Winnipeg begins its annual fight against mosquitoes

The city has started its annual battle against mosquitoes, with crews taking the fight to the air.

As of this week, crews have started the mosquito larviciding program, targeting mosquito larvae in the water before they take flight as adults.

Using ground equipment and four helicopters, crews are monitoring and treating more than 28,000 hectares of water.

When crews are larviciding in public places—like parks, golf courses, or sports fields—the city says it will close the area 20 minutes before and after the treatment. It will also post signs about a day prior.

Right now, the city is just focused on mosquito larvae. It said mosquito fogging would only happen if the requirements—like high adult trap counts, significant rainfall and other requirements—are met.

The city is asking Winnipeggers to join the fight against mosquitoes by getting rid of standing water. Uncovered wheelbarrows, bird baths, and kiddie pools can be a breeding ground.

More details can be found on the city’s insect control website.
