How do wood-plastic composite (WPC) sculptures resist insect damage compared to traditional wood?

Wood-plastic composite (WPC) sculptures possess inherent insect resistance that traditional wood cannot match. Unlike natural wood that contains cellulose - a primary food source for termites and wood-boring insects - WPC materials combine wood fibers with plastic polymers to create an inhospitable environment for pests. The plastic matrix encapsulates the wood particles, preventing insects from detecting or accessing the nutritional components they seek. Additionally, manufacturers incorporate insecticides and repellents directly into the composite material during production, creating a permanent barrier against infestation. This built-in protection eliminates the need for toxic chemical treatments that traditional wood sculptures require periodically. The non-porous surface of WPC further deters insects by denying them the moisture and organic decay they need to thrive. While traditional wood suffers from structural compromise due to insect tunneling and larval feeding, WPC maintains its integrity indefinitely. This resistance extends to fungal decay and moisture damage, which often attract secondary insect infestations in natural wood. The result is outdoor artwork that remains structurally sound and visually intact for decades without insect-related deterioration.
