Why do mosquitoes exist in Guangdong all year round? But in August and September, the temperature was so high that there were no mosquitoes.

Guangdong is located in the subtropical zone, with a typical subtropical monsoon climate, which is warm and humid all year round. Such climatic conditions provide a suitable environment for mosquito breeding. Mosquitoes mainly breed in warm and humid environment, and the season with abundant rainfall is the peak of mosquito activity. So mosquitoes can be seen in Guangdong all year round.

However, despite the high temperatures in August and September, these two months are often the hottest seasons in Guangdong, with relatively little rainfall and low humidity. Moreover, high temperature sometimes exceeds the most suitable temperature range for mosquitoes to survive, slowing down their reproduction speed. In addition, natural enemies of mosquitoes such as dragonflies are more active during this period, which may reduce the number of mosquitoes. Outdoor hot weather may also make people choose to exercise in an air-conditioned environment. In these environments, doors and windows are usually closed and screens or mosquito nets are used to prevent mosquitoes from entering, so the number of mosquitoes felt indoors will decrease accordingly.

In fact, whether mosquitoes appear in large numbers is also affected by many factors, including local environmental sanitation, the implementation of mosquito control measures, weather changes and so on.
