Using spot treatments of pesticides is most appropriate when only small areas of infestation are present. This method allows for targeted application, minimizing pesticide use while effectively managing pest populations in localized areas. Spot treatments help to reduce the potential for environmental impact and limit exposure to non-target organisms by treating only the infested areas instead of applying pesticides more broadly across larger fields.

The use of spot treatments is particularly beneficial in scenarios where pests are isolated rather than widespread. This targeted approach also conserves resources and can lower costs, as large volumes of pesticide are not necessary when addressing a specific problem. By focusing the treatment where it's needed, pest management efforts can be more efficient and effective.
