1.Highquality material: our rodent control devices made of copper mesh are made of pure copper. Each ring is connected to the other, and the doublelayer tubular design is more flexible and stronger, and this copper net is almost impossible to bite through and remove 2.Effective clogging: copper mesh transforms passive catch into active prevention. Our copper mesh is superior to conventional mouse traps and insect traps and is easy to cut, shape and install. It is designed to fill various openings to stop pests, rats, bugs, snails, insects, rodents and other similar animals. 3.Reusability: Copper mesh does not rust like steel wool/braid and leaves no rust marks on bricks or wood; it does not have the potential risk of steel velvet easily catching fire. You can use it to stuff holes of any shape and size and reuse it for a long time. 4.Easy to use: you can cut the length you need with scissors and then insert it into any hole you want to clog. You can easily reinforce it as needed. It is about 6 m and 12.7 cm wide.
