The Environmental Protection Agency (EPA) announces, "A new active ingredient, discovered and developed by the Centers for Disease Control and Prevention (CDC), has been registered by the Environmental Protection Agency (EPA) for use in insecticides and insect repellents.
"Studies show that when products are formulated from the new ingredient, nootkatone, they may repel and kill ticks, mosquitoes, and a wide variety of other biting pests. Nootkatone is responsible for the characteristic smell and taste of grapefruit and is widely used in the fragrance industry to make perfumes and colognes. It is found in minute quantities in Alaska yellow cedar trees and grapefruit skin.
"Nootkatone can now be used to develop new insect repellents and insecticides for protecting people and pets. CDC’s licensed partner, Evolva, is in advanced discussions with leading pest control companies for possible commercial partnerships. Companies interested in developing brand name consumer products will be required to submit a registration package to EPA for review, and products could be commercially available as early as 2022."
When applied, it is able to repel ticks, mosquitoes, and other insects for hours. It is nontoxic to humans. Nootkatone is already used as an approved food additive, and is commonly used in products for human consumption.
