Which of the following best describes mechanical controls?

Mechanical controls refer to strategies and devices used to directly prevent or reduce pest infestations. These methods can include traps, barriers, and manual removal of pests. The focus of mechanical control is engaging techniques that directly disrupt the life cycle or presence of pests in a physical manner.

For example, a physical trap can catch rodents, or using insect vacuums can directly remove pests from an area. This is distinct from changing habitats or relying on genetic modifications, which are other pest management strategies but do not fit the definition of mechanical controls.
