Unique sign that makes you 'sweat' trying to trap mosquitoes carrying Zika.

A sign in Brazil that "sweats" is being touted as a brilliant idea to combat the Zika virus, as it can trap and kill mosquitoes carrying this dangerous virus.

A device inside the panel will emit lactic acid—a component found in sweat—and carbon dioxide, similar to human breath, to "attract" mosquitoes.

At night, the mosquito-killing board is also equipped with fluorescent lights to attract prey. Mosquitoes get trapped in the board and then die from dehydration.

The mosquito control sign is placed at a height of 1.2 meters to match the flight range of these insects. This sign can attract insects from a distance of about 2.4 kilometers.

The inventors of the mosquito-killing signs – two advertising companies, NBS and Posterscope – did not register any intellectual property rights; in fact, they released the design of the mosquito-killing signs for free, thus encouraging other countries to manufacture these devices.

A representative from Posterscope told the BBC that each sign costs around several thousand real to produce (1,000 real is equivalent to 412 USD).

The Zika virus, transmitted primarily through the bite of Aedes mosquitoes, is currently the leading suspect in microcephaly in children. To date, there is no vaccine or specific treatment for the Zika virus. The virus has now appeared in over 43 countries, including Brazil.

As the 2016 Olympics drew closer, Brazil, as the host nation, implemented numerous mosquito control measures around Rio de Janeiro to ensure the safety of the thousands of tourists expected to arrive. Two mosquito control signs were installed on the streets of Rio de Janeiro.

Chris Jackson, an insect control expert at the University of Southampton, believes that the mosquito-killing signs are a good initiative but could potentially attract mosquitoes to urban areas.
