As cases of mosquito-transmitted illnesses climb across the Caribbean region, public health organizations have launched a regional campaign urging residents to tackle mosquito breeding sites starting at home, warning that unaddressed standing water in residential backyards has become a key contributor to the growing public health threat.
From May 11 to 15, 2026, the Caribbean Public Health Agency (CARPHA), in partnership with the Caribbean Community (CARICOM) and the Pan American Health Organization (PAHO), is hosting Caribbean Mosquito Awareness Week. This year’s initiative carries the central theme: “Stop Disease Transmission, Start Source Reduction,” shifting focus from information sharing to collective community action.
Dr. Lisa Indar, Executive Director of CARPHA, emphasized that individual and community action is the foundation of effective mosquito control. “This observance is not just about sharing information; it is about encouraging action. It is about reminding each Caribbean citizen that mosquito control starts at home, in our schools, in our workplaces and in our communities,” Indar explained in her opening remarks for the campaign.
Public health officials are sounding the alarm over accelerating disease spread across the region. Once-controlled illnesses including dengue, malaria, yellow fever and chikungunya are seeing consistent increases in case counts. CARPHA has specifically flagged the reemergence of yellow fever and chikungunya in South America, noting that the viruses are spreading quickly and pose an immediate cross-border risk to the entire Caribbean basin.
Experts point to multiple interconnected factors driving the current surge, many of which originate in residential spaces. Stagnant water that accumulates in common backyard items, combined with inadequate regional waste management and shifting climate patterns that extend mosquito breeding seasons, have created near-perfect conditions for mosquito populations to explode in communities across the Caribbean. Standing water that collects in unmaintained containers, clogged gutters, and outdoor gardening supplies is one of the most common unaddressed breeding sites that allow mosquito populations to grow rapidly close to where people live and gather.
The campaign provides clear, actionable steps that every resident can take to reduce local mosquito populations and protect their households. Key recommendations include sealing all water storage drums and barrels, emptying or disposing of any outdoor containers that can catch rainwater, clearing debris from gutters on a regular schedule, and scrubbing vases and flower pot saucers weekly to remove mosquito eggs. Residents are also advised to use registered insect repellent and wear long, protective clothing when spending time outdoors, and to seek immediate medical care if they develop symptoms of illness after a mosquito bite.
Indar closed by reinforcing the core message of the week: small, consistent actions taken by individual households add up to large regional change. “Keep mosquitoes away; clean up today,” she urged, noting that collective commitment to source reduction is the most effective way to slow disease transmission and protect Caribbean communities.
