Sealing cracks, crevices, and small openings in buildings is an example of which type of pest management method?

Sealing cracks, crevices, and small openings in buildings is a form of physical pest management. This method aims to prevent pests from entering a structure by eliminating potential entry points. By physically blocking these access routes, the likelihood of pest infestation decreases significantly, thus providing a proactive means of pest control.

Physical pest management encompasses a variety of techniques that rely on barriers, traps, and other non-chemical means to manage pests. In this context, sealing openings is a direct intervention that impedes pests, making it an effective strategy for maintaining a pest-free environment.

The other methods mentioned, such as genetic, biological, and cultural, focus on different strategies that do not involve the direct physical alteration of the environment to manage pest populations. Genetic methods often refer to altering pest organisms through breeding or genetic modification, biological methods utilize natural predators or parasites to control pest populations, and cultural methods involve changing agricultural practices or environmental conditions to deter pests.
