The County carries a product called Beetle Block Verbenone, used in spot applications to help prevent beetles from attacking valued trees. Verbenone pouches can be attached to specific high value trees chosen to be protected.
Verbenone is an anti-aggregation pheromone used to prevent attacks on healthy pine trees. It is not a pesticide, but a naturally occurring chemical that mimics a heavily infested tree. Beetles may avoid attacking trees treated with this pheromone.
