Which people do mosquitoes prefer to bite? Here are six reasons why some become mosquito targets.

Many have experienced sitting together but only one person is swarmed by mosquitoes, raising the question, "Which people do mosquitoes prefer to bite?" Experts in entomology and public health agencies say mosquitoes don’t choose victims based on "sweetness" of blood as commonly thought, but several biological factors attract them, as follows.

1. People who emit high levels of carbon dioxide.

Mosquitoes can detect carbon dioxide from breathing up to 30 meters away. Therefore, people who have just exercised or larger individuals who breathe heavily are more likely to be bitten.

2. People who sweat a lot and have body odor.

Lactic acid and ammonia released through sweat are scents that mosquitoes favor.

3. Higher body temperature.

Mosquitoes prefer people with warmer bodies than usual, such as pregnant women or those with mild fever.

4. Blood type.

Studies show mosquitoes (especially Aedes mosquitoes) prefer to bite people with blood type O twice as much as other blood types.

5. Wearing dark-colored clothing.

Mosquitoes see objects with colors that contrast with the environment clearly, especially black, dark blue, or red.

6. Skin bacteria.

The amount and type of natural skin bacteria influence mosquitoes to select certain individuals to bite.

Basic treatment for "mosquito bite allergies" to reduce swelling and itching.

For people who are allergic to mosquito bites, the symptoms are often more severe than usual, such as large, hard red bumps or blisters. Proper care helps reduce the chance of scarring.

Wash with soap and water immediately.

Once bitten, wash the area with clean water and mild soap to remove any mosquito saliva residue on the skin.

Apply cold compress.

Use cold to reduce swelling and temporarily relieve itching.

Use appropriate topical medication.

  • If itching is severe, use calamine lotion or topical antihistamines.
  • If swelling and redness are intense, mild corticosteroid creams may be needed as advised by a pharmacist.

Avoid scratching.

Scratching can cause skin inflammation and increase risk of bacterial infection, which is the main cause of dark marks after mosquito bites.

How to prevent becoming a mosquito’s target.

Besides knowing which people mosquitoes prefer to bite, prevention is the best solution.

  • Choose light-colored, covering clothing when going to mosquito-prone areas.
  • Use approved mosquito repellents such as DEET or citronella oil.
  • Eliminate standing water around the home to break the mosquito breeding cycle.
