The method, detailed in the Journal of Economic Entomology, uses a pleasant-smelling chemical released by forest trees called pinene that reminds western drywood termites of their food.

Using an attractant like pinene eliminates the need to hunt for the termites.

"Even at low concentrations, pinene is good at attracting termites from a distance," Choe said.

"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.

“You’ve got pinene coming in at 2.83 percent, good for memory retention and alertness, and then myrcene, which should help balance out some of the raciness from the limonene. Myrcene is good for your brain’s absorption of metabolizing THC but also has relaxing, sedating qualities.”
