Scientists at UC Riverside found a way to kill western drywood termites by using a pleasant-smelling compound called pinene. This trick increased the effectiveness of insecticide from 70% to over 95%!.

This new method is cheaper and more effective than traditional treatments. In experiments, researchers used pinene to lure termites towards treated wood. The result was a significant jump in effectiveness - from about 70% mortality with insecticide alone to over 95% when pinene was added.

Western drywood termites are native to North America and play an important role in nature by helping break down dead wood. However, they can become a serious problem when they move into houses. They don't distinguish between natural wood and structural lumber, which is why they're a persistent concern in places like California and Florida.

The traditional treatment for drywood termites is fumigation, where a home is sealed under a tent and filled with gas to kill the insects. While this approach has been widely used, it has drawbacks. The chemical used in fumigation, sulfuryl fluoride, is toxic to humans and also acts as a greenhouse gas. It's also costly and doesn't stop a home from becoming reinfested later.

Another option is localized injection, where pest control workers drill into infested wood and inject insecticide directly inside. This method targets a smaller area and can use fewer chemicals, making it less expensive and more effective in the long run.

Why It Matters

This new trick to kill termites matters because it could help reduce the cost and environmental impact of termite treatments. As India's population grows, so does the need for innovative solutions to common problems like pest control.
