Mosquito Basics

Mosquitoes (Order Diptera, Family Culicidae) are among the most adaptable and resilient insects, capable of thriving in diverse and often extreme environments. Nearly any natural or artificial body of water can support mosquito breeding. These insects have been found in locations as deep as mines, nearly a mile below the earth's surface, and on mountain peaks over 14,000 feet high. If there’s standing water, there’s a good chance that mosquitoes may be breeding nearby—even in your own backyard.

 

Not all mosquito species are harmful to people, but many have significant negative impacts on health and quality of life. Mosquitoes can be recognized by their long, piercing proboscis and the unique scales on their wing veins. In the Cayman Islands, around 35 mosquito species are present, though only a few carry diseases that affect humans. However, many more species are considered nuisance mosquitoes, which can severely disrupt daily life.

Mosquito-borne illnesses are infectious diseases transmitted to humans and animals through the bites of infected mosquitoes. These illnesses—including malaria, dengue fever, Zika virus, chikungunya, and West Nile virus—pose serious public health risks, especially in tropical and subtropical regions where mosquitoes thrive. Preventing and controlling mosquito populations are critical in reducing the spread of these diseases and protecting the health of residents and visitors alike.
