In tropical countries like Brazil, it rains all year round. That means lots of standing water and breeding sites for the Aedes aegypti mosquito, the transmitter of many fatal diseases, such as Zika, Dengue, Chikungunya and Yellow Fever. Especially in the poorest regions and difficult areas to approach, like the favelas.
Habitat, a NGO that helps millions of families around the world to live in more suitable homes, decided to reach those places and do something about those outbreaks.
So, instead of a simple awareness campaign, we created special posters that dissolve in the rain, releasing a powerful larvicide that kill the mosquitoes before they hatch.
We used the Bacillus thuringiensis serotype israelensis(BTI) in the composition of the posters, mixed with a organic glue, biodegradable ink and large sheets of rice paper. This way, the posters are safe to animals, the environment and people.
One single poster protects 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.
