What is Integrated Pest Management?
Integrated Pest Management (IPM) is a very effective and environmentally friendly approach to pest management that relies on a combination of common sense practices. IPM programs use current and comprehensive information on the life cycles 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.
The IPM approach can be applied to all settings, such as the home, garden, and business. IPM takes advantage of all appropriate pest management options including, but not limited to, the sensible use of pesticides.
IPM is not a single pest control method but, instead, a series of pest management evaluations, decisions and controls.
How does Integrated Pest Management Work?
-
- Action Thresholds
Before taking any pest control action, IPM first sets an action threshold. This is a point at which pest populations or environmental conditions indicate that pest control action must be taken. Sighting a single pest does not always mean control is needed. The level at which pests will become a threat is critical to guide pest control decisions.
-
- Monitor and Identify Pests
Not all pests require control. Many pests are not harmful or offensive, and some are even beneficial. IPM programs work to monitor for pests and identify them accurately, so that appropriate control decisions can be made in conjunction with action thresholds. This monitoring and identification removes the possibility that pesticides will be used when they are not really needed or that the wrong kind of pesticide will be used.
-
- Prevention
As a first line of pest control, IPM programs work to manage the area or space to prevent pests from becoming a threat. Prevention includes habitat modification to prevent pests from infesting the area.
-
- Control
Once monitoring, identification, and action thresholds indicate that pest control is required, and preventive methods are no longer effective or available, IPM programs then evaluate the proper control method both for effectiveness and risk. Effective, less risky pest controls are chosen first, including highly targeted chemicals, such as pheromones to disrupt pest mating, or mechanical control, such as trapping or weeding. If further monitoring, identifications and action thresholds indicate that less risky controls are not working, then additional pest control methods would be employed, such as targeted spraying of pesticides. Broadcast spraying of non-specific pesticides is a last resort.
