The rout and fill method is commonly employed to control the growth of dry rot because it addresses the structural integrity of the wood affected by the rot. This method involves removing the decayed wood by routing out the damaged areas and then filling those voids with a suitable filler, often a wood epoxy or similar material. This approach not only eliminates the existing dry rot but also helps to restore the strength and stability of the wood structure.

Wetting the affected area could potentially exacerbate the problem since dry rot thrives in moist environments. Applying sealant may limit moisture entry but does not directly resolve existing rot issues, and using pesticides is not effective against fungi such as those that cause dry rot, as they are not pests in the typical sense that pesticides target. Therefore, rout and fill is the most effective and commonly used method to control and prevent the progression of dry rot in a structure.
