Anti-woodworm treatment for fumigation Both anti-worm systems of which we have already spoken, are effective interventions only if we are lucky enough to quickly notice the presence of woodworms and therefore in the presence of a visible hole.

Once the treatment is complete, we must remove the cellophane and clean everything thoroughly before proceeding with the restoration of the artifact.
