Coquitlam’s Pesticide Use Control Bylaw

Since Coquitlam City Council adopted the Pesticide Use Control Bylaw Number 4254 (PDF) on April 23rd, 2012, many pesticides can no longer be used for garden and lawn beautification or maintenance on residential and City land, even if they are legally allowed for sale.

As per the bylaw, retailers of pesticides in Coquitlam must display the Schedule B notice where banned pesticides are for sale. Failure to post Schedule B may result in a $300 fine.

Protect Our Pollinators

Almost 90% of flowering plants need pollinators to reproduce, according to the Pollination Ecology Lab at Simon Fraser University. Although bees are the most frequent pollinators, any insect or animal that visits a flower can be a pollinator, including hummingbirds, butterflies, flies, moths, beetles and bats. Gardening with safe alternatives helps to protect our natural habitat.
