A Duke University Medical Center pharmacologist is advising to be careful when using the insecticide DEET, after his animal studies last year found the chemical causes diffuse brain cell death and behavioral changes in rats after frequent and prolonged use.
The Duke University Medical Center has concluded through laboratory rat studies that long-term use of DEET kills brain neurons. DEET can cause neurological damage, and once it enters the bloodstream, it reaches the nervous system, where it is known to cause seizures and even death.
Rats treated with an average human dose of DEET – 40 milligrams per kilogram body weight – performed far worse than control rats when challenged with physical tasks requiring muscle control, strength and coordination.
French scientists from the Institut de Recherche pour le Developement in Montpellier and Bruno Lapied from the University of Angers headed a team of researchers who studied the mode of action and toxicity of DEET, stated, “We’ve found that DEET is not simply a behavior-modifying chemical but also inhibits the activity of a key central nervous system enzyme, acetycholinesterase, in both insects and mammals.”
