QueenBird Copper Mesh with Packing Tool - 5 X 30 Feet - Blocker for Hole - DIY Hole Filler, Copper Fill Fabric, Ideal for Distilling, Pure 100% Copper Roll

Used to prevent mice from entering. I put in holes, vents and under stove. Doubled it up in some places it’s sorta thing.

Copper mesh. Exactly what I needed. Im not a metallurgist so I cant tell if its 100% pure copper or not but it appears to be.

Easy to use and strong

Im a little nervous about this product but it didnt cost much. I used this in a closet space that had a rat/mouse problem. I used it in combination with great stuff spray foam. If you tried to stretch this product out (use less to cover more space) id be hesitant. Its very thin, when you cut it it leaves little fragments of copper, doesnt seem to fall apart but it also doesnt seem very strong, hope it does what its supposed to considering once the wall is put back together I wont be able to go back in and check it. If you roll it up and stuff it plugs holes really well though.

Worked as advertised...good quality, pure copper and fairly easy to install.

Using this product to block potential pest holes in my camper. Works very well and easy to use.

I bought this because there are some spaces in between my windows and doors that I havent been able to cover up and i dont want any lizards getting into my house. So far, it has worked perfectly. I hope its because of this :)

This material was easy to use for cutting and slipping into the weep holes on our brick home … So far the mice population has not been able to penetrate the barriers and they still allow the wall to breath as they are intended to do … Wish the builders of homes stepped their game up and installed this material in the first place … We would have never had to hear the tapping of little mice running through our attic … So far so good. Material cuts easy with scissors. I cut into 4” pieces and rolled the material then simply shoved it into the weep holes with my finger then used the little stick they send to shove it in about a 1/2”. Good Luck!

My atypical application involved using the copper mesh as a heat transfer medium between two flat surfaces. The springy copper mesh made good thermal contact with, and a path between, a heat source and a heat sink.
