Sealing cracks and crevices and small openings in buildings is an example of which type of mechanical control method?

Explanation:
Blocking access to a structure with physical barriers is an exclusion approach. By sealing cracks, crevices, and small openings, pests can’t enter to feed or nest, creating a physical barrier that reduces infestations without using chemicals. This differs from pheromone traps, which are used to monitor or disrupt reproduction; thermal treatment, which uses heat to kill pests; and chemical barriers, which rely on pesticides. Sealing openings is a preventive, ongoing measure that strengthens an integrated pest management plan by lowering entry opportunities and the need for other control methods.
