A great deal of insects is able to survive off of feeding on trees. Here they will also use the bark, trunks, and shade of trees to disguise themselves in a new home. Most infestations are of beetles, moths, bees, and wasps. In some cases termites can invade your tree as well. These various pests are drawn to the sick and weak state of a tree. Whether it’s through disease, age, damage, or lack of nutrition these pests will find their way inside.
Typically these infestations will not be discovered until there is noticeable damage on the outside of the trees trunk. You can find these infestations however, by searching for the clues and symptoms they leave behind. Many of them leave droppings that resemble a wood colored dust or powder. Many insects will dig tunnels from the roots of the tree, through the bark, and into the trunk, leading up to the trees branches. Here they are able to intercept the water being transported in the form of nutrients throughout the tree.
This is how trees are broken down by insects, they hijack the nutrients the tree needs to survive and trigger its breakdown. Here trees will become more inclined to fall prey to disease as well.
