There’s no lack of creative billboards in Brazil. However, the latest billboard innovation is particularly smart as it attracts, traps and kills mosquitoes that carry the Zika, dengue and chikungunya viruses. The billboard spreads a solution of lactic acid and CO2 that “replicates human sweat and breath,” which, according to its promoters, attracts mosquitoes from as far as 2.5 miles away. Fluorescent lights lure the bugs in further and then a vacuum device sucks them into the billboard, where they die of dehydration.
