Keep the vermin out
A vermin shield or seal is a protective barrier installed at the base of shed wall cladding to prevent rodents, insects, and other vermin from entering the shed. This shield typically fits between the shed cladding and the concrete slab, sealing gaps where pests could enter while also helping to block wind, rain, and debris. Vermin shields are installed during shed construction to maximize effectiveness, but retrofit options are available for existing sheds to improve pest protection and durability.
