Researchers at the University of California, Riverside have developed a method that significantly increases the effectiveness of a targeted insecticide against western drywood termites. By adding pinene, a natural tree compound, to the insecticide fipronil, termite mortality rose from about 70% to over 95% in experiments. This approach aims to improve localized pest control, potentially offering an alternative to whole-structure fumigation.
Facts First
- Adding pinene to insecticide boosted termite mortality from ~70% to over 95% in lab tests.
- The method targets western drywood termites, a common pest in California, Florida, and parts of Canada and Mexico.
- The insecticide fipronil was injected into wood, a method designed to lower environmental risk.
- Fumigation with sulfuryl fluoride is a common treatment in California but involves sealing an entire home.
- The research was led by UC Riverside entomologist Dong-Hwan Choe, whose lab studies chemical communication in pests.
What Happened
Scientists at the University of California, Riverside (UC Riverside) identified a method to kill western drywood termites more effectively by using pinene to draw them toward insecticide. In experiments, adding pinene... to the insecticide fipronil increased termite mortality from approximately 70% with insecticide alone to more than 95%. The study, led by entomologist Dong-Hwan Choe, was published in the Journal of Economic Entomology.
Why this Matters to You
If you live in an area prone to drywood termites, such as California or Florida, this research could eventually lead to more effective and less invasive pest control options. A more effective targeted treatment might reduce the need for whole-home fumigation, which requires you to vacate your property. The localized injection method used in the study may also lower the chance of insecticide affecting non-target insects in the environment compared to broader applications.
What's Next
The study's findings may guide the development of new pest control strategies that use natural attractants like pinene to improve targeted insecticide treatments. Further research and development will be needed to translate these lab results into practical, commercially available treatments for homeowners.
