Mosquitoes are both a nuisance and a vector of pathogens to humans and animals. Control of adult mosquitoes relies on insecticides and repellents. Here we describe developing and evaluating a natural product with potential as a spatial repellent against a variety of mosquito species including Aedes aegypti and Anopheles quadrimaculatus. The results demonstrate repellency and knockdown/mortality effects on lab colony strains of multiple mosquito species.
