Conservation and Treatment of Oil Paintings



F. Insect Damage

Beetle larvae, termites, and silverfish can attack the wooden strechers of paintings on canvas.

Paintings must also be protected from roaches and flies, which deposit small acid specks that are nearly impossible to remove from the paint surface and can corrode both paint and varnish.

Treatment

If insect damage is found, the infested painting must be isolated immediatley and fumigated by a professional conservator.
