Is O-type blood the most attractive to mosquitoes? What kind of people are mosquitoes most likely to target

Summer has arrived, and the recent continuous heavy rains have also triggered a new wave of "human-mosquito wars" this year. There are many ways to prevent mosquitoes circulating among citizens. I wonder if these ways of "fighting wits and courage" with mosquitoes are scientific?

Is O blood type the most attractive to mosquitoes?

There is no correlation between mosquito bites and blood type. Mosquitoes use the carbon dioxide sensors and infrared sensors on their bodies to detect carbon dioxide emitted by the human body and sense the human body surface temperature to find people and bite them. Therefore, people with high metabolism, such as children, pregnant women, and people who have just done strenuous exercise, are more attractive to mosquitoes; the elderly and the weak have relatively low metabolism, so the chance of being "targeted" by mosquitoes will be smaller.

In addition, mosquitoes' visual systems are most active in dark environments, and the less reflective black color is most attractive to them. So, mosquitoes like black, warm, and moist objects, like your slightly sweaty black T-shirt. If you want to avoid mosquitoes, avoid wearing this kind of clothing next time you go out.

Can placing opened wind oil or cooling oil in the room, applying sesame oil, sesame oil, camphor oil, lavender essential oil, mint, perilla or tomato juice, or Huoxiang Zhengqi water or Shidi water on the body, or taking vitamin B1 and garlic, etc., prevent and treat mosquito bites?

Fengyoujing and Qingliangyou are only effective in reducing swelling and relieving itching after being bitten by mosquitoes, but they themselves have no effect on repelling mosquitoes and cannot prevent you from being bitten by mosquitoes. There is no scientific basis for such methods as taking vitamin B1, garlic, or applying sesame oil, mint, basil or tomato juice on your body.

Some natural plants do have certain mosquito repellent functions, such as lavender, mosquito repellent grass, and pyrethrum, but their biological activity is low and the mosquito repellent effect is very limited; camphor oil has a better effect on repelling cockroaches.

Will long-term use of the same mosquito coil or the same mosquito repellent product make mosquitoes resistant? Can mosquito coils of different brands be mixed and used at the same time?

Resistance is an inevitable result of long-term use of pesticides. Planned rotation of insecticide products can slow the process of mosquitoes developing resistance to certain insecticides. The insecticidal active ingredients of mosquito coils of different brands may be the same or different, and there is no necessary connection between them and whether they can be mixed.
