Minister Joins MRCU for Field Surveillance

It was boots-on-the-ground for the Minister of Health, Environment and Sustainability, Hon. Katherine Ebanks-Wilks, as she joined the Mosquito Research and Control Unit (MRCU) in the field to see just what it takes to tackle Cayman’s most persistent pest.

The Minister was up bright and early, arriving at MRCU headquarters at 7:00 a.m. on 16 June, to take part in the team’s daily morning briefing. From there, she headed out with Disease Prevention Officers John Berry and Garbeth Wright to explore some of the more challenging areas where mosquito control happens—swampy terrain, residential backyards, and the rugged dykes that crisscross the landscape.

“It’s been a real eye-opener,” said Minister Ebanks-Wilks. “Walking through the dykes, in areas where the terrain isn’t exactly safe, and being swarmed by mosquitoes—this experience gave me a better understanding of the tough conditions our officers face every day. And I was genuinely surprised to see just how little water it takes for mosquito larvae to appear. It really shows why public support is so important.”

During the visit, the Minister observed how MRCU officers inspect standing water, apply larvicides, and assess potential breeding sites, often in locations where even vehicles struggle to pass. She expressed her appreciation for the team’s dedication and pledged to advocate for safer working conditions where needed.

“These officers work tirelessly, and they do it quietly—often in areas the public doesn’t see,” she added. “The more we can do at home—turning over containers, checking for stagnant water—the more we help them. Everyone is feeling the mosquitoes this time of year, but MRCU is out there daily with the trucks, testing and treating. It’s a small team doing a massive job.”

MRCU Director Dr. Alan Wheeler said the visit was a great opportunity to showcase the breadth of work that goes into mosquito control—much of which takes place well before any fogging truck rolls out or the aircraft takes to the skies.

“Mosquito control in Cayman is a science-led operation,” said Dr. Wheeler. “We’re in the field collecting data, inspecting breeding sites, and applying treatments in a targeted way that protects both public health and the environment. It’s more than just fogging—it’s about long-term, strategic control.”

The MRCU encourages residents to do their part by regularly checking around their homes for standing water. Just a bottle cap’s worth is enough to breed mosquitoes, and small actions can make a big difference.
