Cayman ramps up mosquito control with daytime aerial larviciding

With Cayman’s rainy season underway, the Mosquito Research and Control Unit is intensifying efforts, conducting island-wide daytime aerial larviciding to kill mosquito larvae before they become biting adults, alongside surveillance and biological controls. Scientists identify 36 species on the islands, notably Aedes aegypti, which spreads dengue, Zika and chikungunya. Mosquito bites are more likely in people with higher body heat and carbon dioxide output, skin bacteria, or sweat chemistry, and ankles, wrists, and neck are common bite sites. Residents are urged to remove standing water and support integrated pest management, including Gambusia fish, to curb emergences.
