On World Mosquito Day, MRCU highlights data-driven success in controlling Cayman’s mosquito population

Community involvement is crucial in strengthening mosquito control efforts and protecting public health
GRAND CAYMAN, Cayman Islands (19 Aug. 2024) – As we observe World Mosquito Day on 20 August, the Mosquito Research and Control Unit (MRCU) highlights the relentless efforts that have gone into keeping mosquito numbers low this year, ensuring the safety and comfort of the Cayman Islands’ residents and visitors.


“Mosquito control is a science-driven process that requires constant vigilance and adaptive strategies,” said Dr Alan Wheeler, PhD, Director of MRCU. “Our team works tirelessly behind the scenes, collecting and analysing larvae from communities, swamps and dykes, and carrying out property inspections. Daily, we count and identify mosquitoes from traps, and our morning meetings are essential for planning our day’s mission based on the latest data and community feedback.”


One key aspect of MRCU’s work is the absence of a fixed spray schedule. “Everything we do is data-driven,” explained Dr Wheeler. “We base our actions on real-time observations and analysis to ensure the most effective and efficient mosquito control measures. This approach allows us to target problem areas precisely when and where interventions are needed.”


The Cayman Islands are home to about 20 different types of mosquitoes. While some prefer birds or other animals, others, like the Aedes aegypti mosquito, pose a risk to human health. “The Aedes aegypti is particularly concerning because it’s a day-biting mosquito that breeds in people’s yards,” Dr Wheeler said. “This mosquito is the primary vector for serious diseases such as dengue, Zika and yellow fever. With dengue cases rising in the region, our disease prevention officers have been proactively visiting homes, dumping water out of any container that might serve as a breeding ground.”


The MRCU stresses that controlling the Aedes aegypti mosquito requires a community-wide effort. “It’s not something we can do alone,” said Kevin Watler, Public Education and Outreach Officer. “We urge every resident to inspect their property weekly for any containers that can hold water, no matter how small. Even a bottle cap can become a breeding site. If you’re bitten by an Aedes aegypti, there’s a good chance it was born right in your yard or your neighbour’s yard.”


As the new school year approaches, MRCU has intensified its efforts with mosquito barrier treatments to protect students and staff as they return to school. “These treatments create a protective barrier around properties, reducing mosquito populations in the treated area,” Watler added.


Residents are also encouraged to play an active role in mosquito control by reporting any mosquito problems in their area. “By emailing [email protected]<mailto:[email protected]> with details such as the time and location of mosquito activity, the community can help us gather vital data to carry out the appropriate treatments, use chemicals efficiently, and effectively reduce or eliminate mosquito bites,” said Watler.


MRCU regularly shares updates on its activities on Facebook<https://www.facebook.com/MRCU.Cayman/> and LinkedIn<https://www.linkedin.com/company/cayman-islands-mosquito-research-and-control-unit>, keeping the public informed about ongoing efforts to control mosquito populations.
The MRCU remains committed to protecting the Cayman Islands from mosquito-borne diseases and maintaining the quality of life for all residents. This World Mosquito Day, we ask everyone to join us in our mission by staying vigilant and proactive in mosquito control efforts.
