Washington, DC–(ENEWSPF)–February 26, 2013. The world’s most commonly used synthetic insect repellent is not as effective as it once was, according to scientists at the London School of Hygiene and Tropical Medicine. While researchers found DEET to be an effective repellent after an initial application, subsequent rounds of testing mere hours later showed mosquitoes to be unaffected by its presence. The study, published in the journal PLOS One, underlines the need to develop safe, natural, effective alternative prevention s to this hazardous chemical.
