GRAND CAYMAN, Cayman Islands (20 October 2026) – The Mosquito Research and Control Unit (MRCU) confirms that its aircraft has successfully completed its mandatory 100-hour inspection and is once again available for mosquito control operations across the Cayman Islands.
The return of the aircraft restores an important part of MRCU's mosquito control capabilities, allowing the Unit to carry out aerial treatments alongside its ongoing truck fogging, larviciding and ground-based control activities.
Mosquito numbers have improved considerably compared with two weeks ago, an encouraging indication that control efforts are making progress. However, MRCU recognises that mosquito activity remains at unacceptable levels in several communities, and some residents continue to experience significant biting.
The Unit continues to monitor mosquito populations through surveillance traps, field inspections and reports from residents to help identify areas requiring additional attention.
MRCU encourages residents who continue to experience high mosquito activity to report their concerns by emailing MRCU@gov.ky or sending a WhatsApp message to 936-8503. Residents are encouraged to include their location and details of the mosquito activity they are experiencing. This information helps MRCU identify problem areas and supports operational planning.
Residents also have an important role to play in reducing mosquito breeding around their homes. MRCU encourages everyone to walk around their yard or property once or twice each week, checking carefully for anything that may have collected water.
Even the smallest amount of standing water can provide a breeding site for certain mosquito species. Buckets, plant saucers, discarded tyres, children's toys, bottles and other containers should be emptied regularly. Items that are not being used should be stored under cover or turned upside down to prevent rainwater from collecting.
While much of the recent mosquito activity has been associated with flooding in wetland areas, eliminating standing water around homes helps prevent additional mosquito breeding within residential communities.
MRCU will continue its mosquito control efforts across the Cayman Islands, using surveillance data and field assessments to guide operations. Residents are encouraged to follow MRCU's social media pages and WhatsApp Channel for updates on mosquito control activities in their areas.
