Mosquitoes Do Not Choose Their Victims Randomly

Various factors make certain people more attractive to these insects. Below are the main reasons supported by recent research:

1. Carbon Dioxide (CO₂) Emission

People who exhale larger amounts of CO₂, such as adults or individuals with higher body mass, attract mosquitoes more. These insects can detect CO₂ from up to 30 meters away.

2. Presence of Lactic Acid and Other Compounds on the Skin

Substances like lactic acid, uric acid, and ammonia, present in sweat, are highly attractive to mosquitoes. The buildup of these substances, especially after physical exercise, increases the likelihood of being bitten.

3. Alcohol Consumption

Drinking alcoholic beverages, such as beer, can make a person more attractive to mosquitoes. This is due to changes in body chemistry and the release of volatile compounds through sweat.

4. Pregnancy

Pregnant women exhale more CO₂ and tend to have a higher body temperature, factors that increase their attractiveness to mosquitoes.

5. Skin Microbiota

The composition and quantity of bacteria on the skin influence body odor, making some individuals more appealing to mosquitoes. Interestingly, greater bacterial diversity can act as a natural repellent.

6. Clothing Color

Mosquitoes use visual cues to locate their hosts. Wearing dark or bright-colored clothing, such as black, blue, or red, can increase visibility and, consequently, mosquito attraction.

Preventive Measures

To reduce the risk of mosquito bites, the following actions are recommended:

• Use of Repellents: Apply approved insect repellents on exposed areas of the skin.
• Proper Clothing: Wear light-colored garments that cover most of the body.
• Personal Hygiene: Maintain good hygiene to minimize sweat and body odor buildup.
• Avoid Alcohol Consumption Outdoors: Limit alcohol intake in areas with a high presence of mosquitoes.
• Protected Environments: Use mosquito nets and ensure windows and doors have protective screens to prevent mosquitoes from entering.

Understanding the factors that attract mosquitoes is essential for implementing effective prevention strategies and reducing the incidence of bites, especially in areas where mosquitoes are vectors of diseases.
