This morning's Courtenay aerial application began at 5:44 AM under ideal conditions.  The treatment was completed in 45 minutes.  The final ground application in the Rockland Heights neighborhood was completed today under cool but ideal conditions.  These final treatments signify the end of the 2018 gypsy moth eradication program.   No further treatments are planned and treatment plans, if required, will be announced in the late fall when CFIA's pheromone trapping results have been assessed.  

May 28, 2018 - Last Surrey Treatment Completed; Campbell River Moved Up One Day To May 31st

The final treatments began today in Surrey and on Thursday, May 31st for both Courtenay and Campbell River.   The Campbell River date was moved up one day due to predicted rain on Friday.   The aerial treatment in Courtenay will begin at about 6 AM and be completed in less than one hour.  The ground treatment in Campbell River should start at about 8 AM and continue until the entire treatment block is completed but should be done in one day.   Once completed, monitoring for surviving moths will be carried out by the CFIA over the summer with the results being available in the late fall on this web site. 

May 24, 2018 - Final Agassiz Treatment Completed

The Agassiz ground program is now completed.  Monitoring by CFIA for surviving gypsy moth populations will be done this summer and the results will be available in the late fall.    The next area to be treated is the final application in Surrey on Monday, May 28th.  The final aerial application in Courtenay is scheduled for ~6 AM on Wednesday, May 31st while the final ground application of Campbell River is currently on June 1st, weather permitting.

December 13, 2017 - 2018 Treatment Plans Announced

2017 pheromone trapping conducted by the Canadian Food Inspection Agency (CFIA) revealed four sites with growing populations of gypsy moth that were recommended for eradication treatment in 2018.  Three will be treated using ground spray equipment while the fourth will be treated from the air.    The four treatment areas are as follows:

62 hectare Ground Spray - Port Mann/Guildford, North Surrey

A population of gypsy moth appeared to be establishing itself in the northwest corner of the Guildford neighborhood in Surrey, B.C. Trapping results for the last four years have shown gypsy moth surviving in this residential area and in undeveloped city land bordering the former Surrey Landfill and the southern approach to the Port Mann Bridge. A 24 hectare ground application of Btk was conducted in May 2017.  However, trapping results in the summer of 2017 revealed that the population continues to thrive, likely within the dense vegetation along the slopes below the residential area.  A second, more intensive ground application will be conducted in the spring of 2018 that will target the previously untreated vegetation below the subdivision.  An expanded treatment of residences that could potentially have received dispersing larvae will also be conducted at that time. Three applications are required and the treatments will be conducted during daylight hours.  Residents will be given notice, prior to treatments commencing,  to close windows and vents, and to cover or move indoors any items not be sprayed.  

41 hectare Ground Spray - Agassiz

A single trap containing two moths was collected in 2016 and follow-up trapping at a higher density revealed another four moths collected in four traps in the same area in 2017.   A decision to treat the area with Btk was made and a boundary was drawn that includes the area where there is a high probability that gypsy moth are thriving.  

45 hectare Ground Spray - Campbell River

A single trap containing two moths was collected in 2016 and a higher density trapping grid placed in 2017 found another eight moths in two traps located very close to the 2016 find.  The treatment boundary covers the area where the moths are likely to be found and will be treated with ground spraying equipment in April through June, 2018.



94 hectare Aerial Spray - Courtenay

After three successive years of male moth catches at this location, the decision has been made to treat the area using Btk applied from an aircraft.  Aerial treatment is the only practical means of applying the product due to the size and terrain of the treatment area. 

2017 Trapping Results

During the summer of 2017, the Canadian Food Inspection Agency and FLNRORD staff placed pheromone traps to detect the presence of male gypsy moths that have been brought into B.C. from infested parts of eastern North America.   A total of 68 moths were caught in 30 different locations, primarily in the Lower Mainland/ Fraser Valley and southern Vancouver Island.  The very first moth was caught on Haida Gwaii near Queen Charlotte City.  One of the moths has been identified as being an Asian gypsy moth and the site where it was caught near Cowichan Bay will be intensively trapped next summer.    

Green Waste Information for Surrey & Delta Residents

Help Keep B.C. Gypsy Moth Free! Gypsy Moth has been located and is under eradication in Surrey and Delta. You can help prevent Gypsy Moth from establishing permanently in B.C. by inspecting your outdoor plant waste for egg masses and ensuring all green waste goes in your green bin.

If you are a resident of Surrey and have large green waste items that do not fit inside your green waste bin, call the City of Surrey Waste Collection Hotline at 604-590-7289. If you are a resident of Delta, ensure that all green waste is contained in green cans or kraft paper bags. Delta residents can drop off large quantities of green waste, free of charge, at Enviro-Smart Organics (4295 72 Street).
