What type of control does a steel mesh termite shield represent?

A steel mesh termite shield exemplifies mechanical control because it serves as a physical barrier designed to prevent termites from gaining access to a structure. This type of control involves using non-chemical methods to directly obstruct or eliminate pests. The physical nature of the mesh acts as a deterrent, preventing termites from tunneling or accessing vulnerable areas of buildings, thus reducing the likelihood of an infestation.

Mechanical control strategies, such as the use of barriers, traps, and physical removal, are often employed to manage pest populations in an environmentally friendly and safe manner. In contrast, chemical control entails the application of pesticides, biological control relies on introducing natural predators or pathogens to manage pest populations, and behavioral control focuses on altering the behavior of pests to reduce their impact. The use of a steel mesh termite shield distinctly aligns with the principles of mechanical control due to its structural intent and non-involvement of chemical agents.
