Bark beetles are very small, often just a few millimeters long in the adult stage.
Why do trees have holes in their trunks?
Holes can appear in tree trunks after a limb breaks off or the bark sustains injuries that expose the sapwood. This attracts fungi and bacteria that deepens the cavity. While a tree hollow may seem like a detriment to the tree, it’s an important part of the surrounding environment.

Select a product that is water-resistant and designed for large gaps, advises the Centers for Disease Control and Prevention. Follow the package instructions to fill the cavity with the foam.
What animal puts holes in trees?
In forests, tree holes are created either quickly by woodpeckers or more slowly as trees age and begin to decay. Birds like owls, songbirds and parrots, and mammals like flying squirrels and opossums, make homes in the holes of trees because they offer safe environments for sleeping, reproduction and raising young.
Should you fill a tree cavity?
This abrasion allows decay to move into the living wood by injuring the barrier zone formed by the tree to retard further advance of decay. Never use concrete in trees. Cavities do not have to be filled. Spray insulation has been used to keep animals and children out of cavities.

Should I seal a tree wound?
In most cases, it is best to simply let wounds seal on their own. Over millennia, trees have developed effective mechanisms for this. Unlike people or animals, woody plants are unable to heal damaged tissues. Instead, they compartmentalize wounds with layers of cells that prevent damage from spreading any further.
Why is foam coming out of my tree?
Slime flux, also known as foamy canker, alcohol flux and wet wood, is a condition caused by a bacterium in the tree that pushes the sap out of the tree to bleed from the bark and can create staining, dripping and oozing of the fluid to the exterior of the tree.
