Copper Mesh Roll, Sturdy Pure Copper Stuff-fit Wire Mesh for Gap Copper Blocker Fill Fabric 4" x 40"

We had a mouse invasion this year - I ended up with 26 5-gallon buckets - mouse habitats -- until the snow in Alaska melted enough for us to re-home them back to nature (we found a good spot). We put one mouse in each bucket, but I ended up with a few Moms who came pregnant. Mouse pups are extremely cute (ours would stop and look up when I checked them with a flash light - or freeze in place when they were playing like dog puppies. But who wants to share a home with mice? We caught them in live animal traps we bought on Amazon. And then I hired a pest control guy to plug all the mouse holes that went outside and upstairs. He used this copper mesh because it doesn't ionize and wear out like steel wool will when you push it against pipes. It's more flexible than steel wool and it doesn't drop little pieces from it too. Mess free Mesh.

I was able to get all the drain holes on my house with this product

The high-quality copper mesh is easy to cut to the required size, and it is very good. It blends the gap well, without any problems, and remains firm.We use this product to prevent insects from entering small brick holes. It is very flexible and easy to use. It may not be as thick/strong as some other brands, but as far as we use it, it is very suitable and the price is reasonable.

I put this around the trunk of my orange tree with zip tires and haven't seen snails on the tree since. It is very flexible.

I'm using it to stuff in cracks to mice stay out. Not sure if it's gonna work. I went to stretch it and it started to break apart. It's pretty soft. See copper in back of cabinet in the image.
