I’m sure we all can relate when I say, “I HATE MOSQUITOES”. They come in a giant wave in the summer and just love to make us itchy. There are a few people in my life who seem to have beaten mosquitoes at their game, but more on that later. Mosquitoes are notorious for their nuisance and the potential health risks they pose as vectors of various diseases. In the quest for effective mosquito repellents, citronella is an ever-popular choice in my household. Let me tell you what I’ve learned about citronella and how it can help you guys out.

Understanding Citronella

Citronella is a natural oil derived from the leaves and stems of certain species of plants, notably Cymbopogon nardus and Cymbopogon winterianus. It has a distinct aroma and is commonly found in candles, oils, sprays, and other commercial mosquito repellent products. Citronella is believed to repel mosquitoes by masking the scents that attract them, making it harder for these insects to locate and feed on human hosts. However, the scientific evidence supporting this claim remains inconclusive.

Scientific Studies

Several scientific studies have been conducted to evaluate the effectiveness of citronella as a mosquito repellent. While some studies have shown promising results, others have found limited or no repellent effects. A study published in the Journal of the American Mosquito Control Association in 2005 tested various commercial mosquito repellents and found that citronella-based products provided limited protection, with only a short duration of repellency. Similarly, a more recent study published in 2020 in the Journal of Insect Science reported that citronella-based repellents showed no significant effect in deterring mosquitoes. These findings highlight the need for further investigation and highlight the inconsistencies in the effectiveness of citronella as a mosquito repellent.

Limitations and Factors

Several factors influence the effectiveness of citronella as a mosquito repellent. The concentration of citronella oil in a product plays a crucial role, as higher concentrations tend to provide better protection. However, many commercial products contain low concentrations of citronella, which may contribute to their limited efficacy. Additionally, individual variations in human attractiveness to mosquitoes, environmental conditions, and mosquito species can also impact the effectiveness of any repellent, including citronella. Moreover, the duration of protection offered by citronella-based products tends to be shorter compared to other mosquito repellents such as DEET, requiring more frequent reapplication.


While citronella has long been regarded as a natural mosquito repellent, scientific evidence regarding its effectiveness remains inconclusive. While some studies have shown limited efficacy, others have found no significant deterrent effect against mosquitoes. Factors such as product concentration, individual attractiveness, and environmental conditions influence the effectiveness of citronella-based repellents.


To maximize protection against mosquitoes, it is advisable to consider alternative repellents backed by more robust scientific evidence, such as DEET or picaridin. If you don’t want harsh chemicals on your skin, I’ve got a secret for you that has blown my mind. A close friend of mine who actively serves in the United States Marine Corpse has a trick that keeps mosquitos away, is easy to purchase, and smells really good. Go to the store and get yourself some DRYER SHEETS. You know, the little pieces of cloth like paper you throw into your dryer so your clothes feel soft and aren’t super staticky. Yes, grab a couple of dryer sheets. Put them in your socks, cuffs, shirt pockets, and collars and it will make a world of difference. You get to smell amazing and the mosquitoes will hate it and leave you alone.
