SUBSTANCE: method for protecting wood from technical pests during storage in a stack provides for covering the laid stack with a polyamide mesh impregnated with an insecticidal composition, while the composition is a mixture of compatible insecticide and fungicide with a content of this composition of 2 kg per 1 kg of mesh, and the mesh is used with a mesh size in the range from 20 to 50 mm, selected from the condition of their largest size not exceeding the minimum size of technical pests. The composition is a mechanical mixture of compatible insecticides and fungicides, taken in effective quantities for technical pests, while layer-by-layer distribution of the mixture, formation of foam or sediment is not allowed. The polyamide mesh is impregnated by immersion in an excess amount of the mixture in a sealed container. The composition additionally contains pheromones and antipheromones, selectively selected for the dominant type of technical pests.

EFFECT: proposed method for protecting wood from technical pests during storage in a stack provides an expansion of the arsenal of means for protecting extracted wood, provides effective, reliable and safe protection from both insect pests and mould and wood-staining fungi, reduces the consumption of processing material and the possibility of getting a significant amount of impregnating mixture into the environment.
