How This ‘Sweaty Billboard’ is Fighting The Zika Virus

There’s no solution to solving the zika virus epidemic right now, but there’re people working on it.

Take this innovative approach: Brazilian marketing agencies have created a billboard that attracts and kills mosquitoes, who’re the carriers of the debilitating disease.

The ad boards release a mixture of a lactic acid solution that mimics the smell of human sweat and carbon dioxide, aka human breath. The board is effective on the bloodsuckers up to 2.5 km away. Not only are they plopping them all over the country, the agencies have released the blueprint of their creation, encouraging others to start putting up these billboards.

A downside to this ‘solution’ is it’ll attract mosquitoes to denser areas of people, say some experts.

The mosquitoes are trapped behind the glass barrier, along with the message of the board’s purpose. Two of the Mosquito Killer Billboards have already been put up in Brazil’s capital, Rio de Janeiro.

The agencies have no intent of selling ad space in these billboards.

“It’s impressive how many mosquitoes you can trap and how many lives you can save with this idea,” Otto Frossard from Posterscope, one of the agencies, told the BBC.

“I think anything that can be done to reduce the prevalence of the mosquito is a good thing,” added Dr. Chris Jackson, a pest control expert at the University of Southampton.

“Particularly devices like this that attract and kill females that feed on blood, as it is only female mosquitoes that bite.”

The only issue, as mentioned earlier, is the boards not only attract a crowd of mosquitoes, but humans as well.

“Maybe if it was not in a high-density place, where people are sitting perhaps with exposed legs… otherwise, you’re pulling in hungry mosquitoes and providing them with exposed human flesh,” said Jackson.
