What bores holes in maple trees?
Certain species of beetles, weevils, worms, caterpillars and others are all known to cause boring damage to trees. Metallic wood borers, longhorned beetles, carpenterworms and horntails are the specific insects likely to attack maples of all varieties.
What causes holes in maple trees?
Common causes of holes in trees include wood boring insects and birds. In the case of insects, it is usually the larval stage that feeds within the tree while the adults feed on leaves or other external tissues. In spite of this, it is most often the adult stage that created holes in the bark.
What causes a hole at the base of a tree?
A tree hollow is a cavity in a living tree. Tree holes can be caused when an injury to the tree, such as breakage of a limb, creates an opening through the bark and exposes the sapwood. The sapwood is attacked by fungi and bacteria, which form a cavity in the bole of the tree.
What do small holes in trees mean?
Many tiny holes in tree trunks and branches may indicate bark beetles; larger open tunnels filled with sawdust-like boring dust (frass) indicate clearwing moths; flatheaded or roundheaded borers leave wet spots and dark stains and D-or 0-shaped emergence holes.
How do you treat Maple gall mites?
Because the mites overwinter on the host trees, dormant oil sprays can be quite effective (although oil sprays should not be used on sugar maple, Japanese maple and other oil-sensitive trees such as birch, hickory and walnut because of phytotoxicity problems). These should be applied prior to bud break.
How do you get rid of borers in trees?
Clear away frass to expose tunnels and stab grubs with a piece of wire. Prune off infested branches where practical. You need to make sure the borer larva is inside what you are pruning off.
What causes a hole in the base of a maple tree?
It’s possible the wound originated with chewing from a vole or rabbit, but I’ll bet your maple “resident” is just taking advantage of a warm shelter and moving bedding material into it for winter. More often, wounds low on trees are caused by mowers or other heavy objects bumping into them or by frost cracks.
What to do if a tree has a hole at the base?
Most of the time, anything you do would be counter-productive. Trees are pretty good at callusing over wounds and protecting themselves without any help from well-meaning people with tar brushes and cement trowels. The problem is when decay occurs and outpaces the tree’s ability to defend itself.
What to do if your maple tree has anthracnose?
Once a tree is infected, the disease survive the winter in infected branches and then spread when the wind carries its spores to surrounding trees. Anthracnose can be controlled by removing dead leaves from the base of your trees in the fall.
How big is the hole in a tree?
There is a large hole in it — maybe 2 feet tall and 1.5 feet wide, and a large hollow within the tree. The first thing I noticed was that the hollow went lower than the surface hole, so it would hold water when it rained.

What should I do if my maple tree is dying?
Fertilizer – First gather a sample of soil from an area near the base of the tree to check its pH level. The best level should range from 5.5 to 7.3. If it is less than that it is dying from lack of nutrition. Get the pH level back to the appropriate range.
