Current Status of
Gypsy Moth Treatment Operations in British Columbia
2006
TREATMENT DATES
The last
application for Salt Spring Island was completed on June 5th (the 2 day
spray was completed in one day). Both Saanich and Nanaimo were
treated for their third and final time on May 30th (Tues.) and May 31st
(Wed.), respectively (see details below).
Three treatments were scheduled for each
location and were spaced about 7 to 14 days apart. The schedule
varied depending on weather that drives the rate of insect
development and also may delay spraying if it is too wet. A developmental rate model is being used
to time the spray when it will be most effective. The model
indicates when the next application will most likely occur.
Contractor crews went
door-to-door in advance of the spray crews to warn home owners that
their properties will be treated. If necessary, the homeowner
could cover or move items like lawn furniture, windows, cars, etc.
that they may not want to be covered by spray deposits. Such
deposits are readily removed with soap and water with some light
scrubbing. Otherwise, the deposits will eventually weather and
disappear after several days exposure to normal weather conditions.
Pets that may be easily frightened by the spray crews should be brought
indoors while the treatment is occurring. The spray does not pose
any harm to pets including fish. If you wish to avoid deposits
entering the home, simply close doors and windows for up to one hour
after the spray.

SPRAY FORMULATIONS
Two different Btk formulations were
used in 2006. Saanich and Nanaimo were sprayed with Foray
48B. Dipel 2XDF was used on Salt Spring Island since it is an
acceptable product for maintaining organic farm certification of two
farms in the spray zone.
OTHER TREATMENTS
Both the Nanaimo and Salt Spring Island
treatment areas will also be mass trapped this summer. Mass trapping of several other sites is
also being planned in S. Duncan, Gabriola Island, Saanich (Cedar Hill
Golf Course), Sidney and Langley. For more information, go to the
Alternatives Treatment page.
Other locations where male gypsy moth adults
were located in the summer of 2005 (see trapping
history) will be trapped at various trap densities and monitored in the summer of 2006.
