For effective pest control, what is a critical area to apply termiticide around?

Applying termiticide around foundation walls is crucial for effective pest control, particularly in preventing termite infestations. The foundation of a building serves as a primary entry point for termites, which are attracted to the moisture often present in or near the foundation. By treating this area with termiticide, you create a chemical barrier that helps to protect the structure against subterranean termites that tunnel through the ground to find food sources, which often include wood in or around the home.

While other options like windows, roofing, and doors can also be potential entry points for insects, they are not as directly associated with termites as the foundation walls. Termites typically access a building from the ground up, making it essential to focus treatments on the foundation to establish a strong defense against their activity.
