Wood-boring beetles treatment

Updated February 21, 2017

Both trees and wooden structures can fall prey to a number of small creatures. Among these creatures are wood-boring beetles and their larvae, which consume wood as well as lay eggs in it. Although there are many types of wood-boring beetles, treatments are usually similar.

The Facts

Trees that have been attacked by wood-boring beetles will show a variety of symptoms. The most obvious are the holes and worm tracks left behind by the insects as they eat. Serious infestations could cause damage to the vegetation, especially in the crown of the tree, and dead wood.


There is a wide variety of wood-boring beetles, each with its own preferences and characteristics. All beetles, however, eat wood and produce larvae that eat wood. Beetles can prey on both soft and hard wood, and can easily spread from trees to the wood of houses and barns.


All wood-boring beetle infestations can be treated with pesticides. Armour-Guard and Shell-Guard are commonly available in lawn and garden shops and do an efficient job of killing beetles. These substances are spread over infected wood and poison the beetles.


Armour-Guard and Shell-Guard can both act as preventatives for wood-boring beetles by making the wood inedible. Natural preventatives include beneficial insects like ladybirds and lacewing moths, which eat beetle larvae, and other beetle-eating creatures such as lizards and birds.


Although the tunnelled areas of a tree cannot be repaired, it's a good idea to prune away sections of the tree that have been damaged. Insects like beetles are more likely to attack weakened trees, and repairing the damaged area takes time and energy that the tree should put into growing.
