Final answer:
A vertical treatment around a building creates a continuous chemical barrier that prevents termite infestation by deterring them from constructing mud tubes used for travel.
Correct option is
C. Create continuous chemical barrier
Step-by-step explanation:
The reason for making a vertical treatment around the building/home perimeter is to Create a continuous chemical barrier. This barrier is important for protecting the home from various pests, particularly subterranean termites, by preventing them from entering and infesting the building. By creating a treated zone in the soil around the building, homeowners can deter termites from constructing their mud tubes, which they use to travel and access wood, one of their primary food sources.
Creating a continuous chemical barrier around the building/home perimeter is a preventive measure commonly used to combat subterranean termites. This treated zone acts as a deterrent, inhibiting termite entry and minimizing the risk of infestation by disrupting their typical pathways, such as mud tubes. The chemical barrier serves as a proactive approach to protect the structure and its wooden components, contributing to the long-term integrity and durability of the building.
