Here is a substantially reworded, engagement-optimized version for a general audience, with the original facts preserved and a light update in context. Scientists at UC Riverside have identified a cheaper, highly effective way to kill western drywood termites by drawing them toward insecticide instead of trying to track down every hiding place. In experiments tied to a study in the Journal of Economic Entomology , the team used pinene, a pleasant-smelling compound released by forest trees, to make the insects move toward treated wood. The result was a major jump in effectiveness, from about 70% mortality with insecticide alone to more than 95% when pinene was added. "We saw significant differences in the death rates using insecticide alone versus the insecticide plus pinene," said UCR entomologist Dong-Hwan Choe, who led the discovery. "Without pinene, we got about 70% mortality.…
