New Natural Cedar Insecticide May Be Too Expensive To Produce
It’s about TIME!!! I read this fascinating story on NPR here.
An all-natural insect repellant called nootkatone found in Alaska yellow cedar trees and citrus fruits (like grapefruit) is being developed by the CDC. It is so safe for humans, it is even an FDA-approved food additive.
Nootkatone is not only safe for humans and the environment, it is a highly effective insect repellant. In fact, it is not only a bug repellant, but an insecticide causing death to biting insects like mosquitoes within 15 seconds.
Application of 2% nootkatone will also control ticks for up to 42 days at greater than 97 percent efficacy.
It is non-greasy, dries very quickly, and it has a very pleasant, citrus-y grapefruit odor to it.
Sounds too good to be true… But it is true! The only downside right now is that it is not available in the market, mainly because it is expensive — $4,000 per kilogram for highly purified food-grade material, which is used in parts-per-million amounts as a flavoring agent.
However, there are two companies that are currently working to make it available as insect control, hopefully in the near future!

GE Health donated time on their latest CT and MR systems for researchers from the Field Museum in Chicago to image the insides of an ancient baby mammoth. Lyuba, apparently one of the finest preserved mammoth specimens, was found by a Siberian reindeer herder three years ago. Now, thanks to modern technology, the researchers believe they know the cause of death of the mammoth. Lyuba is currently on view at the “Mammoths and Mastodons: Titans of the Ice Age” exhibit at the Field Museum. Of course, there’s also something to be said for today’s tomography scanners with bore sizes that can accommodate a mammoth.
