Why do mosquitoes bite me more than others? Because mosquitoes choose their target by smell and heat, not by chance. Some people give off more carbon dioxide and sweat and skin odours that attract mosquitoes, so they get bitten first. Only female mosquitoes bite, because they need blood to produce eggs.

What makes mosquitoes choose you?

  • Breath: carbon dioxide is the first signal mosquitoes follow from a distance; the more you breathe (after exercise or in larger bodies), the clearer a target you are.
  • Body heat: mosquitoes sense heat, so a warmer person attracts them more.
  • Sweat and skin odour: compounds such as lactic acid and natural skin bacteria give each person a different smell, and mosquitoes prefer some smells over others.
  • Dark clothing: mosquitoes see dark colours more easily, especially black and navy.
  • Pregnancy: pregnant women breathe out more and are warmer, so they get bitten more.

Why do bites itch more for some people?

  • The mosquito injects saliva into the skin, and the body reacts to it.
  • Some people have a stronger reaction, so their bites are bigger, redder and itchier.
  • Two people may get bitten the same number of times, but one feels it and the other does not.

How to stop mosquitoes biting you

  1. Run a fan near you while sleeping, as mosquitoes are weak fliers and cannot reach you in the airflow.
  2. Wear light, long clothing at dusk and at night.
  3. Use a skin mosquito repellent from the pharmacy on exposed areas.
  4. Fit window screens, or sleep under a mosquito net.
  5. Remove standing water at home, as it is where mosquitoes breed.
  6. Spray a residual insecticide on the walls where mosquitoes rest inside rooms.

Mosquito bite FAQs

Do mosquitoes prefer a certain blood type?

Some studies noticed mosquitoes lean towards type O, but this is not settled, and smell and breath matter far more than blood type.

Why do mosquitoes buzz around the ear?

Because breath comes from the face and head, so mosquitoes follow it and hover there, and you hear their wings near your ear.

Are there people mosquitoes never bite?

Hardly. Anyone can be bitten, but some people get bitten less or do not notice the bite.
