What are the signs of a tree borer infestation?
Tunnel holes: One of the telltale signs of a tree borer infestation is the holes created from borer tunneling. Depending on the species of borer, these tunnels may have round, semicircular, or oval shapes.

The tunnels and exit holes of roundhead borers are oval to round. The life cycle of roundhead borers is similar to flathead borers, and trees exhibit the same signs of infestation. Serious infestations of roundhead borers can kill trees, but these beetles usually only attack damaged or unhealthy trees.

Can you save a tree with borers?
Once borers have infested a tree, they can be difficult to control. Insecticidal sprays can be successful only if they are applied to the tree when the adult borers are active and laying eggs. Consequently, the proper timing of insecticide sprays is crucial for effective chemical control of borers.

Systemic insecticides applied via trunk injection, basal bark sprays, or as a soil drench are effective against flatheaded borers and they may be the only practical method for treating tall trees.
Why are squirrels eating my cedar tree?
There are several theories as to why they strip the trees of bark. Perhaps they eat the underlying cambium of the tree, which would contain the tree sap. A second theory is that they simply like using the tree bark in their nests. Cedar, of course, would be fragrant, and might be insect-repellent.

What are metallic woodboring beetles?
Metallic woodboring beetles (Buprestidae family) are flathead borers. The beetles are recognizable by their shiny, metallic-colored shell in shades of copper, blue, bronze and green. Female beetles lay eggs in the cracks and crevices of bark. The eggs hatch into grub-like larvae that tunnel through the inner bark and sapwood. The larvae have wide, flat bodies behind their heads, and their tunnels are typically oval shaped. The larvae pupate into mature beetles that chew their way out of the tree, leaving oval or “D” shaped holes in the tree. Infested trees may have one or more dead branches, sections of bark that appear wet or greasy-looking, or areas where the bark has fallen from the tree. You may also see areas of sawdust or frass on the tree bark or at the base of the tree. Flathead borers can kill young, stressed or weak trees.
How do bark beetles affect trees?
They may kill twig ends, weaken branches or even kill the entire tree. Bark beetles can also spread Dutch elm disease between trees.

The most obvious signs of tree borer insects are the tiny holes they cut into trunks, branches, and stems.
What are Tree Borers?
Tree borers are a group of insects that lay their eggs on or inside of trees, where the young larvae eat their way through living tissues. These miscreants can be either beetles or clearwing moths, but the end result is the same. Tree borer insects cause affected parts of trees to slowly weaken as their chewing severs vital transport tissues. Over time, they may girdle trees or weaken branches to the point that they break under pressure.
What insecticides can be used on borers?
All woody surfaces must be covered for these materials to work. Imidacloprid and dinotefuran, systemic insecticides, can control borers that remain close to the bark layer of the tree, but should not be applied without identifying the pest inside your tree first.
How do you know if you have tree borers?
The most obvious signs of tree borer insects are the tiny holes they cut into trunks, branches, and stems. These holes may be perfectly round or slightly oblong, sometimes a sawdust-like material, called frass, falls on branches below these holes or forms a long cylinder as tree borer insects excavate tunnels.

What does it mean when a stone fruit tree oozes sap?
Oozing sap (gummosis): A stone fruit tree will have gummosis, sap oozing from its wounds, during a borer infestation. If borers dig into sap-producing parts of the wood, the sap flows out of the tunnel. You may also see frass in the oozing sap.
How to handle wood borer infestation?

What happens when a tree is attacked by a borer?
When a borer attacks a vigorously growing conifer (like pine), the tree can physically pitch the borer out of the trunk in a flow of sap. Under full sun conditions, healthy trees have enough energy reserves to produce poisons that can kill many of the infectious diseases that can be spread by borers.
What do borers do in the bark?
Borers that feed in the trunk produce a random pattern of holes in the bark (Figure 1). They can be distinguished from those produced by feeding woodpeckers and sapsuckers which make holes in a straight line (Figure 2).
What are sawyer beetles?
Pine sawyer beetles (Figure 4) are often reported on white and Scotch pine. Infested trees have holes about 3/8” wide that produce a tremendous amount of finely shredded wood shavings and brown grainy excrement. Peeling back the bark of affected trees during the spring and fall reveals 3/4” long white round-headed borers with strong brown mandibles. In July, it is actually possible to hear the grubs chewing beneath the bark. The first beetles that attack these trees can carry a roundworm called the "pine wilt nematode" which can clog the tree's circulatory system so fast that their needles yellow and wilt before they turn brown. As with bark beetles and blue-stain fungi, healthy plants are better able to withstand some attacks. Pine sawyer beetles winter as larvae and emerge as adults from mid-May through August.
How can borers be reduced?
Injury from borers can be reduced by helping trees protect themselves, recognizing and managing early signs of borer injury, and sanitation - the removal of borer infested trees from the landscape .
