MRCU Aerial Operations Begin

Please be advised that the Mosquito Research & Control Unit (MRCU) will be conducting aerial operations over mosquito-breeding swamp areas on Grand Cayman from today (Thursday, 20 November 2014).

These operations will involve low-level flights during the mornings and late afternoon. The operation will start in the area of West Bay and finish on the north side of the island. Weather permitting; the full application should be complete within ten days.

The distinctive red and white MRCU aircraft will be applying the small pellets specifically designed to target mosquito larvae developing in aquatic habitats; this means preventing the occurrence of biting mosquitoes. Once the rains begin, the pellets are activated and will provide control for up to two months. Low-level flights over specific areas are necessary to ensure that correct application and successful control of mosquitoes is achieved.

This is the third island-wide treatment this year, on Grand Cayman, and the Sister Islands. This will assist in providing control through the Christmas period to January next year. Some 12,000 acres of swamp are targeted in this operation in Grand Cayman, 320 acres in Cayman Brac and 475 acres in Little Cayman. Due to elevated mosquito breeding in Little Cayman, the aerial application in the Sister Islands was completed several weeks ago which is slightly earlier than usual.

Further information and daily schedules can be found on the Mosquito Research & Control Unitís Facebook page or website A daily update of the areas being treated will also be available on those sites.

Please feel free to call MRCU with any enquiries on 949-2557.
