In this article, we will explore how essential oils can be used to create effective insect repellents for you and your yard, ensuring a more enjoyable and harmonious outdoor experience.

What are essential oils?

Essential oils are highly concentrated natural oils extracted from certain plants that capture the scent and beneficial properties of their source. They have long been used for their aromatic and medicinal benefits, including their effectiveness as insect repellents.

How do essential oils repel insects?

Essential oils contain volatile compounds such as terpenes, phenols, and ketones, which have insect-repelling properties. Different essential oils can repel a wide range of insects, including mosquitoes, flies, ticks, fleas, ants, and moths.


Are essential oils safe to use around my family and pets?

Essential oils are generally safe for humans, pets, and the environment when used correctly. Unlike chemical insecticides, essential oils leave a pleasant and often therapeutic scent. Essential oils can be used in various forms, including sprays, lotions, diffusers, and candles. Many essential oils have antimicrobial properties, adding an extra layer of protection against pathogens.

Which essential oils can be used as insect repellent?

Below are just a few essential oils that work well as insect repellent. Mix and match them to find the best combination for you.

1. Eucalyptus oil

Eucalyptus oil is renowned for its insect-repellent properties, primarily due to its high content of eucalyptol (also known as cineole), which constitutes about 70-90% of the oil. This compound is the key to its effectiveness in keeping bugs at bay. The oil emits a strong, distinctive aroma that is fresh, camphoraceous, and slightly medicinal. While this scent is pleasant to humans, it is offensive to many insects, making eucalyptus oil a natural and non-toxic alternative to synthetic chemical repellents.


Unlike conventional chemical repellents, eucalyptus oil is free from harmful substances, making it a safer choice for both humans and pets when used properly. Its natural composition provides peace of mind to those looking for effective yet eco-friendly insect repellent options. Additionally, eucalyptus oil is not limited to repelling just one type of insect; it is effective against a wide range of pests, including mosquitoes, ticks, fleas, flies, and even some types of ants.


The dual benefits of eucalyptus oil make it a popular choice for those seeking both functionality and a pleasant experience. Its strong, refreshing aroma is enjoyable for most people, adding an extra layer of appeal. By using eucalyptus oil, you can effectively repel insects while also enjoying the invigorating scent it leaves behind.

2. Tea tree oil

Tea tree oil is packed with active compounds, with terpinen-4-ol being the most prominent. These compounds give tea tree oil its strong antimicrobial and insect-repelling properties.

As a natural substance, tea tree oil is free from the harmful chemicals often found in synthetic repellents, making it a safer option for both humans and pets when used correctly. This natural composition provides a sense of security for those seeking effective, eco-friendly insect repellents.

One of the standout features of tea tree oil is its dual functionality. Besides repelling insects, it can also help treat and soothe the skin after insect bites, reducing itching and inflammation. This makes tea tree oil a versatile addition to your natural insect repellent arsenal, offering both prevention and relief in one product.

3. Peppermint oil

Peppermint oil is rich in active compounds, with menthol and menthone being the most prominent. These compounds are responsible for peppermint oil's strong, minty aroma and its effective insect-repellent properties. The oil's fresh and minty scent is pleasant to humans but highly repulsive to many insects. Additionally, peppermint oil has a cooling effect on the skin, helping to soothe irritation and inflammation, making it useful for treating insect bites.

The Ginkgo Tree

By Victoria Smith • May 16, 2025
Ginkgo biloba , commonly known as the maidenhair tree, is native to China and is one of the oldest living tree species—often referred to as a "living fossil." Ginkgo trees are easily recognized by their distinctive fan-shaped leaves, which turn a brilliant yellow in the fall. They are highly tolerant of pollution, pests, and poor soil, making them well-suited for urban environments. Ginkgo trees typically grow 50 to 80 feet tall, though some can exceed 100 feet. Young trees have an upright, pyramidal shape that broadens with age. Their leaves feature split veins in a fan-like pattern, and their bark is smooth when young, becoming furrowed as the tree matures. Ginkgos are hardy in USDA zones 3 through 9.
