To prevent ant invasions, how far should trees and shrubs be trimmed back from building exteriors?

Maintaining a distance of 18 inches when trimming trees and shrubs back from building exteriors is important for several reasons related to pest management and structural integrity. This distance helps to create a clear zone that reduces the pathways insects, including ants, might use to access the building. By keeping vegetation trimmed back significantly, you minimize the potential for ants to use branches or foliage as a bridge to enter structures, which can be crucial in preventing infestations.

Additionally, an 18-inch buffer can enhance ventilation around the building foundation and walls, which may help reduce moisture buildup that attracts pests. Properly managing the space around buildings not only deters pests but also helps to protect the structure from potential damage caused by damp vegetation and ensures that maintenance tasks, such as pest inspections, can be performed more effectively.
