Which Bugs Does Tea Tree Oil Repel?
Tea tree oil has a proven effect against bed bugs, lice, mosquitos, ticks, flies, bush flies and biting midges, otherwise known as sandflies.

It also helps keep ants out of your home and garden, and flies don’t seem to like the smell either—perfect for making outdoor activities more enjoyable.

Is tea tree oil safe to use on children or pets when used as a bug repellent?
Tea tree oil can work as a bug repellent for kids and pets, but you need to be careful and always dilute it properly.
- For kids, mix 1-2 drops of tea tree oil with a tablespoon of carrier oil, like coconut or almond oil, to get a 0.5%-1% concentration.

- For pets, it’s super important to dilute it even more since animals, especially cats, can be sensitive to essential oils. A 0.1%-0.5% dilution is best to keep it safe.
Always do a patch test before using it widely to check for skin irritation, and check with a pediatrician or vet if you’re unsure. Never use undiluted tea tree oil directly on skin or fur—it can cause irritation or an allergic reaction, especially on sensitive skin.

What Other Essential Oils Can Be Combined with Tea Tree Oil to Keep Bugs Away?
Tea tree oil is a great natural way to keep bugs away on its own, but mixing it with different essential oils can make it even more effective.
- Citronella Oil: A popular choice because its strong scent works wonders against mosquitoes and other pests.
- Lemon Eucalyptus Oil: This is another great option—it’s natural, smells fresh, and does a solid job of repelling bugs.

- Lavender Oil: It not only smells amazing but also helps ward off moths and mosquitoes.
- Peppermint Oil: It has a cool, minty scent, is perfect for tackling ants and spiders.
When making your bug-repellent mix, be sure to dilute the oils with a carrier oil and test it on a small area first to make sure it’s safe and works well.
How should this bug spray be stored to maintain its potency?
To keep your tea tree oil bug repellent effective, store it in a cool, dark spot, away from sunlight and heat. Light and heat can break down the essential oils and make them less effective. Use an airtight container, like a dark glass bottle, to protect it from oxidation and keep its properties intact.

Make sure the bottle is sealed tightly after each use to avoid exposure to air and moisture. And, of course, keep it safely out of reach of kids and pets!

Tea tree oil is particularly effective against certain insects like mosquitoes, flies, and ants. However, it may not repel every type of bug, so it’s often combined with other essential oils for broader effectiveness.
When properly diluted, tea tree oil bug repellents are usually safe to use on clothing. However, it’s recommended to test on a small, inconspicuous area first to ensure it doesn’t cause staining.
The effectiveness of tea tree oil bug repellent can vary, but generally, it should be reapplied every couple of hours, especially if you are sweating or after being exposed to water.
While tea tree oil is considered natural, it can be toxic if ingested and may irritate sensitive skin. Always consult with a healthcare professional before using it on children or around pets, and avoid direct application on pets.
Tea tree oil should always be diluted before applying to the skin, as undiluted oil can cause irritation in some people. A properly formulated bug repellent spray or lotion is safe when diluted correctly.
