The most common mosquito species prefer to feed at dawn and dusk and will continue feeding two to three hours after dark. Try to avoid going outside as much as possible during these times. Be aware, however, that some species feed during the day and are aggressive biters.
Wearing light, loose clothing
One way mosquitoes select prey is by homing in on the heat produced by warm-blooded bodies. Dark-colored clothing traps heat, making the wearer the warmest prey for the mosquito. Mosquitoes also have photosensitive eyes that can detect bright colors. And, looser clothing makes it more difficult for the mosquito to penetrate the skin.
Avoid scented bath products
Although the reasons aren’t clear, mosquitoes seem to be attracted to fragrances used in shampoos, colognes, perfumes and lotions. Not every product or scent will attract them, but many do, so it is best to leave them off when spending time outdoors.
Sprays that mask the skin odors most attractive to mosquitoes make it possible for people to hide in plain sight. A repellent containing DEET or another proven chemical blinds the receptors mosquitoes use to pick up on skin odors, meaning they aren’t able to locate their prey. Apply it lightly to exposed skin, avoiding cuts and sores.
Use Mosquito Nets and Screens
Fit mesh screens on hatches, portlight and companionway to provide mosquito-free zones inside your boat. Mosquito netting has fine holes that are big enough to allow breezes to easily pass through, but small enough to keep mosquitoes and other biting insects out.
