According to a study published in the Journal of Experimental Biology, mosquitoes may seek out the scent of the repellent.
Scientists believe DEET protects people by masking the carbon dioxide that we emit, making it harder for biting insects to detect us. However, “If someone applies DEET and the concentration fades over time, but a mosquito still manages to feed, the insect may begin associating that smell with a reward,” explained Clément Vinauger, PhD.

Instead of applying a lot at once, you may want to reapply regularly so it’s always active and providing continuous protection.” Clément Vinauger, PhD
INSIGHTS: Animal health pros are familiar with concentration-dependent versus dose-dependent products. This study may set the stage for different evaluations of premise products and those we use around our animals.
