7 Natural Ways to Repel Mosquitoes & Enjoy Summer

Warmer weather invites outdoor activities, but often comes with an unwelcome guest: the mosquito. These persistent pests can quickly disrupt enjoyment of summer days. Fortunately, several natural methods can help deter mosquitoes, allowing people to reclaim their outdoor spaces.

Understanding Mosquito Repellents

When considering natural repellents applied to the skin, choosing products registered by the Environmental Protection Agency (EPA) is crucial, according to Joseph Conlon, a retired U.S. Navy entomologist and technical adviser for the American Mosquito Control Association. Individuals with sensitive skin or known allergies should test any essential oil on a small area of the forearm before widespread use.

Did You Know? Catnip oil, specifically its active ingredients called nepetalactones, has been shown in laboratory tests to effectively repel Aedes aegypti, the yellow fever mosquito.

Lemon Eucalyptus: A Recommended Option

The Centers for Disease Control and Prevention recognizes lemon eucalyptus as an active ingredient in mosquito repellents. Conlon describes it as “a very good repellent,” but cautions against its use on children under 3 years old, as it hasn’t been approved for that age group.

The Power of Plant-Based Oils

Research indicates several plant-based oils can effectively repel mosquitoes. A 2024 study demonstrated the effectiveness of catnip oil, providing up to seven hours of protection, according to Conlon. Cinnamon oil, tested against Aedes aegypti, offered over an hour of complete protection, comparable to clove oil. Clove oil itself is noted for providing longer protection than many other essential oils.

Beyond Oils: Smoke and IR3535

Smoke from plant-based coils, incense, and fire pits can reduce mosquito activity by disrupting their sensory cues. This method is most effective in open or semi-outdoor areas, especially when combined with airflow. Additionally, IR3535, a synthetic amino acid found in many cream-based repellents, interferes with a mosquito’s sense of smell and provides up to eight hours of protection with no toxicity, according to Conlon.

Expert Insight: The effectiveness of these natural methods often relies on consistent application or environmental factors like airflow, suggesting a multi-faceted approach may be most successful in managing mosquito populations.

Eliminating Breeding Grounds

Preventing mosquito breeding is a critical step. This includes unclogging roof gutters, emptying children’s pools, changing bird bath water weekly, ensuring trash can lids don’t collect rainwater, and storing unused containers upside down.

How long can catnip oil protect against mosquitoes?

According to Conlon, catnip oil can provide up to seven hours of protection from mosquitoes, and is EPA-approved.

Is IR3535 a natural repellent?

IR3535 is a synthetic amino acid, not a natural repellent, but it is considered non-toxic and provides up to eight hours of protection, according to Conlon.
