First, its knitted construction often catches rodents’ teeth and makes it hard for them to chew through or remove. Second, copper mesh never rusts. And it will not leave rust stains on brick or wood. It excludes rats, mice, birds and insects, and is easy to cut with scissors.
Once tightly packed in a hole, crack or gap, the copper mesh can not be pulled out. This is because copper wool has a special interlocked structure. You can tack it, staple it or glue it to any openings. The copper is construction grade quality. The roll is 100 feet long and about five inches wide.
