NEW Natural Oral Flea and Tick Prevention: Diatomaceous Earth, Brewer’s Yeast, and a DIY Flea Spray That Works

Plus My Homemade Flea Spray That Actually Works

Fleas can be so difficult to deal with.

And yes, they can survive just fine in December… especially inside your home.

I have seen how frustrating this can be for pet parents. You think you have it under control, then suddenly they are back again.

Conventional options can work quickly. But many contain pesticides, and repeated exposure to those chemicals should make you pause. We now know they can affect your pet at a deeper level, even influencing gene expression over time.

That is why I always encourage you to think more holistically when possible.


Dr. Jones’ Diatomaceous Earth Powder for Pets

For Natural Internal & External Parasite Control in Dogs and Cats Support your pet’s health the natural way with Dr. Jones’ Diatomaceous Earth Powder, a premium, organic food-grade powder specially formulated for safe use in both dogs and cats. OMRI Certified for organic use, this fine, white powder is a versatile and effective tool for promoting a parasite-free lifestyle—without the use of harsh chemicals or synthetic treatments.

A Simple Natural Option I Have Used for Years

One of my go-to remedies is diatomaceous earth.

I have used it in my garden to stop pests, in my home for fleas, and even given it orally to help with parasites.

It is:

  • Natural
  • Safe when food grade
  • Fairly effective when used consistently

Just make sure you are using food-grade diatomaceous earth, not the type used for pool filters.

Natural Oral Flea Prevention Options

1. Bioticks

This is a plant-based oral supplement made with ingredients like thyme, rosemary, lemongrass, fenugreek, and wormwood.

It works in a simple way. It changes your pet’s scent slightly, making them less attractive to fleas.

What I like about it:

  • Studies show flea reduction of over 80 percent in dogs
  • Works gradually over time
  • No reported side effects
  • Easy to give in food daily

It is a good long-term option, especially if you want to avoid chemical treatments.

2. Diatomaceous Earth

Also called chinchilla dust, this is made from microscopic algae skeletons.

You can:

  • Apply it lightly to your pet
  • Sprinkle it in your home
  • Vacuum after a few days

Use it weekly during flea season.

3. Make Your Pet Less Appealing to Fleas

Garlic and brewer’s yeast can help repel fleas.

In my experience, it helps in about 30 percent of pets. Not perfect, but worth trying.

For a 10 lb dog:

  • 1/4 teaspoon garlic
  • 1/4 tablespoon brewer’s yeast daily

Used in small amounts, garlic is safe for both dogs and cats.

4. Ultrasonic Devices

Devices like Tickless emit high-frequency sounds meant to repel fleas and ticks.

They are:

  • Chemical-free
  • Safe for young and pregnant pets

The science is mixed, but some pet parents do find them helpful.

My Natural Flea and Tick Spray Recipe

If you want something you can use right away, this is one of my favorite topical sprays.

Key Ingredients

Neem Oil
A natural insecticide with anti-inflammatory and antifungal benefits. Safe when diluted to 2 percent or less.

Cedarwood Oil
One of the most effective natural flea and tick repellents.

Coconut Oil
Helps soothe the skin and has mild insect-repelling properties.

Witch Hazel with Aloe
Supports skin health and reduces irritation.

Castile Soap
Helps kill fleas and allows the oils to mix properly.

The Recipe

  • Witch Hazel with Aloe: 1 cup (250 ml)
  • Coconut Oil: 2 tablespoons (30 ml)
  • Neem Oil: 2 ml
  • Cedarwood Oil: 40 drops
  • Castile Soap: 1 tablespoon (15 ml)

This keeps the essential oils at about 1 percent dilution, making it safe for dogs and cats.

How to Use It

  • Shake well before each use
  • Lightly mist your pet
  • Use a flea comb to spread it through the coat

Use:

  • 2 to 3 times per week for dogs
  • Once weekly for cats

If your home is cold, you may need to warm the mixture slightly so the oils stay liquid.

My Takeaway

There is no single magic fix for fleas.

The key is consistency and layering your approach.

  • Use natural oral support
  • Treat the environment
  • Apply safe topical solutions
  • Check your pet regularly with a flea comb

That is how you stay ahead of the problem.
