The hot and humid summer weather has arrived in Toronto and with it comes the pesky mosquito.
Not only are the tiny insects next to impossble to spot when they're keeping you awake at night, they can also be a health concern.
Toronto Public Health has already taken steps to control the mosquito population - and the spread of the mosquito-borne West Nile Virus.
The flu-like symptoms of an infection include headaches, fever, and sore muscles.
While most patients will experience little to no symptoms of West Nile, about 1 percent of those infected will need to be admitted to hospital.
The illness can be deadly for the elderly and those with compromised immune systems but fatal cases are extremely rare.
City crews have started making the rounds across Toronto, clearing standing water and soon will begin spreading larvicide around at catch basins.
To minimize your risk of infection, Toronto Public Health recommends wearing Health Canada-approve mosquito repellant when outdoors, along with long-sleeved clothing when going out in the evening and early-morning hours.
The agency also recommends clearing and standing water from the area around your home, as pools of water make ideal places for the insects to lay their eggs.
