In pest control practices, what does the term "Barrier" refer to?

In pest control practices, the term "Barrier" specifically refers to a substance that prevents pest entry. This concept is essential in preventing pests from infiltrating structures or areas where they could cause damage or health issues. Barriers can be physical, such as screens or seals, or chemical, involving substances that deter or repel pests.

Using barriers effectively can help maintain a pest-free environment by addressing the root of the problem—preventing pests from gaining access in the first place. This proactive approach is often more efficient than reactive measures, such as trapping or baiting, which may deal with pests after they have entered. Understanding the role of barriers in pest management is crucial for implementing a comprehensive pest control strategy.
