To protect your pergola from termites and other pests, consider using treated wood during construction. Pressure-treated lumber with insect-resistant properties can help prevent termite infestations. Regular inspections of the pergola’s structure for signs of pest activity are important, as early detection can prevent significant damage. Applying a protective sealant or coating to the wood can act as a deterrent against pests. Additionally, keeping the area around the pergola clear of debris and vegetation can discourage pests from nesting near it.
