What does physical control in pest management involve?

Physical control in pest management primarily involves strategies that prevent pests from entering an area or eliminate them without the use of chemical pesticides or biological agents. Sealing entry points is a fundamental practice in this regard, as it physically blocks pests from accessing structures where they can cause harm or nuisance. Examples of this can include sealing gaps in walls, doors, and windows, as well as using screens and barriers.

This approach is an essential part of integrated pest management (IPM) because it not only reduces the likelihood of pest infestations but also promotes a healthier environment by minimizing the need for chemicals. By utilizing physical barriers and modifications, property owners can create an environment that is less conducive to pest activity.

In contrast, the other options relate to different pest management strategies. Biological enhancements involve the use of natural predators or parasites to control pest populations, which is distinct from physical control. Chemical pesticides focus on applying substances that kill or repel pests, a method often employed when physical measures are insufficient. Regular monitoring involves assessing pest populations to determine control needs, but it does not incorporate the physical preventive measures that are essential to physical control strategies.
