As spring and summer invite more time outdoors, they also bring an increase in ticks, mosquitoes and other biting insects. For many people, avoiding itchy bites is only part of the concern. Growing awareness around tick-borne illnesses such as Lyme disease has heightened interest in effective insect protection, while others simply seek more natural ways to stay comfortable during the warmer months.

Many conventional insect repellents contain synthetic chemicals that some consumers prefer to avoid on their skin and around their families. Fortunately, research continues to explore the insect-repelling properties of certain essential oils, many of which demonstrate promising effects against ticks and mosquitoes alike.

When properly diluted in a carrier oil, essential oils can offer a more natural alternative for those looking to reduce chemical exposure while spending time outdoors. High-quality oils matter, however. Certified pure therapeutic-grade oils and nourishing carrier oils such as coconut oil are generally preferred for both safety and skin compatibility.

Blending Oils for Better Protection

Research and anecdotal experience suggest essential oil combinations may perform better than single oils alone. Popular blends include:

• Citronella, cedarwood and lavender
• Lemongrass, peppermint and geranium
• Clove, citronella and rosemary

Because ticks and mosquitoes respond differently to various compounds, combining multiple oils may offer broader-spectrum protection.

DIY Natural Tick and Mosquito Repellent

This simple recipe combines several essential oils commonly associated with both tick and mosquito repellency. IIt can be used oustide anytime: when gardening, working in the yard, hiking or simply enjoying an evening on the lake or by the fire.

Ingredients

• 1 to 2 ounces coconut oil or fractionated coconut oil
• 10 drops lemongrass essential oil
• 10 drops citronella essential oil
• 5 drops clove essential oil
• 5 to 10 drops thyme essential oil
• 10 drops lavender essential oil

Optional Additions

• 5 drops oregano essential oil
• 5 drops geranium or ylang ylang essential oil
• 5 to 10 drops cedarwood essential oil
• 5 to 10 drops peppermint essential oil

Directions

Combine the lemongrass, citronella, clove, thyme and lavender essential oils with 1 ounce of coconut oil. If adding additional oils, increase the carrier oil by approximately one-half ounce. Those with sensitive skin may prefer diluting the blend into a full 2 ounces of carrier oil.

Once mixed, transfer the blend into a glass roller bottle or small glass bottle if using fractionated coconut oil. If using solid coconut oil, store in a small glass jar.

Essential Oils With Research-Backed Repellent Properties

Several essential oils have demonstrated effectiveness in laboratory and behavioral studies against ticks and mosquitoes.

Top Essential Oils for Ticks

Clove bud oil
One of the strongest performers in studies, clove oil has shown repellency rates of more than 80 percent at relatively low concentrations. Its high eugenol content contributes to its potency.

Thyme oil
Particularly red thyme and creeping thyme varieties have demonstrated strong tick repellency, with some studies showing effectiveness ranging from approximately 68 to 82 percent.

Citronella oil
Widely recognized for mosquito protection, citronella also demonstrates notable repellency against ticks and may remain effective for several hours.

Lemongrass oil
Research suggests lemongrass oil significantly discourages tick activity and attachment behaviors.

Oregano oil
In some experiments, oregano oil reduced tick attachment to treated clothing and surfaces.

Other oils with moderate evidence for tick repellency include lavender, peppermint, rosemary, cedarwood, eucalyptus, juniper and geraniol-rich oils such as geranium.

Natural Mosquito Repellents

Certain essential oils appear particularly effective against mosquitoes.

Oil of lemon eucalyptus, specifically products containing PMD (p-menthane-3,8-diol), has some of the strongest scientific support among natural mosquito repellents and is recognized by the U.S. Centers for Disease Control and Prevention. It is important to note that OLE differs from standard lemon eucalyptus essential oil.

These classic outdoor scents help mask the body’s natural chemical signals that attract mosquitoes. They are commonly used in sprays, candles and outdoor products.

Lavender provides mild mosquito repellency while also offering calming and skin-soothing properties.

The strong scent of peppermint may deter mosquitoes while also providing a cooling sensation that can soothe irritated skin.

Rose geranium oil contains geraniol, a compound frequently used in natural insect repellents. Cedarwood blends well with citronella and lavender while helping repel multiple insect species.

Some studies suggest catnip oil may be surprisingly effective against mosquitoes due to its nepetalactone content.

Safety Tips for Natural Repellents

Even natural products require thoughtful use.

• Always dilute essential oils before applying to skin.
• Reapply every one to two hours, especially during heavy insect exposure.
• Perform a patch test before widespread use.
• Avoid contact with eyes and mucous membranes.
• Some essential oils may not be suitable for young children, pets or pregnancy.

Natural repellents may not provide the same duration of protection as conventional products, particularly in areas with heavy tick or mosquito populations. Wearing protective clothing, checking for ticks after outdoor activities and avoiding standing water remain important preventive measures.

For those seeking a more plant-based approach to outdoor wellness, however, essential oil blends may offer a practical and pleasantly aromatic addition to summer adventures.
