Brazil’s New Zika Strategy: Billboards Smell Like Humans to Attract and Kill Mosquitoes

Mosquito Killing Billboard

This billboard may remind us of a giant fly swatter, and it actually kills mosquitoes that carry the Zika virus —by smelling like humans.

The signs are going up around Brazil in an effort to wipe out the bugs and their virus, which is linked to birth defects in newborns and nervous system disorders in adults.

The billboards emit a lactic acid and carbon dioxide (CO2) solution that smells to mosquitoes like human sweat or an exhaled breath. Lights added at night keep attracting the biting bugs with the promise of warmth.

Mosquitoes that are within a one-and-a-half mile radius can be lured into traps at the base, then live out their natural lives inside the sign, unable to bite anyone.

The billboards were designed under a Creative Commons license, meaning they can’t be patented and their plans are available for other cities and countries to duplicate and build free of charge.

This isn’t the first time a billboard has wowed us with brilliant innovation to help solve human problems. The University of Engineering and Technology of Peru has wowed us again. Their first billboard to get worldwide attention provides drinking water to a parched and arid region of Peru. Another creation, built on  a construction site with massive amounts of swirling dirt, is actually cleaning the air for workers and neighbors alike .
