Fleas and ticks can be a constant nuisance for pets and their owners. While chemical treatments are available, many pet parents prefer natural methods to keep these pests at bay. Fortunately, nature provides an array of foods that have anti-parasitic properties, helping to repel fleas and ticks from the inside out. Incorporating these into your pet’s diet can help support a healthier, pest-free life. Here are five natural anti-parasitic foods to consider.

Garlic (in Small, Safe Amounts)

Garlic has long been known for its natural repelling effects against fleas and ticks. While large amounts of garlic can be toxic to dogs and cats, small, controlled portions are considered safe and beneficial. Garlic contains sulfur compounds that are released through the skin when ingested, making pets less attractive to pests. Always consult your veterinarian about the correct dosage for your pet before adding garlic to their diet.

Apple Cider Vinegar

Apple cider vinegar (ACV) is a well-known natural remedy with antimicrobial properties. When added to a pet’s drinking water in small amounts, ACV helps maintain a balanced pH level, making their skin less hospitable to fleas and ticks. A simple mix of one teaspoon of ACV per quart of water can aid in repelling pests while also supporting digestion and immune health.

Pumpkin Seeds

Pumpkin seeds are not only a nutritious snack but also an effective natural dewormer. They contain an amino acid called cucurbitacin, which paralyzes and expels intestinal parasites from the body. Additionally, pumpkin seeds can contribute to overall health by providing essential fatty acids and antioxidants. Ground pumpkin seeds can be sprinkled over your pet’s food for an easy and beneficial anti-parasitic boost. Try Beef Topper with Carrots and Blueberries (on Amazon), which contains pumpkin for added benefits.

Coconut Oil

Coconut oil is a powerhouse when it comes to natural parasite control. It contains lauric acid, a compound known for its antimicrobial and flea-repelling properties. Feeding pets a small amount of coconut oil can improve skin and coat health while creating an internal environment that is less attractive to fleas and ticks. Additionally, coconut oil can be applied topically to soothe irritated skin and deter pests. Consider using Organic Chicken Bone Broth Powder (on Amazon) as a nutritious supplement alongside coconut oil for overall pet wellness.

Brewer’s Yeast

Brewer’s yeast is another excellent flea and tick deterrent. This nutritional supplement is rich in B vitamins and can help strengthen a pet’s immune system while naturally repelling fleas. When ingested, it creates an odor on the skin that is undetectable to humans but unappealing to fleas and ticks. Adding a small amount of brewer’s yeast to your pet’s diet can be an effective and natural way to keep parasites at bay. A great option to consider is Glucosamine and Turmeric Chews (on Amazon), which provide additional joint health benefits along with their nutritional content.

By incorporating these natural anti-parasitic foods into your pet’s diet, you can help reduce the risk of fleas and ticks without relying on harsh chemicals. While natural remedies can be effective, they work best when combined with proper grooming, a clean living environment, and regular veterinary check-ups. Keeping your pet healthy from the inside out is key to a pest-free, happy life. Disclosure: As an Amazon Associate, iHeartDogs earns from qualifying purchases.
