This Is How People Used To Block Rat Holes [cDFNgUHJ06k]
Look, people in China used steel nets to block rat holes back in 1980s with whatever they would find at home but over time, it would get rust and the rats would chew through them and get inside again. Then, around 2000, people started using expanding foam. At first, it seemed like the perfect solution but the rats could easily chew through the soft foam as well but people in 2026 use a special wall repair paste that hardens like stone and rats don’t chew through it because they can’t even tell there’s a hole behind it anymore.
