WDO or "Wood-Destroying Organism" refers to any type of insect, fungus or bacteria that can damage or destroy wood structures. There are several synonyms for WDO including wood rot, termite infestation, dry rot, damp rot, and wood decay. It is important to identify and address any signs of WDO activity as it can lead to extensive and expensive damage to homes, businesses and properties. Regular inspections, maintenance, and treatment can help prevent and mitigate the risks associated with WDOs. If left untreated, WDOs can compromise the structural integrity of buildings and cause significant property damage.
