In the last 20 years, the deer population has rapidly increased to unprecedented numbers.  During the cold, snowy winter months, deer lose many of their food sources such as flowers and grass.  Unfortunately, evergreen shrubs become their new food supply.  To combat this problem, a deer repellent spray is applied to the shrubbery and evergreens in November and January.  This spray deters the deer from eating your valuable landscape without causing harm to the deer.
