A brief description of the IPM program:
Purdue University’s Grounds staff is responsible for maintaining the iconic appearance of the West Lafayette campus and provides multiple services including the removal of pests within academic and Residential Life buildings. This service is provided utilizing Integrated Pest Management (IPM), which combines biological, cultural, physical, and chemical tools in a way that minimizes economic, health, and environmental risks.

Staff identify which pests to target and determine the best eradication approach for each pest. Non-chemical options are evaluated and implemented, if possible, prior to resorting to chemical sprays and poisons, which can cause allergic reactions if unwanted contact occurs with people and damage the environment. In some situations, chemical-free forms of weed and pest management include insecticidal soap, weed removal by hand, and companion planting. Monthly preventative maintenance checks are performed and if the building or outdoor space needs to be serviced more frequently, the respective building owner places a Work Order. 

If alternative methods fail, least-toxic pesticides will be used prior to resorting to the use of higher toxicity pesticides or baits. If a chemical application is required, spot spraying should be utilized instead of a general full coverage approach, and the least hazardous pesticide should be selected. Staff who apply regulated pesticides must maintain their Indiana 3A and/or 3B certifications (3A covers pesticide or fertilizer applications to ornamental plantings and 3B covers pesticides or fertilizers on turf areas).
