Japanese Beetle - 2025 Technical Session
2025 Japanese Beetle Technical Session
BCLNA and the Japanese Beetle taskforce held this annual online session to provide technical details about the 2025 Japanese Beetle eradication program.
The webinar took place on April 15, 2025 - hosted by the BCLNA, with presenters from the Canadian Food Inspection Agency (CFIA) and the BC Ministry of Agriculture and Food, and support from the cities of Vancouver, Burnaby, Port Coquitlam, and Kamloops to provide municipal context for questions about local details.
This informative webinar provided annual updates on the eradication program and everything industry professionals need to know for working in the regulated area. The recording and slides from the 2025 session can be found below. There is a FAQ section that compiles commonly asked questions from the last few years.

Frequently Asked Questions
No, it was not officially built to replicate another program. However, there are familiar stakeholders and associated colleagues when an invasive species needs to be dealt with, and this was the pattern for the JB effort as well.
- When something is detected in a CFIA survey, they notify the province and begin discussions surrounding the issue. Then they will reach out to stakeholders interested in the impacted areas – both geographic and associated topic groups.
This process follows the approach set out by the British Columbia Plant Protection Advisory Council (BCPPAC), which provides a forum to address plant health and plant quarantine issues of concern to British Columbia.
- Acelepryn is the only larvicide we are using to treat for Japanese Beetle in the 2024 JB program.
- Due to the frequency of applications compared to the lifespan of a Japanese Beetle, there is not currently a concern about resistance: JB has one generation per year, and there is only one application of Acelepryn per year.
- The CFIA has a number of outreach products that can be provided to clients, such as pest ID cards upon request and printable versions on the website.
- They can be directed to the Japanese Beetle Information For Landscape Professionals page on the BCLNA website for up-to-date information.
- Yes, if the shrub roots are cleaned, brushed, shaken and/or washed of any soil chunks larger than 0.5 inches or 12.7 mm, they would not require a movement certificate. Additionally, the soil could also be moved without a movement certificate after being removed from a plant.
- For a detailed description of ‘substantially free from soil’ review the definition given by the CFIA.
- The Treatment Areas are determined by creating a 200 m radius circle surrounding any trap in which a Japanese Beetle has been found. This measurement is considered adequate (factoring in flight habits, etc) and there is not a need to treat outside of this area.
- The Treatment Areas can be found on the Letters to Landowners on the BC Ministry of Agriculture and Food Japanese beetle webpage under the header: “Treatment area maps and communications
- The Regulated Areas are larger zones and encompass Treatment Areas.
- If you have any questions about the Regulated area boundaries, check the CFIA interactive map of Regulated Areas or contact your local municipality.
