Best Answer

Bark beetles bore through the bark to eat the tasty nutrients in the inner bark known as the phloem and cambium layers. If they eat all the way around the tree, they will girdle the tree and the tree will die. Girdling cuts the trees food tubes and it will be unable to send nutrients up and down the trunk.
