Mosquito Vs Mosquito is the result of a partnership between QuintoAndar - the largest digital real estate company in Latin America - and Oxitec - a global leader in biotechnology - aimed at addressing a significant public health challenge through innovation: dengue fever. By using genetically modified mosquitoes, we have transformed thousands of our homes into points of protection against dengue, creating the largest mosquito network protection in Latin America. This innovation reinforces the brand's commitment to improving lives and promotes a tangible impact on millions of families.

Brazil had one of the highest dengue fever incidences globally with 2.5M cases in 2 years, according to the World Health Organization. A disease transmitted by the female Aedes aegypti mosquito, that breeds in urban areas laying its eggs in places with standing water. QuintoAndar - the largest digital real estate company in Latin America with over 100,000 houses in its portfolio - has as its brand role to help people live better. So our goal was to leverage the reach of our real estate network to fight dengue fever in Brazil in an innovative way.

As 80% of mosquitoes are born in home's backyards, gardens and sheds, QuintoAndar - the largest digital real estate company in Latin America - teamed up with Oxitec - a global leader in biotech - to fight dengue at its source: people's homes. We used genetically modified mosquitoes engineered by Oxitec to transform our houses into dengue protection points. These mosquitoes are male developed to eliminate their own species. When they mate with females - the ones that bite and transmit the disease - generate only harmless male offspring like themselves, reducing the female mosquito population and consequently, the cases of dengue.

Mosquito Vs Mosquito boxes - containing the mosquitoes' eggs - were given to tenants in the neighborhood with the highest dengue cases. Then, we made the boxes available on our website, creating the largest dengue prevention network in the country and impacting the lives of millions of families.

Genetically modified mosquitoes are an innovative, simple, safe, and sustainable biological solution to help combat the Aedes aegypti mosquito, the transmitter of dengue fever.

The mosquitoes are male and have been engineered to eliminate their own species. When they mate with females - the ones that bite and transmit the disease - they only produce harmless male offspring like themselves, thereby reducing the female mosquito population and, consequently, the cases of dengue.

The mosquito eggs are stored inside the Mosquito Vs Mosquito box, which contains water-preserving sachets and a food source for the mosquitoes to develop into adulthood. To activate the box, simply add water. In about 14 days, the mosquitoes emerge and fly into the urban environment in search of females to mate with.

This technology was developed by Oxitec - a global leader in biotechnology - and thanks to the partnership with QuintoAndar, it is the first time it has been applied on a large scale within people's homes, ushering in a new phase in the fight against Aedes aegypti.

Mosquito Vs Mosquito has been a game-changer in the fight against dengue in Brazil, achieving a 96% success rate in controlling the spread of Aedes aegypti in treated areas.

Within hours of launching, the results were remarkable, with 60,000 accesses to the landing page, 75% of which were organic. Orders for Mosquito Vs Mosquito boxes sold out quickly, creating a waiting queue on day one.

The response on social media was overwhelmingly positive, with 88% favorable comments, (+18 pp vs brand's average). In less than a month, the campaign reached over 29.4 million people, helping spread awareness on an important cause.

The distribution of thousands of boxes has helped protect about 10 million people in an area equivalent to over 2,600 soccer fields. Thanks to influencers and the hashtag #housesagainstaedes, organic social impressions increased to 1.7 million.

According to data from the Brazilian Ministry of Health, surprisingly, about 80% of dengue mosquitoes are born inside households. They breed in containers with stagnant water, such as plant pots, old tires and bottles. The project Mosquito Vs Mosquito, by QuintoAndar, uses genetically modified mosquitoes as an innovative strategy to combat dengue, highlighting the community concern and social responsibility of the brand. By engaging thousands of families in dengue prevention efforts, the initiative was widely perceived as an impactful and effective action in the fight against the disease.
