‘Sweaty’ billboard kills Zika-carrying mosquitoes (VIDEO)

A new billboard in Rio de Janeiro, Brazil is mimicking human sweat in order to lure and kill dangerous Zika-transmitting mosquitoes.

The revolutionary billboard attracts mosquitoes with fluorescent lights, emits carbon dioxide to resemble human breathing and a lactic acid-laced mist which mimics human sweat.

The combination of breath and sweat can lure mosquitoes from up to 4km (2,5 miles) away.

Once the blood-thirsty insects crawl into the sign, they become trapped and eventually die.

Designed by two Brazilian advertizing agencies, Posterscope and NBS, the companies have made the ‘technical blueprint’ available for anyone who wants to build their own mosquito-killing sign.

The agencies claim the sign can be built for under US$200. They are encouraging people to build similar billboards in other areas of Brazil, as the majority of babies affected by Zika are located outside Rio.
