Dissolving Posters


In tropical countries like Brazil, it rains all year round, increasing the accumulation of standing water and the outbreaks of the Aedes aegypti mosquito, which transmits the Dengue, Zika and Chikungunya viruses, and other diseases – mainly in favelas and difficult access areas. To reach those places raising awareness and fighting against the insects, we created special posters that dissolve in the rain and kill the mosquito before they hatch.

In addition to informing the population about the danger of standing water accumulation, the only way to combat the mosquito is to eliminate its larvae in its breeding sites. This initiative was born from a powerful larvicide, the BTI (Bacillus Thuringiensis Israelensis), developed by one of the most prominent health science and technology institutes in Latin America. We used the BTI mixed with an organic glue, biodegradable ink and large sheets of rice paper – for the composition of the posters. This way, the posters are safe to animals, the environment and people.

With just one poster it is possible to exterminate the Aedes Aegypti focus in up to 200 liters of water and lasts up to 60 days.

But what if it doesn’t rain? The poster, in dry conditions, can still be effective for up to 2 years. All is needed to activate the BTI is just a little bit of water. And, during dry weather, the poster have messages of awareness and tips to help residents to avoid the mosquitos.
