Sources: 5. Developments: 2. Experts warn that mosquito populations may surge during autumn months due to mild, humid weather and increased rainfall. In the United Kingdom, the London School of Hygiene and Tropical Medicine has noted that current weather patterns involving higher temperatures and humidity are ‘perfect for a potential surge’ in local activity. Dr Yasser Qureshi, an AI researcher specializing in mosquito behavior, explained that rising global temperatures allow populations to thrive. Higher temperatures accelerate the development of eggs, larvae, and pupae, while humidity prevents insects from losing water through evaporation. This combination allows for faster breeding cycles and longer survival rates. In the UK, native species like the common house mosquito and the banded mosquito are driving this seasonal rise. However, health officials are also monitoring the potential for non-native species to establish themselves due to long-term climate change, including the invasive Aedes aegypti mosquito, which can carry viruses such as Zika and dengue. ## Timeline ### 2026-09-16: Mosquito populations expected to rise due to warm weather Experts warn that warm, humid weather and rainfall are driving increased mosquito activity and breeding cycles, raising concerns about native population surges and the spread of invasive species. 2 sources. https://clstr.news/cluster/mosquito-populations-expected-to-rise-due-to-warm-weather ### 2026-08-22: Belgium mosquito populations rise following rainfall Increased rainfall in Belgium is boosting mosquito populations. Experts warn that standing water can lead to rapid breeding and the potential spread of exotic species like the Asian tiger mosquito. 3 sources. https://clstr.news/cluster/belgium-mosquito-populations-rise-following-rainfall --- Cite as: Rising mosquito activity in the United Kingdom.
