Chestermere is using a science-based, environmentally friendly approach to mosquito control. Instead of spraying in parks, City crews treat small standing pools of water with larvicide. This prevents mosquito larvae from turning into biting adults and tackles the problem at the source.
Why larvicide works best
After July’s record-setting rainfall, standing water is everywhere from ditches and storm ponds to puddles in backyards. That’s where mosquitoes breed. Larvicide stops them before they hatch, making it far more effective than spraying.
Spraying only affects adult mosquitoes in a single location, and only for a short time. With water across both public and private land, it would not provide lasting results.
Looking ahead
- Cooler nights and drier weather will naturally bring mosquito numbers down.
- The City will keep monitoring and adjust the program as needed.
- Residents can help by tipping out standing water around their homes. Buckets, birdbaths, planters, and toys are common hotspots.
Our goal is to manage mosquitoes where they actually start – in standing water,” said James Blair, Parks Manager. “Larvacide is more precise, environmentally friendly, and ultimately more effective than spraying. Residents can make a big difference too by emptying water around their homes.”
FAQ: Mosquito Control in Chestermere
Why doesn’t the City Spray?
Spraying only kills mosquitoes in one spot at one time. With so much standing water after heavy rain, new mosquitoes would appear almost immediately.
Is larvicide safe?
Yes. The product used targets mosquito larvae and does not harm people, pets, or wildlife when applied properly.
What can I do to help?
Eliminate standing water around your home. Empty buckets, toys, birdbaths, and plant saucers after rain. Even a small puddle can produce hundreds of mosquitoes.
Will mosquitoes go away on their own?
Numbers usually drop as the weather turns cooler and drier. The City monitors conditions and will adjust treatment if needed.
