Informed

Conventional flea and tick products include spot-on treatments, collars, oral medications, and other pesticide-based options. These products can be effective and are widely used, but they should not be viewed as risk-free for every dog.

Some dogs may experience adverse reactions, ranging from mild skin irritation or digestive upset to more serious neurological signs.

One class of flea and tick medications, called isoxazolines, includes products such as Bravecto, Credelio, NexGard, Simparica, and Revolution Plus. These medications are designed to affect the nervous system of fleas and ticks.

Pet parents should be aware that some labels may include warnings about possible neurological side effects, including tremors, seizures, and loss of coordination. Other possible side effects may include vomiting, diarrhea, itching, lethargy, or skin reactions.

This does not mean every dog will react poorly. Many dogs use these products without obvious issues. However, it does mean pet parents should be informed, read product labels when available, ask questions, and watch their dog closely after starting any new product.

Flea and tick collars may raise additional concerns for some families because they continuously release active ingredients. These residues may transfer to bedding, soil, grass, water, furniture, or surfaces in the home.

It is also important to remember that many products are not a true “force field.” Some kill fleas or ticks after they bite or attach, while others may repel to varying degrees. No product can guarantee complete protection from flea- or tick-borne disease.

Natural Prevention Requires Consistency

Natural flea and tick prevention is usually not a once-a-month solution. It often requires a more hands-on routine.

A natural plan may include:

• Regular grooming.
• Daily tick checks.
• Flea combing.
• Bathing with a gentle dog-safe shampoo.
• Washing bedding.
• Vacuuming frequently.
• Maintaining the yard.
• Using carefully selected natural repellents.
• Monitoring your dog’s skin and coat closely.

This approach may take more time, but many pet parents feel it is worthwhile if it helps reduce chemical exposure while still supporting parasite protection.

Grooming Is One of the Best Early Detection Tools

Regular grooming is simple, but powerful.

Brushing, bathing, and flea combing give you the chance to look closely at your dog’s skin and coat. This can help you catch fleas, ticks, irritation, wounds, bumps, or skin changes early.

Pay special attention to areas where fleas and ticks commonly hide, including:

• Behind the ears.
• Around the neck.
• Under the collar.
• Armpits.
• Groin.
• Underbelly.
• Base of the tail.
• Between the toes.

Dogs with thick or long coats, such as huskies, golden retrievers, and other double-coated breeds, may need extra attention because pests and skin irritation can be harder to see.

Finding even one flea should prompt action. Check other pets, wash bedding, vacuum thoroughly, groom more often, and strengthen your prevention routine before the problem grows.

Bathing May Help Support Flea and Tick Management

Bathing can be another useful part of natural flea and tick care.

A gentle, dog-safe shampoo may help keep the coat clean, remove debris, and give you another opportunity to inspect your dog’s body. Some dogs may tolerate once- or twice-weekly baths, while others need less frequent bathing depending on their skin and coat.

Watch your dog’s skin closely. If bathing causes dryness, redness, flaking, itching, or irritation, reduce the frequency and talk with your veterinarian about a better shampoo option.

Essential Oils: Use With Caution

Some essential oils, such as lavender, cedarwood, and peppermint, are commonly used in natural flea and tick sprays for dogs. However, essential oils must be used carefully.

Natural does not automatically mean safe.

Essential oils should be properly diluted, used in dog-safe formulations, and avoided around sensitive pets unless recommended by a knowledgeable professional. Tea tree oil, for example, is one oil known for its potential to cause adverse reactions in pets.

Dogs also have a much stronger sense of smell than humans. What smells mild to you may feel overwhelming to your dog.

If you choose to use essential oils:

• Choose high-quality products from reputable sources.
• Avoid applying oils near your dog’s face, eyes, nose, or mouth.
• Never use essential oils undiluted.
• Use them in a well-ventilated area.
• Start slowly.

Watch for signs of sensitivity, such as drooling, sneezing, coughing, lethargy, skin redness, vomiting, or unusual behavior.

A gentle way to start is by placing a properly diluted product on something removable, such as a bandana, instead of directly on your dog’s skin. This allows you to remove it quickly if your dog seems uncomfortable.

Cats require even more caution. Many essential oils that may be considered for dogs are not safe for cats. Do not use essential oils on or around cats unless you are working with a veterinarian or qualified expert who understands feline safety.

Let Your Dog Have a Say

One thoughtful approach is to allow your dog to smell an oil from a short distance before using it.

Do not force the bottle near your dog’s nose. Simply observe.

If your dog walks away, turns their head, sneezes, becomes restless, or seems uncomfortable, that scent may not be a good fit. If your dog seems calm, curious, or unbothered, it may be something to consider in a properly diluted blend.

Your dog’s comfort matters. Natural prevention should still be gentle, respectful, and centered around your dog’s well-being.

Dietary Supplements Sometimes Used for Flea Support

Some pet parents explore supplements as part of a natural flea prevention plan.

Garlic is one of the more controversial options. Some holistic veterinarians use very small amounts of garlic for dogs, but garlic can be unsafe in higher amounts or for certain dogs. It should not be used casually. If you are interested in garlic, speak with your veterinarian or an integrative veterinarian first.

Brewer’s yeast is another supplement sometimes used as part of a natural flea routine. It contains B vitamins and may support skin and coat health. However, it should not be relied on as the only form of prevention.

Apple cider vinegar is another option some pet parents use. It may be diluted and applied externally to the coat, often mixed one-to-one with water. Some pet parents combine diluted vinegar with cooled herbal tea, such as tulsi tea, and gently comb it through the coat. Avoid irritated skin, open wounds, the eyes, and the face.

Food-Grade Diatomaceous Earth

Food-grade diatomaceous earth is a fine powder made from fossilized algae. It works by drying out insects and may help reduce fleas and other pests when used in the environment.

Some people apply it directly to a pet’s coat, but it can be drying to the skin. For that reason, many pet parents prefer using it in the environment rather than directly on the dog.

Avoid inhalation. The dust can irritate the lungs, especially in pets with respiratory sensitivities. Use extra caution in homes with cats or pets with breathing issues.

Homemade Natural Sprays

Homemade flea and tick sprays can be part of a natural prevention plan when used safely.

Think of these sprays like bug spray for dogs. They may be applied before outdoor time and may need to be used consistently, often daily or before hikes, walks, or time in wooded areas.

Natural spray ingredients may include diluted lavender, tulsi tea, vinegar, or other dog-safe ingredients, depending on your dog’s needs and tolerance.

Lightly apply or comb through areas where fleas and ticks commonly attach, such as the legs, feet, belly, chest, neck, and tail base. Avoid the face, eyes, irritated skin, and open wounds.

Yard Care Can Make a Difference

Your yard can either invite pests in or make the environment less appealing to them.

Helpful steps include:

• Keeping grass short.
• Removing leaf piles and yard debris.
• Reducing cool, damp, shady areas.
• Allowing more sunlight into areas where your dog spends time.
• Keeping outdoor bedding and resting areas clean.

Some plants, such as lavender, rosemary, and marigolds, are often used in gardens and may offer some pest-discouraging benefits. Plants alone will not eliminate fleas or ticks, but they can be one part of a larger prevention strategy.

In some areas where it is practical and allowed, chickens may also help reduce tick populations because they naturally forage and eat insects, including ticks.

The Best Plan Is Individualized

There is no perfect flea and tick prevention plan for every dog.

Some families may choose conventional preventatives because their dog’s exposure risk is high. Others may choose a more natural approach because their dog is sensitive, medically fragile, or because they prefer to reduce chemical exposure when possible.

The best plan is the one that is safe, realistic, consistent, and appropriate for your individual dog.

Consider:

• Your dog’s age.
• Health status.
• Cancer status or immune concerns.
• Breed and coat type.
• Lifestyle.
• Local flea and tick risk.
• Sensitivity to products.
• Other pets in the home, especially cats.
• Your ability to maintain a consistent routine.

Work With Your Veterinarian

Before changing your dog’s flea and tick prevention routine, talk with your veterinarian. Flea and tick-borne diseases can be serious, and natural options may not be enough for every dog or every location.

If you prefer a more integrative approach, consider working with a holistic or integrative veterinarian who can help you weigh the risks and benefits and choose a plan that supports your dog’s safety.

A natural approach often includes keeping the environment clean, maintaining the yard, checking your dog’s skin and coat daily, using veterinarian-approved natural repellents when appropriate, and supporting your dog’s overall health.

Your dog deserves protection that is thoughtful, safe, and tailored to their needs.
