Holes in the tree trunk can have a serious or harmless background. Whether countermeasures are necessary depends on the armored, winged or furry perpetrator. Read useful tips about which animals cause holes in tree trunks here.
Which animal causes holes in the tree trunk?
Holes in tree trunks can be caused by insects such as beetles and hymenoptera or small vertebrates such as woodpeckers, owls and bats. They serve as a breeding place, sleeping cave or pantry. Although woodpecker holes do not harm the tree, fungal infections and rot can occur from the holes.
Which animal makes holes in a tree trunk?
Insectsandsmall vertebrates cause holes in the tree trunk as a breeding place, sleeping cave or pantry. The resulting hole sizes range from 1 cm to 10 cm and more. The following list names common animals that drill, gnaw or hammer small and large holes in the trunk wood:
- Beetles: longhorn beetles, bark beetles, jewel beetles.
- Butterflies: willow borer, wood borer, blue screen.
- Hymenoptera: giant wood wasp, carpenter bee, hornet.
- Vertebrates: woodpecker, owl, bat, dormouse, squirrel, pine marten.
What damage can holes in the tree trunk cause?
Fungal infections and rot are the most common damage caused by holes in the tree trunk. Drill holes are ideal entry points for fungal spores and bacteria because they often extend far into the trunk. An unstoppabledecomposition process is getting underway. If insatiable pests eat through the wood at the same time, the affected tree is doomed. Unfortunately, the damage is barely visible from the outside. There is a high risk that the tree will collapse uncontrollably during a storm or snow pressure.
Can woodpecker holes in the trunk destroy the tree?
If the woodpecker hammers a nesting hole into the trunk, the tree will diedoesn't break In advance, woodpeckers specifically look for a tree weakened by disease because rotten wood is easier to reach with their beak edit is. The rot that often occurs in woodpecker holes is therefore not a result of busy carpentry work, but had long since infected the tree.
Tip
Don’t take bark beetle holes lightly
Bark beetle holes in the tree trunk are just the tip of the iceberg. An explosive proliferation is raging beneath the bark. A single female printer produces up to three generations of up to 100,000 offspring. The larvae eat their way voraciously through the wood, hollowing out the trunk and endangering its stability. Because the pests are excellently protected from insecticides, only felling trees stops the vicious circle.
