Poisonous mosquitoes are poisonous. Mosquitoes that breed and grow in dark and humid places often take feces and other filth as their "home", which leads to their own "poison" and spreads related diseases to people through bites.

After the arrival of summer, mosquitoes breed, especially in the rainy season, and mosquito larvae multiply in large numbers in the flood. Mosquito bites make it difficult for people to sleep, and they also spread diseases. When a mosquito bites, it secretes an organic acid, formic acid, in its mouthparts, and its chemical composition is HCOOH. This substance can cause muscle acid.

Mosquito's blood-sucking habit: Mosquitoes also transmit diseases through blood-sucking. Understanding mosquito's blood-sucking habit can reveal its relationship with diseases. Only female mosquitoes suck blood, and female mosquitoes must suck blood on their ovaries to develop and reproduce. Female mosquitoes begin to suck blood 2 ~ 3 days after emergence, and many factors such as temperature, humidity and light can affect mosquito's blood-sucking activity.

When the temperature is above 10℃, blood feeding begins; Generally, Aedes mosquitoes mostly suck blood during the day, while Anopheles mosquitoes and Culex pipiens mostly suck blood at night. Some prefer human blood, while others like to suck the blood of domestic animals, but there is no strict selectivity, so mosquitoes can spread human and animal diseases.
