DEET is the most common ingredient in several types of insect repellants, but now there's word that chemical may affect the central nervous system. Researchers warn that DEET may be a potential danger to humans although they emphasize the need for more studies.

The findings are published in the current online edition of BMC Biology.

The experts emphasize that people should probably be more worried about the health risks from mosquitoes and other insect bites than DEET.
