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)
