The Hunt for Next Generation Insect Repellents

 We were kinda hoping for some new nano-sized snout pluggers

American researchers have identified several new potential insect repellents that are three times more potent than DEET, the active ingredient in most tick and insect repellents, according to a new study.

In laboratory tests, the new compounds protected human volunteers from mosquitoes two to three times longer than DEET, (n,n-diethyl-m-toluamide), which has served as the gold standard of repellents for more than 50 years.While DEET repellents offer broad-based protection from a variety of insects, mosquitoes continue to spread diseases and some mosquitoes can bite through an application of DEET.

“It would be good to have more effective repellents that protect against a greater number of insect species,” said Ulrich Bernier, a research chemist with the Mosquito and Fly Research Unit of the US Department of Agriculture (USDA) who worked on the project.

Back in the 1940s, it took scientists a decade to screen 40,000 compounds in a search for new insect repellents. That quest ultimately led them to DEET. This time around, experts were able to screen thousands of compounds in a matter of months using a computer program.
