Mosquitos Found in Cayman

There are 18 different types of mosquitoes in the Cayman Islands.

To help control them, we have special traps placed in key locations across the islands. These traps are checked every day.

By looking at the number of mosquitoes caught in each trap, we can tell if the mosquito population in an area is higher than normal. This helps us decide where and when to take action to keep mosquito numbers low.

For mosquitoes that breed around homes, our teams inspect properties and record their findings in our database. This information also helps guide our control efforts and allows us to focus on the areas that need the most attention.

Daily monitoring is one of the most important tools we use to protect our communities and reduce the risk of mosquito-borne diseases.
