Japanese Beetle 2021 Spring Update

Published: May 1, 2021

The Japanese Beetle Population in Vancouver is Shrinking

The management program has seen over 80% reductions in beetles captured by traps each year since the program began in 2018. Keys to success included the 2020 Canadian Food Inspection Agency (CFIA) pilot trap project, which saw traps placed in trees. This made the traps less susceptible to vandalism than those previously placed at ground level.

2021 Treatment Area

The treatment area for Japanese beetle is changing in 2021. Each year, the treatment area is reviewed and changes are made based on where beetles were detected over the past two years. Based on beetle detections in 2019-2020, Stanley Park, English Bay, Sunset Beach, Vanier Park, and St. George’s School will be removed from the treatment area. The north half of Hadden Park will be added.

2021 Treatment Schedule

A total of 2,300 traps will be set throughout Metro Vancouver, the Lower Mainland, the Sunshine Coast, and up the Sea to Sky Highway. This year, more canopy traps will be placed in the branches of trees.
Treatment of public lands began on April 7, 2021 and is proceeding on schedule. Weather permitting, all parks within the treatment area will be treated by April 21, 2021. Parks won’t need to be closed, but if you’re visiting, follow the signs and stay off treated grass for the following 24 hours. See the City of Vancouver treatment schedule for dates and locations.
