Monitoring traps are placed in areas where pests have been reported. The numbers of pests caught are counted to determine if action thresholds have been reached and if control measures are necessary. When the number of pests becomes greater than the action threshold, the pest control contractor takes action. He or she may physically remove the pests or suggest changes to the habitat so that pests can't get to food, shelter, and water. Records Accurate record keeping allows the pest control contractor to evaluate the success of the IPM program.
Records also help in forecasting the appearance of seasonal pests to predict future pest outbreaks.
Whether an IPM program raises or lowers costs depends on housekeeping, maintenance, and pest management policies. The costs of setting up an IPM program can also depend on whether the pest management services are contracted out or provided by in-house staff. Be aware, though, that some states require in-house personnel to become certified before they can apply pesticides. This document was originally taken from EPA sources and is in the public domain.
