What does mechanical pest control involve?

Mechanical pest control involves the use of physical methods or devices to manage pest populations. When utilizing barriers, such as screens, traps, or physical structures, the approach focuses on preventing pests from entering specific areas or reaching plants and products that need protection. This type of control does not rely on chemicals or biological agents; instead, it emphasizes physical means of exclusion and capture.

For example, installing mesh screens on windows can keep insects out of a home, while using traps can effectively catch pests without the application of pesticides. This method is often favored for its low environmental impact and reduced reliance on chemical control.

The other options involve different pest management strategies: using chemicals to kill pests pertains to chemical control, altering pest behavior might use repellents or strategies that impact their habits, and enhancing natural enemy populations relates to biological control methods, where the focus is on fostering organisms that prey on pests. Each of these strategies has its place in integrated pest management, but they are distinct from mechanical pest control, which primarily encompasses physical and structural methods.
