Compared to the number of timbers available, the list of wood species resistant to termites is rather limited and largely composed of tropical timbers. In addition, due to climate change and environmental degradation, together with global trade, a significant global expansion of termites is predicted along with the economic losses due to their activities. Therefore, there is a demand to find products, preventing wood and wood-based materials from termite attack, that will fulfill both biocide regulations and market requirements. The performances of a newly developed plant bio-based product (containing polyphenols) have been evaluated through: (1) laboratory screening tests on cellulose paper against Reticulitermes flavipes, (2) laboratory tests according to the guidelines of EN117 against Coptotermes gestroi and Prorhinotermes canalifrons, and, (3) soil treatment tests against C. gestroi. This work reports the efficacy results obtained using different test methods and termite species, which helps to explain the mode of action of this versatile plant-based product.
