What We Do

Our Purpose: Protecting Today, Safeguarding Tomorrow.

The Mosquito Research & Control Unit (MRCU) is dedicated to protecting the health and well-being of the Cayman Islands by reducing mosquito populations and preventing the spread of mosquito-borne diseases.

Through our research, public outreach, and sharing of resources, MRCU is committed to being a trusted source of knowledge and support. We strive to empower residents with the information and tools they need to create a safer, healthier community.
