Study finds catnip oil as effective alternative to Deet for mosquito protection
A study involving researchers from Wales and Uganda has identified a locally sourced catnip oil as an effective repellent against mosquitoes. The findings suggest that this plant-based solution could provide a more affordable alternative to standard chemical treatments like Deet.

Researchers from Wales and Uganda have identified a local source of catnip as an effective way to repel mosquitoes in rural regions of Uganda. The study, reported by both The Guardian and Phys.org, involved the development of a homegrown oil intended for use as a repellent. This research was conducted as part of a community enterprise project aimed at providing affordable protection against mosquito-borne illnesses.
The findings indicate that catnip oil performs comparably to Deet, which is currently the standard chemical repellent used globally. According to reports from both The Guardian and Phys.org, researchers tested various concentrations of the plant oil to determine its efficacy. Their data showed that a 6% concentration of catnip oil was just as effective at repelling mosquitoes as Deet, while a 2% concentration was found to be only marginally less effective than the synthetic chemical.
The use of local botanical resources is intended to provide an accessible solution for residents in rural areas. Because chemicals like Deet can be expensive or difficult to source in remote locations, the discovery of a locally available and cost-effective option may have practical implications for community health. The study highlights how plant-based products can serve as viable alternatives to synthetic chemical compounds in specific regional contexts.
The project was a collaborative effort between Welsh and Ugandan researchers focused on botanical science. By utilizing local plants, the study aims to establish a sustainable model for repellent production. While Deet remains a primary global standard, the results from this research indicate that catnip oil is a robust alternative for rural applications.
Why this matters
The discovery offers a potentially low-cost, locally sourced method for mosquito protection in regions where malaria and other mosquito-borne diseases are prevalent. It provides a practical model for using local botanical resources to address public health challenges in areas with limited access to imported chemicals.
What's confirmed / what isn't
The primary findings regarding the effectiveness of catnip oil compared to Deet are consistently reported by both The Guardian and Phys.org. Specific details regarding the 6% and 2% concentration results were also noted in reports accompanying the study.
Background
Deet (N,N-Diethylmetanilamine) is a common chemical repellent used globally to prevent bites from insects such as mosquitoes and ticks.
