He had not been hired to do Deet
research, and it didn't matter whether he had discovered the cause of Gulf War syndrome or the cure for male pattern baldness: He was out of bounds.
Another strategy is to select a deet
product with a modest concentration of the chemical.
After application of both products, the Medella Naturals' formulation repelled greater than 90% of the bites through 5.5 hours post-application compared to the DEET
formulation that repelled at 40% beyond a 90 minute period.
The means of percentage protection for DEET
and TRIG was calculated as above and compared using Student's i-test.
Animal studies using large doses have shown that DEET
is not a specific neurotoxin, and while there have been case reports of central nervous system toxicity in humans, there is no link to DEET
dose or mechanistic pathway.
Deep Woods VIII, which contains 25% DEET
, kept Aedes mosquitoes from biting for approximately 8 hours.
Entomologist Joseph Dickens and his colleagues in the Invasive Insect Biocontrol and Behavior Laboratory discovered that a taste receptor located on a mosquito mouthpart is sensitive to DEET
For the best protection against both mosquitoes and ticks, the CDC recommends products containing DEET
. For just mosquitoes, the agency also approves of products with the active ingredients picaridin (the active ingredient in most Avon Skin So Soft products), IR3535, and oil of lemon eucalyptus which, despite its natural-sounding name, is actually a synthetic formulation, EWG found all three of these ingredients to be just as effective as DEET
and other insect repellents such as citronella are generally safe for individuals over 2 months of age.
, an effective ingredient of insect repellent, is widely used to prevent mosquito bites (Fradin & Day, 2002).
A newly discovered batch of bug repellents works just as well as DEET
, scientists report October 2 in Nature.
Citing research at Iowa State University, Care2 says essential oil in catnip, which drives cats wild, hence the name, is "about 10 times more effective than DEET
(diethyl-meta-toluamide, a popular anti-bug ingredient) in repelling mosquitoes."
