The spruce bark beetle is the insect that does the most damage to our spruce forests.
2.5 million cubic meters of forest infested in southern Sweden. The dry summer of 2018 led to major attacks.
Infestations of spruce bark beetles can be identified throughout the year, but it is especially important to keep an eye out for fresh damage from May to August. The Swedish Forest Agency recommends drones for help in the search for spruce bark borer infestations.
Identifies trees with rust-red tops or with flaked bark for signs of infestation.
