In other situations, winter treatment may be most effective. Probable duration of control. Site-specific constraints that might affect use of control method. If specialized equipment is to be purchased for the control project, determine the cost of buying, operating and maintaining it, including staff wages and replacement costs. Human safety and health concerns.
