Integrated Pest Management: Prevention Before Pesticide

The hierarchy the exam expects

First, deny access: seal cracks, repair screens, keep doors closed, install air curtains.
Second, deny food and water: clean spills immediately, store food 6 inches off the floor, empty and line trash containers.
Third, deny harbourage: remove clutter, keep storage areas dry.
Only licensed applicators may apply pesticides, and only after the other measures are in place.

A key question format asks what to do first, and the answer is almost always the prevention step, not the application step.
