The Mosquito Research and Control Unit (MRCU) has begun island-wide aerial larviciding across Grand Cayman.
The operation will begin in West Bay and progressively move east across the island. It is expected to take approximately one week to complete, weather permitting. Following the completion of aerial larviciding in Grand Cayman, MRCU will then carry out treatment operations in the Sister Islands.
During the operation, residents will see MRCU’s aircraft flying at low altitude during the daytime and making multiple passes over treatment areas. These repeated passes are necessary to ensure effective and thorough coverage of mosquito breeding areas.
MRCU understands that seeing an aircraft flying at a low altitude can sometimes cause concern. MRCU pilots are specially trained to carry out this type of work, and operating at a low altitude is necessary to ensure the larvicide is accurately applied to the areas being treated.
The product being used for this operation is Natular G30, a granular larvicide used to target mosquito larvae before they develop into biting adults.
Information on Natular G30 and all other products used by MRCU, including product labels and Safety Data Sheets, is available on the MRCU website at: https://gov.ky/web/mrcu/products.
Recent rainfall has also created additional opportunities for mosquitoes to breed around homes and properties. MRCU encourages residents to walk around their property at least once a week and empty, turn over or dispose of anything holding water. Even small amounts of standing water can provide a place for mosquitoes to breed.
Weather conditions, including rain and wind, may affect the progress of the aerial operation.
MRCU’s mosquito control work supports the Cayman Islands Government’s Broad Outcome for Health and Social Development, which aims to achieve “Healthy and Empowered People with Improved Quality of Life for All Ages.” Through ongoing mosquito surveillance, prevention and control, MRCU works to protect public health and support the wellbeing and quality of life of residents and visitors.
MRCU thanks the public for its cooperation and understanding as teams continue working to reduce mosquito populations across Grand Cayman.
