Wildlife World Stainless Steet Hole Protector 32mm (Round)

Pre-drilled ready-to-fit hole protector 32mm for nest boxes. The purpose of the hole protector is to prevent the wooden nest box entrance hole being enlarged by pecking or gnawing. Unprotected entrance holes on wooden nest boxes are often attacked by squirrels, woodpeckers and even small mammals in an attempt to enter the box for nesting or in some cases to predate on the eggs and fledglings of small birds. This results in damage to the nest box or at worst lost broods. The 32mm hole protector is considered by the RSPB to be a universal size for all small hole nesting species such as blue tits, coal tits, marsh tits and tree sparrows as well as great tits and house sparrow. Fix using the 2 x stainless steel 3mm/12mm screws which are included, to any wooden nest box. Pre-drilled ready-to-fit hole protector 32mm for nest boxes.
