The municipal government of João Pessoa has begun implementing Larvicide Disseminating Stations (EDL) to combat the Aedes aegypti mosquito, which transmits dengue, zika, and chikungunya. The technology uses surfaces impregnated with larvicide that mosquitoes pick up on their bodies and transport to various breeding sites, such as gutters and water tanks.

Following the initial installation of a station at an industrial scrapyard in the Novais neighborhood, the city expanded the rollout to the Jardim Veneza neighborhood. This initiative is part of a larger mosquito control strategy supported by the Ministry of Health, which is providing more than 800 EDLs to the municipality. Current monitoring efforts also include the use of 625 ovitraps to track mosquito egg-laying patterns across the city.

In response to concerns that rising temperatures and rainfall patterns associated with El Niño are creating ideal conditions for vector proliferation, the Municipal Health Secretariat has intensified its efforts. Beyond technological interventions, officials are implementing integrated monitoring and control measures, including health education programs for students from preschool through high school in both public and private networks to encourage early prevention habits.
