Question

Using barriers to prevent pest from getting into an area is an example of which type of pest management method?

1) Chemical control
2) Biological control
3) Cultural control
4) Physical control

Answer 1

Barriers to prevent pests from entering an area represent a method of physical control in pest management, distinct from chemical and biological control methods.

Step-by-step explanation:

Using barriers to prevent pests from getting into an area is an example of physical control, which is one of the main methods of pest management. Unlike chemical control, which involves pesticides, or biological control, which uses other organisms to control pests, physical control involves manual or mechanical steps to prevent pests. Barriers such as fences, nets, or screens can help to physically block pests from entering a garden, field, or building without the need for chemicals or biological agents.
