Borers are organisms that create boreholes or tunnels in solid substrates such as wood, plant tissue, shells, or rock. They occur in both terrestrial and aquatic environments and contribute to decomposition and nutrient cycling in ecosystems. At the same time, many borers can cause damage when they invade living trees, lumber, structures, or submerged timbers, making them notable as pests in forestry, construction, and maritime settings.

In terrestrial environments, wood-boring insects are among the most familiar borers. Larvae of beetles such as longhorn beetles (Cerambycidae), powderpost beetles (Lyctidae), and various bark beetles tunnel through wood, weakening structures and reducing commercial timber value. Termites also bore into wood, creating extensive galleries. In marine environments, shipworms (family Teredinidae) are renowned for boring into submerged wood, including docks, piers, and hulls. Other marine borers include certain bivalves and polychaete worms that drill into shells or calcareous substrates.

Boring mechanisms vary by group. Many insects and mollusks rely on specialized mouthparts to rasp or cut through material, while some species secrete enzymes or acids to facilitate tunneling. Larval stages are typically the primary boring workers, often adapted for dispersal and colonization of new substrates through free-swimming or crawling larvae.

Management and prevention focus on reducing vulnerability and interrupting life cycles. In buildings, moisture control, proper sealing, and wood treatments help prevent infestation, complemented by physical barriers and timely remediation. In marine settings, protective coatings, preservatives, regular maintenance, and careful selection of durable timbers reduce long-term damage.
