When it comes to keeping away the mosquitoes that can carry disease-causing viruses like Zika, not all repellents are created equally.
Researchers at New Mexico State University reported in the Journal of Insect Science that products containing DEET or oil of lemon eucalyptus were the most effective at repelling the Aedes aegypti mosquito, which can carry the Zika virus, as well as chikungunya, yellow fever and dengue.
The study tested five wearable devices, five sprays and one candle, using human volunteers.
Of the wearable devices, only OFF! Clip-on was effective, with just 27.14 percent of the mosquitoes attracted to the wearer. None of the others had any discernible effect, and neither did the citronella candle.
