1 It was a mild winter and it has been raining heavily lately. Will 2023 be a strong mosquito summer?
I can’t say that right now. The occurrence of mosquitoes also depends on how much and how much rain falls. However, how long mosquitoes stay in water spots also plays a role, as mosquitoes have a two-week development period. “They lay their eggs in bodies of water, and even small puddles such as flower pots or clogged gutters are sufficient,” says Gernot Kunz of the Institute of Biology at the University of Graz. If the water is inactive for two weeks, mosquitoes can develop and hatch. “If the dry phase lasts longer than two weeks, the mosquito population is naturally exterminated,” explains the zoologist.
