Common nail beetle

Small woodworm
Anobium punctatum

Very harmful! Probably the most widespread and most dangerous wood pest in Europe. It primarily infests dry and processed wood, mass reproduction occurs in roof trusses, in dry, processed (older) softwood and hardwood in intermediate structures, beams, furniture and stairs. Infested wood looks as if it has been shot with fine shot, the flight holes of the adult insects are Ø1-2 mm. The wood is completely decomposed and pulverized by the larvae. Infestation can be recognized by loose drill dust on or in front of the drill holes.
