Invasive 'Asian tiger' mosquito known as 'aggressive biters' found in Ontario
A dangerous invasive mosquito known for its "aggressive daytime" biting and ability to spread harmful viruses has been found in Ontario.
Niagara Region Public Health (NRPH) announced on Tuesday that it had identified a single Aedes albopictus mosquito, better known as the Asian tiger mosquito.
While the invasive insect — native to Southeast Asia but found in Lincoln, Ont. — tested negative for mosquito-borne viruses, these mosquitoes simply having a foothold in Ontario is something officials will want to keep tabs on.
The species was first detected in the province in 2016, when a specimen was found in Windsor, and the latest finding has prompted officials to warn the public about the risks these insects pose.
"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," said Dr. Hamidah Meghani, Associate Medical Officer of Health at Niagara Region Public Health.
"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."
NRPH warns that Aedes albopictus "is capable of transmitting mosquito-borne viruses, including West Nile virus (commonly found in Ontario), dengue, Chikungunya and Zika."
However, the local health agency stresses that "It is important to note that there has been no change in the risk associated with these viruses in our community."
Tuesday's announcement came just weeks after NRPH announced it had identified the first West Nile virus-carrying mosquito of the season.
Residents are advised to minimize risks by clearing any standing water, whether from buckets, bird baths, old tires, or even your pets' outdoor dishes. Basically, anything where still water collects can quickly become a breeding ground for mosquitoes, so you'll want to make sure your eavestroughs and gutters are clear.
NRPH says it will continue its mosquito surveillance, management and prevention programs and will keep the public updated along the way.
