With special care it must be applied in dark and warm places, in basements and warehouses. Also in areas around plumbing, heating and ventilation pipes, under cupboards and other bulky objects. Repeat the application only when live insects start to appear again.
20-50 g/m2 depending on the intensity of the infestation. Dust the parts of the surfaces until a thin surface layer of dust is created, especially the corners or crevices and where insects usually pass or hide. The areas where insects pass, hide or breed must be properly identified so that increase the effectiveness of the fight.
