Review on 🔧 Haierc Copper Mesh DIY Pure Copper Hole Filler: Effective 100% Copper Roll - 5" X 50FT by Caleb Olsen

(now April 2021) Purchased April 2019 to patch drainage holes in the bricks around my house. The ones put there by a professional exterminator a few years ago oxidized to a green color (just like copper) and there weren't a pair. I pulled out all the old ones and replaced them with this copper material. Some time passed, but last fall the copper color finally faded/oxidized to dark grey. If this material was 100% copper, it should have oxidized to a green color like the material previously applied by a professional exterminator. I recently heard rats in the attic and checked the house. With most still in place, a few pieces of this material were pulled out of the drain holes and the rats climbed in. This also happened with the copper material added by the fighters, so this material was no worse than what the pros used. I'm just not happy that this stuff (at least what I got) doesn't look 100% copper.
