According to the Centers for Disease Control and Prevention (CDC), scientists have found a new way to repel and kill ticks and mosquitoes using a natural ingredient found in grapefruit and snow trees. spare. Nootkatone, the ingredient responsible for the smell and taste of grapefruit, and found in some fragrances, can repel and kill ticks, mosquitoes and other biting pests, according to a CDC newsletter. .
“Studies show that when nootkatone is formulated as an insect repellant, they can provide protection from the bite at the same rate as products with other readily available active ingredients and may provide protection. up to several hours, ”said the CDC statement. Nootkatone, registered by the Environmental Protection Agency (EPA) for use in insecticides and insect repellants after it was discovered and developed by the CDC, according to the statement.

“CDC is proud to have led the research and development of nootkatone,” said Jay C. Butler, MD, Deputy Director of Infectious Diseases. “Providing new alternatives to existing methods of bite prevention paves the way to tackling one of the biggest challenges in preventing vector-borne diseases ̵1; preventing bites.”
Nootkatone will be used to develop new insecticides and repellants to help protect people and pets from insect bites, the federal agency said. Pest control companies are in discussions with Evolva, CDC’s licensed partner, on developing a commercial partnership. Commercial products can appear as early as 2022.
“This new active ingredient has the potential to be used in insect repellents and pesticides in the future to protect people from disease. In many areas of the United States, mosquitoes have become resistant to existing insecticides. A new active component in our toolbox helps with vector control programs. “Alexandra Dapolito Dunn, EPA Administrator for the Office of Chemical Safety and Pollution Prevention, said in the newsletter.
The CDC says the number of reported cases of mosquito-borne and tick-borne diseases has doubled between 2004 and 2018, and tick-related diseases account for nearly 8 out of 10 of all cases. due to vector transmission is reported in the US.
