Gypsy Moth Treatment Operations in British Columbia

May, 2004

The results of the 2003 Canadian Food Inspection Agency pheromone trapping program revealed a significant increase in gypsy moth activity and distribution in British Columbia in the Lower Mainland and on Southern Vancouver Island.  Egg masses were also located at two locations - North Delta and Gordon Head (Saanich) - and indicate that gypsy moth populations were reproducing and required eradication efforts to prevent establishment.   The precise location and other details on the eradication projects are available on the 2004 Treatment Area page. 

The following is a detailed description of the treatments that occurred during the spring of 2004.

Saanich - (Mt. Douglas Park/ Gordon Head)
  • Application 3 - final application completed on Monday, May 24th, .  Spraying began at dawn (about 5 AM) and was completed by 6:30 AM under ideal weather conditions.
