Why do we get bitten by mosquitoes and how to avoid it?

Discover the mystery behind one of the most common questions of the summer: Why do mosquitoes bite us? Beyond the nuisance they represent, there is a fascinating biological explanation that reveals the complexity of these tiny creatures.

In this post we will unravel the secrets of their behaviour, exploring everything from their nutritional needs to the factors that make us attractive to them. And of course, we'll tell you about the role of mosquito nets in preventing bites and their dangerous effects.

What are mosquitoes and how do they work?

Mosquitoes are flying insects known primarily for their ability to bite and feed on the blood of humans and animals. This characteristic is exclusive to females, who need the nutrients from blood for the development of their eggs.

Equipped with a specialised mouthpiece, females pierce the skin of their victims and suck out the bloodThey inject saliva that prevents clotting and triggers inflammatory reactions. Although often seen as annoying, mosquitoes play important ecological roles, including pollination and serving as a food source for other species.

Factors that attract mosquitoes

Mosquitoes do not choose their victims at random; specific factors attract them to us. From our body chemistry to our lifestyle choices, here we explore what makes us irresistible to these insects.

• Carbon dioxide and its attraction: Mosquitoes are attracted to the CO2 we exhale. This gas serves as an indicator to locate their food sources, being more attracted to those that emit larger amounts, such as adults and active people.
• Body heat and odour: Our body temperature and the unique odours we emit, especially when we sweat, act as magnets for mosquitoes. Compounds such as lactic acid present in our sweat are especially attractive to them.
• The role of blood group: Research suggests that people with type O blood are more likely to be bitten than those with other blood types. Mosquitoes seem to prefer this blood type, possibly due to chemical signals emitted through the skin.
• The influence of beer and other substances: Consuming alcohol, and in particular beer, can increase the chances of being bitten by mosquitoes. Ethanol in our sweat and increased body temperature are thought to contribute to this attraction.
• Clothes and colours: Do they influence stings? Dark colours such as black and red tend to attract mosquitoes more. Their vision is adapted to detect these shades easily, which makes them more likely to target people who dress more vibrantly.

Prevention and protection

Prevention and protection against mosquito bites are essential to enjoy the outdoors without the discomfort and health risks that these insects can bring. Implementing effective strategies can make a difference to our quality of life during the warmer months.

Strategies to avoid bites

The first line of defence against mosquitoes includes the use of insect repellents approved, containing DEET, picaridin or natural oils such as lemon eucalyptus, which have been shown to be effective.

Wear light-coloured clothing and covering most of the body can also deter mosquitoes from biting. In addition, installing mosquito nets on windows and doors is a preventive measure that allows ventilation of indoor spaces while blocking access to these flying insects.

Avoiding being outdoors during dawn and dusk, when mosquitoes are most active, can also significantly reduce the number of bites.

Mitigating the effects of stings

Despite the best preventive measures, mosquito bites can still occur. In these cases, it is important to treat the affected area to relieve itching and inflammation. Apply cold compresses or products with calamine can offer immediate relief.

The oral or topical antihistamines can also be helpful in reducing the allergic reaction. Keeping the skin clean and avoiding scratching will help prevent secondary infections, ensuring a quicker and smoother recovery. In this other post we tell you about 14 remedies to avoid mosquito bites.
