The City of Edmonton has launched a fourth mosquito control campaign.
Helicopter and ground crews are being deployed across Edmonton to control mosquitoes following recent heavy rainfall.
City staff spent the weekend surveying standing water in and around the city and determined there was enough larvae to warrant a fourth round of spraying.
The fourth campaign, which began Monday morning, includes three helicopters and crews working from truck and on foot. It’s expected the spraying work will take about seven to 10 days to complete, provided weather conditions co-operate.
In addition to treating larvae, crews will target adult mosquitoes near major festival and event sites, given the right conditions, which include the presence of perimeter vegetation, the potential effectiveness of the additional control and weather conditions such as wind or rain.
This year’s mosquito population is higher than in recent years and exceeds Edmonton's 25-year average. But so far, the city’s monitoring has not detected the mosquito species that is the main transmitter of West Nile virus in the Edmonton area.
People are advised to protect themselves by using repellent and wearing pants and long-sleeved shirts when outdoors. Light-coloured, loose-fitting clothing is recommended.
