Overview

• Mosquitoes rely on visual, thermal and especially chemical cues emitted by humans rather than selecting targets at random.
• High levels of exhaled carbon dioxide make individuals—such as pregnant, taller or heavier people—more attractive to mosquitoes.
• Elevated body temperature after exercise and odors produced by skin bacteria further increase a person’s appeal.
• Studies indicate mosquitoes prefer blood type O and respond strongly to sweet perfumes resembling fruit or dessert scents.
• To reduce bites, experts recommend regular repellent application, choosing scent-free products and wearing long clothing during dawn and dusk.
