We love horses here at Cedarcide. So much so, in fact, we’ve rescued 7 of them from kill pens as part of the Cedarcide Horse Rescue. The strength, grace and kindness of these majestic animals is a source of inspiration for us every day!

Occasionally we’re asked: “Is Cedarwood oil toxic to horses?” The short answer is No—when properly formulated and properly used, cedarwood oil is not toxic to horses. But there’s more to be said on the topic. Let us explain.

Cedarwood Oil And Horses

It’s important to note that you should never use full-strength essential oils directly on your horse’s coat—that includes cedarwood oil. Undiluted essential oils can be irritating to horses’ skin, and “hot” essential oils—which includes cassia, cinnamon bark, clove, hyssop, lemongrass, ocotea, oregano, and thyme—can actually cause mild burns and rashes at high doses. When it comes to cedarwood oil specifically, some species of cedar—like Western red cedar and white cedar for example—are naturally toxic and irritating, and should never be used in topical horse products.

How is Cedarcide Cedarwood Oil Different?

Firstly, Cedarcide products never contain toxic species of cedar. Secondly, because we only use the highest quality cedarwood oil sourced from pet-safe cedar trees (Juniperus ashei, to be specific), our products are always non-toxic, naturally sourced, and safe for horses. Using a multi-step filtration process, our cedarwood oil is purified of all unnecessary contaminants and other potentially harmful ingredients. However, as with any topical product, we suggest testing your horse for possible sensitivity or allergy to cedarwood oil with a light initial application.

How to Use Cedarcide BUG SPRAYS For Horses

We offer four products for horses and horse owners: Our naturally sourced Cedarcide All-Purpose Bug Spray, our extra strength insect spray, Tickshield, and our concentrated pest control bathing solution, Vet’s Choice.


We’ve found that some horses dislike being sprayed. For whatever reason, the spraying or spritzing action can occasionally frighten some horses. For this reason we recommend approaching your first application of Cedarcide All-Purpose Bug Spray or Tickshield with caution. If you find your horse dislikes being sprayed, simply apply your chosen solution by misting your hands and massaging the spray into their coat.

If the spraying action does not bother your horse, apply Cedarcide All-Purpose Bug Spray or its extra strength counterpart, Tickshield, by misting your horse all over—including armpits, underbelly, and around the ears and tail. Do not spray your horse’s face. Instead, spray the solution into your palms, and apply it to the face using your hands. Regularly treating your horses with Cedarcide All-Purpose Bug Spray  or Tickshield will kill and provide protection against additional ticks, mosquitoes, flies, mites, gnats, ear mites and other biting insects.

Tips for Using Vet’s Choice on Horses

Vet’s Choice is an extra strength and highly versatile concentrate designed to control insects and parasites commonly found on pets and livestock. Vet’s Choice kill and repels fleas, ticks, mosquitoes, mites and other biting insects. Vet’s Choice can be mixed with water for use as a bath, spray or dip. It can also be used in stables and barns to reduce flying insects, or used as a treatment for mange and several other common skin disorders.

If you plan to spray your horse directly, use 4 oz. of Vet’s Choice per each gallon of water. For a bath, we suggest mixing 2 oz. of Vet’s Choice per each gallon of water. For a dip, use a 1:200 ratio of Vet’s Choice to water.
