STUF-FIT Copper Mesh is used to stuff it into openings around pipes or other holes and cracks in a structure to keep rats, mice, birds and other wildlife out. Because of the way the mesh is woven, it is very difficult for rodents to chew through it. Stuf-fit works best in holes and cracks around 2 inches in diameter. It is not meant to be used in live trees and if the hole you are inquiring about is larger than 2 inches in diameter the Stuf-Fit would not be effective.
