will began in early Summer, 2007 with trap results being compiled in the
late Fall, 2007. Treatments, if necessary, will be formally
announced in December, 2007. Trapping results and treatment
recommendations will be posted on this web site and announcements will
be made using the listserver and from media news releases.

SPRAY DATES
Application dates are selected based on
the estimated peak emergence and development rates of gypsy moth
caterpillars. Since these rates are temperature dependent, the
dates may change. Poor weather (rain, high winds) may cause
cancellation of the spray but it will resume as soon as the weather and
other conditions become favourable. Every effort will be made to
provide notification of changes to the schedule when they occur.
Updates will be posted on this site, sent
via
listserve e-mail, and on the outgoing phone message on the toll-free
gypsy moth information line (1-866-917-5999)
SPRAY FORMULATIONS
Two different Btk formulations were
used in 2007 as they were in 2006. Saanich, Courtenay and Colwood will
be treated with Foray
48B. A second year of treatment with Dipel 2XDF was applied on Salt Spring Island since it is an
acceptable product for maintaining organic farm certification of two
farms in the spray zone. A concession was made for some residents
of Cedar Hill to allow them to choose which Btk formulation they wished
to be treated with by posting signs visible to spray technicians. More detailed information on these
products - including their labels - is available on the
Btk Links page.
For more information on Mass
Trapping, go to the
Alternatives Treatment page.
Other locations where male gypsy moth adults
were located in the summer of 2006 (see trapping
history) were trapped at various trap densities and monitored in the summer of 2007.
See 2007 trapping results page.
