Which of the following is a preventative measure against termite infestations?

Using treated wood for construction is a key preventative measure against termite infestations because treated wood is chemically modified to resist moisture and damage from pests, including termites. This treatment makes the wood less attractive as a food source for termites, thereby helping to protect the structure from potential infestation. In environments where termites are prevalent, incorporating treated wood can significantly reduce the risk of termites establishing themselves in a building.

When constructing a building or undertaking renovations, using treated wood is an effective strategy that increases the longevity of the wood and enhances the overall durability of the structure. It is particularly important in areas known for high termite activity, as it serves as a barrier against one of the most destructive pests that can undermine the integrity of buildings.

Other options may not provide the same level of protection. For instance, planting bushes near the foundation can create moisture-retaining environments that may attract termites and provide them with shelter. Flooding the area can lead to increased moisture levels, also making it more conducive for termite infestations. Leaving gaps in the foundation compromises structural integrity and allows for easier access for termites to enter the building. Therefore, employing treated wood is a proactive approach that effectively mitigates the risk of termite invasions.
