Biological techniques and tools should be preferred to prevent forest damage and to control its spread. The use of non-biological plant protection products on forest land is only allowed in justified cases.

Description of the action

Pheromone plugs can be placed in the forest to reduce damage to the bark beetle. Place the pheromone traps at least 15-20 m away from the middle and older spruces to prevent worm damage. The spruce bark beetle starts its flight in spring when the birches start to leaf out and the second flight starts in mid-July. Therefore, put pheromone traps in the forest with the arrival of warm weather in spring (around mid-April) and after Midsummer. Clean pheromone traps of dead and trapped wolverines once a week (the smell of dead wolverines is more of a deterrent).

Why?

The use of pheromone plugs is a preventive way to keep bark beetles away from middle-aged and older spruce trees, but it is not a very effective way. The use of pheromone traps provides information on the abundance of spruce bark beetles and can then be used to trap trees if necessary.
