Almost every morning I am awaken by birds pecking at the metel mesh attic soffit. In my last home the woodpecker brokethrough and I had to put a wood block up to cover the hole, becuase the other birds where stealing my insulation. How do I cover these so that the birds will not peck at the metal grate. This is a 40 year old home and it is just a piece of metal that has holes. I was thinking of putting a cage over it to keep the birds away from it, but I am afraid they would then create a nest. Also where would I get such a thing?
