What is the Bark Beetle's Diet?

Bark beetles consume tree bark.

What is the Bark Beetle's Reproductive Cycle?

Male and females bark beetles bore tunnels through bark, and the female bark beetle lays eggs in the side niches along the gallery. The larvae will then tunnel its way towards the surface, packing their tunnels tightly with frass. As they molt, the tunnel size increases. They will pupate near the surface and then the adult bark beetle will emerge.

Where do Bark Beetles Live?

Bark beetles are often brought into structures with unseasoned firewood. They emerge through exit holes and are drawn toward light. Bark beetles can create problems for log cabins and park shelters when the bark is left on the logs. They most commonly infest bark-covered wood.
