Does Citronella Repel Mosquitoes? Unveiling the Truth Behind this Natural Repellent

Mosquitoes, the tiny blood-sucking pests that can turn a pleasant outdoor evening into an itchy nightmare, have prompted countless quests for effective repellents. Among these, citronella has emerged as a popular natural remedy. In this blog post, we will delve into the world of citronella to uncover whether it truly lives up to its reputation as a mosquito repellent.

What is Citronella?

Citronella is an essential oil derived from the leaves and stems of certain varieties of Cymbopogon grasses. This oil has a distinct lemony aroma and has been used for centuries in various cultures for its versatile properties. While it finds its place in perfumes, soaps, and culinary creations, it is most renowned for its role as a mosquito repellent.

The Science of Citronella

Citronella's mosquito-repelling prowess lies in its chemical composition. It contains compounds like citronellal and citronellol, which create a scent that mosquitoes find unpleasant. When applied, citronella masks the carbon dioxide and body odors that attract mosquitoes, making it harder for them to locate their prey.

Numerous scientific studies have examined citronella's effectiveness. While it may not be as potent as chemical repellents, it does show a degree of efficacy in keeping mosquitoes at bay, particularly when used in the right concentrations.

Citronella Products

Citronella is available in various forms, including candles, sprays, lotions, and oils. These products are easy to find and offer consumers a range of choices for mosquito protection. Many people swear by citronella candles for outdoor gatherings, as the flickering flames add ambiance while keeping mosquitoes away.

User experiences with citronella products are mixed. Some report significant relief from mosquito bites, while others find the effect less consistent. Individual preferences and environmental factors can influence the outcome.

Citronella vs. Other Mosquito Repellents

Comparing citronella to other mosquito repellents reveals its strengths and weaknesses. While DEET-based repellents remain highly effective, citronella offers a more natural alternative. However, it's important to note that citronella may not provide as long-lasting or comprehensive protection in heavily infested areas.

When choosing between citronella and other natural options like lemon eucalyptus or lavender, consider personal preferences and sensitivities, as well as the specific mosquito species in your region.

Factors Affecting Citronella's Effectiveness

To maximize citronella's effectiveness, consider the concentration of citronella in the product, the method of application, and the duration of protection. Higher concentrations generally provide better results, and reapplication may be necessary, especially in humid or rainy conditions.

Citronella Myths and Misconceptions

There are several myths surrounding citronella, such as its ability to repel all mosquito species or provide immediate protection. It's important to clarify these misconceptions to set realistic expectations for users.

Citronella Safety Concerns

While generally safe, citronella products can cause allergic reactions or skin sensitivities in some individuals. Take precautions, especially when applying on children or pets. Always follow product instructions for safe usage.

DIY Citronella Solutions

For those who prefer a hands-on approach, making homemade citronella candles or sprays can be a fun and cost-effective way to harness its repellent properties.

Citronella's Environmental Impact

Consider the sustainability of citronella production and its impact on non-target species when using these products. Eco-conscious consumers may explore alternatives or support sustainable citronella production practices.


In conclusion, citronella does have some effectiveness as a mosquito repellent, particularly when used in the right conditions and concentrations. While it may not offer the same level of protection as chemical repellents, it remains a valuable natural option for those seeking an eco-friendly alternative.
