Yes, mosquitoes exist in Punta Cana, especially during the rainy season. Their presence, however, poses a minor threat if you're well-prepared and take necessary precautions. Most tourist areas have strict control measures, including daily cleaning and fumigation routines, to keep these minor nuisances to a minimum.

In 2026, mosquitoes remain a significant presence in the Dominican Republic, particularly during the wet season from May to November. While they are a nuisance, the primary concern is the transmission of mosquito-borne illnesses such as Dengue, Zika, and Malaria. Recent 2025-2026 data shows a 17% reduction in malaria cases, but provinces like Azua and San Juan are still considered higher-risk areas. Tourists are strongly advised to use insect repellent containing DEET, wear long sleeves during dawn and dusk, and ensure their accommodations have proper window screens or air conditioning. While major resort areas like Punta Cana conduct regular "fogging" to control the population, travelers venturing into rural or tropical zones should be diligent with protection to avoid both the itchy bites and the health risks associated with local tropical viruses.
