Body: Bark beetles rely on pheromones and terpene signals to coordinate mass attacks on conifer trees. Catnip’s nepetalactone shares structural similarities with some of these compounds — raising the question: could it interfere?

While no direct studies confirm its effect on bark beetles, the idea merits exploration. Field trials with catnip extract or companion planting near vulnerable stands could offer insights. In the long term, genetic engineering of spruce trees to express nepetalactone might become a frontier in forest protection.

Plant chemistry offers promising pathways to disrupt bark beetle infestations and protect forest ecosystems. By connecting this research to broader sustainability and climate adaptation efforts, we can highlight how natural defenses may complement technological solutions.
