Cayman: Mosquito populations have rebounded since August

The ongoing rainfall in Cayman is supporting the production of mosquitoes island-wide. Minister of Health, Hon. Dwayne Seymour updated the population on the activities of the Mosquito Research and Control Unit at the government press briefing last week.

In August, populations of biting mosquitos were low. Aerial larviciding and wide scale larviciding with truck mounted equipment took place the third and fourth weeks of August. 

According to the Minister of health, populations have rebounded in the past two weeks.

Both planes from the Mosquito Research and Control Unit (MRCU) have been flying to combat the situation, nearly continuously and all fog trucks have been actively spraying as well. Planes are expected to fly every night moving forward, weather permitting.

Surveillance of swamps is on-going and surveillance and treatment of rain water and container mosquitoes around residences is on-going.

As of last week, mosquito breeding was found in several locations on the West Bay Peninsula and aerial larviciding operations will commence to control these mosquitoes before they emerge as biting adult mosquitoes.

The community is reminded that when possible, any outdoor container holding water is a potential mosquito breeding site. Tip containers to remove water, toss unused containers in the trash, cover containers when possible or flush the water in containers on a weekly basis.
