Japanese beetle

Treating City property

Our treatment plan, about the larvicide used, and treatment schedule and map.

How safe is the treatment?

The larvicide, Acelepryn, is not harmful to you, your pets, other animals, or pollinators like bees and butterflies.

It is sprayed directly on the soil and targets root-eating grubs.

Acelepryn is approved for use in Canada by the Pest Management Regulatory Agency of Health Canada and is permitted under our Health Bylaw Section 2.10 (f)

This spring, Park Board staff will treat parks and public lands for the invasive Japanese beetle. 

Treatment will begin on April 7 at George Wainborn Park and continue through the month of April at parks and public lands in the Downtown, West End, Strathcona, Mount Pleasant, Fairview, and Kitsilano neighbourhoods.

We will treat large turf areas and small strips of grass around flower beds, shrubs, and trees.

Watch for signs

Signs will be posted in and around the parks notifying you of upcoming treatment.

Treatment areas

We are treating approximately 25 hectares of park and public land.

This includes all lawns within a 200 metre buffer zone around where Japanese beetle was trapped by the Canadian Food Inspection Agency in 2019 and 2020.

Parks are open

We’re not closing parks, but you should stay off the grass for 24 hours post-treatment to give the larvicide a chance to take effect.

There will be parks staff on site during treatment to explain procedures and answer questions.

Private property

You are not required to treat private property.

However, if your property is in the treatment zone and you want treatment done, it must be applied by a certified pesticide applicator.
