How do commercial horticulturlalists control the damage done by monarch butterflies?

Commercial horticulturists manage damage from Monarch Butterflies primarily through integrated pest management (IPM) strategies. This includes monitoring butterfly populations, using physical barriers like nets or row covers, and employing biological controls such as introducing natural predators. Additionally, they may employ selective pesticides that target specific pests while minimizing harm to beneficial insects and the environment. Educating staff about the life cycle of monarchs can also help in timing control measures effectively.
