Zwille climbing stop is a transparent and stable film that is wrapped around the tree and fixed in place with the double-sided adhesive strip. It protects young birds from nest robbers and acts as an obstacle when climbing up. Nest predators such as stone martens, raccoons and cats are irritated by the foil and avoid climbing up any further. We recommend installing the film, especially during the bird breeding season.
When they reach the top, they sit down on the roof of the nesting box and try to reach the nestlings with their paws from above through the flight hole. If this does not work, they drum around on the roof until the parent bird flies out startled. At that moment they grab and kill the parent bird.
The nestlings that starve to death are left behind. It is estimated that millions of songbirds fall victim to bird predators every year.
A completely different problem is faced by homeowners with unwanted rooftop residents.
Raccoons and martens like to climb up house walls and gutters. Both use trees and gutter downpipes to get along the house wall and over the roof into the interior of the house.
Video-Assembly instruction
Zwille climbing stop is recommended for all trees that have a nesting box. The foil is 57-60cm high and 170cm long or wide. It can be used to wrap trees with a maximum circumference of 164 cm.
Attach the Climbing Stop to the tree from a minimum height of 130cm. Climbing up to the nesting box is interrupted. Adjoining trees, which allow nest robbers to climb over them, should also be equipped with a slingshot climbing stop.
