We use a system called integrated pest management (IPM), which examines comprehensive information on the life cycle of pests and their interaction with the environment. This information, in combination with available pest control methods, is used to manage pest damage by the most economical means, and with the least possible hazard to people, property, and the environment. To this end we have minimized herbicide use by using other methods such as releasing beneficial insects to eliminate various pests in the landscape and using plants that are resistant to pests and do well in our environment.
