A mosquito known to be aggressive biters and native to Southeast Asia has been located in the Niagara Region.
A single Aedes albopictus mosquito, known as the Asian tiger mosquito, was found in Lincoln through an ongoing surveillance program, Niagara Region Public Health said this week.
The invasive species has been detected in Windsor since 2016.
Transmit mosquito-borne viruses
The insect, which tested negative for mosquito-borne viruses, can transmit West Nile virus, dengue, Chikungunya and Zika. West Nile virus is commonly found in Ontario.
The agency added that there has been no change in the risk associated with these viruses in the community.
“Unlike the other mosquitoes in Ontario, Aedes albopictus mosquitoes are aggressive daytime biters so protecting yourself and your family anytime you are outside is important,” Dr. Hamidah Meghani, associate medical officer of health at Niagara Region Public Health, said in a statement .
“While the risk of complications from a mosquito-borne virus remains low, keeping the community informed when our surveillance program identifies newer mosquito species is an important part of public health.”
Mosquito spreading around world
According to the European Centre for Disease Prevention and Control, the Asian tiger mosquito has spread around the world by human activities, namely the movement of used tires and bamboo.
The agency said Aedes albopictus is now listed as one of the top 100 invasive species in the world.
“This mosquito is already showing signs of adaptation to colder climates which may result in disease transmission in new areas,” the European Union health agency said in a factsheet .
Niagara health officials said residents can help reduce mosquito populations around their homes by emptying standing water from buckets, animal dishes, bird baths, flowerpots, tarps, and old tires.
It’s also suggested that homeowners clean eavestroughs and gutters while ensuring there is proper water drainage on their properties.
In addition, residents should make sure that door and window screens fit securely and are free of holes.
Spray insect repellents
To prevent mosquito bites when outdoors, the agency said people should use insect repellents that contain DEET, Icaridin, or other approved ingredients at all times of the day, and wear long-sleeved shirts and long pants when possible as well as a hat outdoors. Light-coloured clothing is best as mosquitoes tend to be attracted to dark colours.
The agency said it will continue to run weekly mosquito surveillance, management and prevention programs.
