What is the main benefit of liquid termiticides?

The primary benefit of liquid termiticides lies in their ability to create a barrier in the soil. This barrier prevents termites from accessing the structure, acting as a protective shield. By establishing a continuous and treated zone, liquid termiticides effectively block termite pathways, which is crucial for preventing infestations.

This barrier is particularly significant because it not only stops existing termites from entering but also helps to deter future invasions. It can be applied around the foundation of a building and in areas where termites are likely to penetrate, thereby enhancing the overall structural integrity against these pests.

The other options identify functionalities that are not the central role of liquid termiticides. For instance, while some products may kill termites on contact or deter them, these aspects are secondary to the main purpose of creating a protective barrier. Therefore, the focus remains firmly on their barrier-forming capability, which is critical for effective termite management.
