I have a battle plan. I bought some of that 1/4" thick PVC plastic lattice. (I think it's PVC, but it's some kind of plastic for sure.) I also got some of the matching grooved edging, that goes around it to give it some stiffness. That stuff is cheap, tough, and easy to work with and cut. Then I got some 1/4" mesh galvanized screen.
Tomorrow early I'll go up and take some measurements. Then I'll build the whole thing, edging, screen and all. I'll use PVC pipe cement and Stainless screws. That stuff will melt anything together. After I'm done, I'll paint it to match, drill some mounting holes. Then go up and install it.
It should look good when I'm done. And the bastards won't be able to get under that eve. I bought the screen because they can fit between the holes in the lattice. I found a nice 8' Aluminum step ladder at Lowe's for just $65.00, so I grabbed it. I don't want to attempt this with that $h!tty little ladder I've got.... The war continues.
