How do pheromones work? Beetles and other insects communicate using pheromones. Verbenone & MCH replicate the beetle pheromones that tells other beetles the tree is full and that the food supply is insufficient for additional beetles. Arriving beetles receive the ‘message’ that they should look elsewhere for a suitable host.
How safe are pheromones? MCH and Verbenone are environmentally safe and non-toxic to humans, pets, birds and even the beetles themselves. Always follow the instructions provided.
