Mosquitoes Choose Who They Bite: Fact

Mosquitoes are quite pesky and bite their fair share of people, but do they choose their victims? Let’s find out in this month’s fact or fake.

When mosquitoes are on the prowl looking for their next meal, they don’t just target the closest person. Mosquitoes are very discerning when it comes to who they bite, and several factors play into this. From blood type and body weight to sweat and carbon dioxide levels, mosquitoes take these features into account before they decide to strike. Since mosquitoes can spread many diseases including West Nile virus, malaria, and Zika, take these factors into account before embarking on your spring outdoor festivities.

  • Clothing and Heat – Mosquitoes target victims with their eyes, so wearing dark clothing (black, red, etc.) can make you easier to locate.
  • Blood Type and Sweat – Mosquitoes can smell what blood type people are by compounds and secretions emitted in sweat.
  • Weight and Gas – A person’s size is also considered by the mosquito. Because larger sized people have greater body heat, a more evident target to bite and expel added carbon dioxide when they breathe (which mosquitoes can smell), they are of prime interest to the mosquito. These same traits also make pregnant women more likely to be targeted by biting mosquitoes.
