Wood-destroying organisms are living entities that feed on wood, causing damage to structures and furniture. The most common types include termites, wood-boring beetles, and fungi. These organisms break down cellulose, a key component of wood, leading to structural weaknesses and potential collapse if left untreated. Preventing damage from wood-destroying organisms involves regular inspections and maintenance. Homeowners can protect their properties by using treated wood, sealing cracks, and ensuring proper ventilation to reduce moisture, which attracts these pests. Early detection and intervention are crucial to minimize damage and maintain the integrity of wooden structures.
