What should be done about any wood directly against a house?

Wood that is directly against a house can increase the risk of infestation due to several factors. When wood is in direct contact with soil or moisture, it creates an ideal environment for pests like termites. These insects thrive in damp environments and can easily access wood that is not properly protected or that is in contact with the ground.

The close proximity of wood to the house can also provide termites and other wood-destroying organisms with a pathway into the structure. If the wood is untreated or improperly maintained, it may become more susceptible to damage. Proper precautions, such as ensuring proper drainage, using treated wood, and maintaining a separation between wood and soil, are crucial to minimize the chances of infestation.

The other options do not address the risks associated with wood in direct contact with the house. Preserving or painting wood may provide some protection, but without addressing the issue of direct contact with soil and moisture, those measures alone are insufficient to mitigate the risk of infestation effectively.
