How Common Are Mosquitoes in the UK?
WouterCurrently, there are over thirty native mosquito species that are found in the UK. Some species are considered nuisances. Others, however, may carry diseases that affect humans.
The Asian Tiger mosquito (Aedes albopictus), for example, is an invasive species that has spread to south-eastern England. This mosquito carries Dengue and Chikungunya viruses. These viruses are dangerous to humans.
The UKHSA (Health Protection Agency) monitors mosquitoes for disease transmission. These samples are collected weekly and sent to Porton Down labs for analysis. The samples help the UKHSA to track the introduction of new species. They also help the agency to identify new arrivals of disease-carrying mosquitoes.
In addition, the Health Protection Agency helps the Chartered Institute of Environmental Health to set up Mosquito Watch, a voluntary reporting system. The organisation’s aim is to promote public awareness of mosquitoes and encourage individuals to keep their environments mosquito free.
The British Pest Control Association warns the public against increased insect numbers. Climate change is thought to be a contributing factor. This is because warmer temperatures may increase the risk of mosquito introductions. In addition, rising travel and trade could also lead to increased risk.
There have been a number of outbreaks of West Nile disease in Southern Europe. These outbreaks were caused by a species of mosquito that was imported from Southeast Asia. The UK is also prone to outbreaks of chikungunya disease.
There are also reports of human-biting by species that are invasive to the UK. Aedes rusticus has been found to bite during daylight hours in the UK.
