6 grandma’s tricks that don’t work (at all) against mosquitoes
The beautiful days are coming back and with them, our worst enemies: mosquitoes. If you want to protect yourself effectively, here are the 6 “grandmother’s tricks” that you must avoid, because they are ineffective.
Vectors of many diseases (malaria, dengue fever, zika, etc.), mosquitoes are attracted by the carbon dioxide (CO2) that is emitted through the mouth and nose when breathing, but also by heat emitted by the body (they perceive infrared) and by certain molecules present on the skin – lactic acid and ammonia, for example.

In addition, some common sense measures can prevent bites:
- wear covering and loose clothing when walking (if possible white because, it has been proven, mosquitoes are attracted to dark clothing)
