What does mechanical control involve in pest management?

1. Using substances that repel pests.

2. Using barriers and traps to control pests.

3. Altering habitats to deter pests.

4. Applying insecticides for quick results.

The correct answer is: Using barriers and traps to control pests.

Mechanical control in pest management refers to the use of physical methods to manage pest populations without the use of chemicals. This approach is centered around creating barriers, traps, and other devices to physically prevent pests from causing damage or to capture them. Utilizing barriers can include various strategies such as screens, nets, or physical structures that prevent pests from accessing certain areas. Traps are another vital component, which can be designed to catch specific pests, reducing their numbers effectively. These methods are particularly beneficial because they tend not to cause harm to non-target species or the environment, making mechanical control a desirable option in integrated pest management practices. By focusing on physical means to manage pest populations, mechanical control supports sustainable pest management strategies while minimizing reliance on chemical substances. This aspect is essential for maintaining ecological balance and promoting environmentally friendly pest management solutions.
