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

Sealing cracks and crevices and small openings in buildings is a prime example of exclusion. This method involves implementing physical barriers to prevent pests from entering structures. By effectively blocking potential entry points, you reduce the chances of infestation, thereby protecting the indoor environment from pests that can cause damage or spread diseases.

Exclusion is a crucial part of pest management strategies because it not only focuses on eliminating existing infestations but also emphasizes prevention. This method is often employed as a first line of defense, making it an essential practice in maintaining pest-free areas in residential and commercial buildings.

The other options, while related to pest management, address different techniques. Trapping involves capturing pests to reduce their numbers, sanitation focuses on the cleanliness of an environment to eliminate food and water sources for pests, and monitoring refers to observing pest activities to identify and assess populations. These methods complement exclusion but do not serve the same purpose of preventing entry.
