The leaves and the bark of the tea tree have long been used by the Australian Aborigines to treat minor skin irritation and to keep parasites from the skin and hair. Today the essential oil is used as an effective remedy for many ailments.

The disinfectant, antibacterial, antiviral and fungicidal effects of tea tree oil help the body fight and relieve the symptoms of skin diseases. Besides working as a repellent against mites, ticks, fleas, and lice, those unwanted visitors can also be eliminated using tea tree oil.

Extraction of Tea Tree Oil

There are over 100 different substances that work together in tea tree oil and give the oil its biocidal properties that are effective against insects and ticks.

The oil consists largely of the terpenes (a type of essential oil): Terpinen-4-ol, α-terpinene, and cineole. The latter is considered an impurity. The level of cineole is low in high-quality tea tree oil.

Tea tree oil is inexpensive and non-toxic when used externally as recommended. It must NOT be taken internally and is NOT recommended for children. Always read the label and use tea tree oil only as recommended.

Home Made Tea Tree Tick Repellent Recipe

Tea tree oil should not be applied directly to the skin in large amounts. A drop on an insect bite to stop the itch is fine. But concentrated amounts may cause irritation. To use tea tree oil as a repellent it is best to dilute it in a mixture using a skin-friendly base oil like Jojoba or Coconut oil.

To rub on: Use coconut oil, jojoba, or avocado oil as a base oil for natural homemade insect protection. Take a cup of the base oil and mix properly with about 10 to 20 drops of tea tree oil. Rub onto skin if necessary. Don’t use it in your face and don’t get anything into your eyes. Remember to use a glass container to store your tick repellent.

As a spray: Mix half a cup of water with half a cup of rubbing alcohol and ten to twenty drops of tea tree oil. Fill the ingredients into a cleaned spray bottle and shake vigorously until everything has mixed together. Spray directly onto the skin, make sure nothing gets into your face and into the eyes. If you prefer to avoid alcohol, you can use witch hazel water.

To repel ticks, put 2 or 3 drops in the neck of the dog, just as recommended with conventional spot-on.

Dog Shampoo

You can fortify your regular dog shampoo by adding 6-10 drops of tea tree oil to every 2 oz. of shampoo. Wash your pet with this mixture ensuring that it gets into all areas where ticks are likely to hide for example behind the ears, under the tail, and in the armpits. You should let the pet soak in the shampoo for 10 minutes before drying up the excess. There are also ready-made pet shampoos available that contain Tea tree oil.

Cats and Tea tree oil

Tea tree oil is toxic to cats. It must NOT be used on cats. Since cats are very clean animals and permanently lick themselves in all parts of their body, Tea tree oil would enter their digestive tract. Tea tree oil contains terpenes and phenols, among others. Substances that the cat’s metabolism cannot digest or break down. As a result, they accumulate in the cat’s body and will cause poisoning, that can kill the cat.

Only a few natural repellents may be used on cats, very effective are chemical spot-on repellents especially made for cats.

In rare cases, Tea tree oil may cause skin irritation. To check for an allergic reaction before use, apply a very small amount to the skin inside your elbow area to test for any reaction. If a rash occurs consult your healthcare professional.

Tea tree oil is for external use only.

Avoid contact with eyes. Keep out of reach of children. If pregnant, consult with your doctor before use.
