It is the most active period for mosquitoes in early autumn in Beijing every year. The temperature during autumn is suitable for the reproduction of mosquitoes. Entering the peak period of reproduction, the mosquitoes need more blood to meet the nutritional needs of laying eggs and reproducing offspring. Therefore, mosquitoes bite more fiercely and frequently, taking more blood after the beginning of autumn. Therefore, there are sayings such as "Mosquitoes bite fiercely on August 8 of Chinese calendar" and "Mosquitoes are as fierce as tigers after the beginning of the autumn" to describe the increase in mosquito bites after autumn.

Mosquito bites are also very easy to spread insect-borne infectious diseases. For example, malaria is a blood parasitic disease caused by the bite of Anopheles (also known as Anopheles mosquitoes) and is usually called "cold and hot disease" or "shaking disease". Generally, the disease will occur 10 to 20 days after the bite. Before the onset of the disease, there are symptoms such as fatigue, discomfort, and anorexia. When the disease occurs, it will go through four stages, chill period, fever period, sweating period and interval period. In addition, mosquito bites may also cause epidemic encephalitis B, the clinical manifestations of which are high fever, impaired consciousness, meningeal irritation signs, etc., posing a serious threat to health.
