Prevent bug bites Bugs (like mosquitoes, ticks, and fleas) can spread a number of diseases in Barbados. Many of these diseases cannot be prevented with a vaccine or medicine.

While Barbados is generally safe from large dangerous predators, there are several smaller creatures that can give you a nasty bite or sting. The most significant concern for many is the giant centipede, which can grow up to 10 inches long and delivers a painful, venomous bite that causes swelling and intense throbbing; while rarely fatal, it often requires medical attention for pain management. On the beaches, sand flies (often called "no-see-ums") are common and can leave itchy, persistent red welts, while mosquitos are present and carry a risk of Dengue fever. In the water, you should watch out for sea urchins and the Portuguese Man o' War, which can deliver a severe sting. Interestingly, Barbados is one of the few Caribbean islands that is almost entirely free of venomous snakes, as the invasive mongoose was introduced in the 1800s and effectively wiped out most of the local snake population. If you encounter a Green Monkey, be cautious as they can bite if they feel cornered or if you try to feed them, though they are usually shy.
