Grand Cayman, Tuesday, 21 March 2023 – The Mosquito Research and Control Unit (MRCU) would like to advise the public in relation to a significant mosquito emergence expected from Sunday evening, 26 March 2023, onwards. 

Dr Alan Wheeler, Director of the MRCU, explains: “High tides combined with unseasonal rainfall have resulted in widespread flooding across Grand Cayman, and MRCU surveillance has identified high numbers of mosquito larvae developing in these flooded areas.”

While the MRCU conducted a wide-scale residual larviciding treatment before the rainfall, it still expects a mosquito problem due to the extent of the flooding.   “We expect the mosquito numbers to remain high for most of next week while we work to control the problem,” Dr Wheeler adds. “Residents are advised to avoid early evening outdoor activities while we work to bring the problem under control.”
