Rain transforms dissolving poster into a deadly mosquito trap

In tropical countries like Brazil the accumulation of standing water helps fuel the breeding of  mosquitos which transmit the Dengue and Zika viruses and other diseases.

To raise awareness Habitat for Humanity Brazil, created special posters that dissolve in the rain and kill the mosquito before they hatch.

The dissolving poster responds to water and releases environmentally friendly insecticide that lasts up to 60 days.

This initiative was born from a powerful larvicide it was added to a soluble rice sheet and organic glue.

On sunny days, the posters carry educational messages that teach people how to avoid standing water.

And, when it rains, the sheets dissolve, going with the water flow, releasing the larvicide in its composition and eliminating the mosquito larvae on its path.

With just one poster it is possible to exterminate the Aedes Aegypti larvae in up to 200 liters of water for at least 60 days.

“It is very difficult to make people be aware of the issue, even when it comes to garbage, rubbish and domestic waste. It’s all there, with that rotten water standing on the streets” says Dona Dilza, a resident of the Heliopolis community, located in the south of São Paulo. “The project comes in an innovative way. It educates, prevents and kills the mosquito where people do not reach” adds Denis Pacheco, Habitat Program Coordinator.

Through this creative campaign, Habitat for Humanity manages to help curb mosquito-borne viruses while also raising awareness about its work
