Study compares insect repellents and rates their effectiveness

The Zika virus has made many people more aware of the need to wear repellents. Consumer Reports tested several DEET-based and natural repellents and recommended several brands in their April issue. In addition, in 2015, a group of researchers from New Mexico State University also tested several DEET-based and natural repellants, along with a bath oil, one perfume and a skin patch to compare a more varied group of products.

The peer-reviewed article, which appeared in the Journal of Insect Science in 2015, compared ten “repellents” to a control. Three DEET-based products were tested, including the popular OFF Deep Woods repellent, in addition to four natural repellents, two fragrances and a mosquito skin patch containing Thiamin B1.

DeLaune, a Texas A&M AgriLife Research environmental soil scientist in Vernon, said he has compared no-till, strip till and conventional till, as well as cotton with a terminated wheat crop in the Rolling Plains. Continue reading
