Aggressive Asian Tiger Mosquito Detected in Niagara Region

Public health officials in the Niagara Region have confirmed the detection of a single Asian tiger mosquito, identified as Aedes albopictus. This species is known for its aggressive daytime biting habits, distinguishing it from other mosquitoes found in Ontario. The discovery was made through the region's ongoing surveillance program in Lincoln, Ontario.

While the Asian tiger mosquito is capable of transmitting viruses such as West Nile virus, dengue, Chikungunya, and Zika, Niagara Region Public Health stressed that there has been no change in the risk associated with these viruses in the area. The detected mosquito tested negative for mosquito-borne viruses.

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, emphasized the importance of community awareness regarding new mosquito species identified through surveillance. She advised residents to take precautions against mosquito bites, especially when outdoors, by employing methods such as emptying standing water from containers and using insect repellent. The mosquito is native to Southeast Asia and has been previously found in Windsor since 2016.

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.
