This is primarily made from farm waste which is gathered from farms across the UK and processed into sheets from which we manufacture the outer shell of our Eco Kent Bat Box. The wooden interior of the box is constructed from UK grown spruce. This is sustainably harvested and processed on a small plantation and sawmill less than 10 miles from our workshop, keeping the transport miles to a minimum.Bat boxes can be mounted on both buildings and trees. Try to position your box as high as possible in a sheltered sunny place. Ideally, several boxes should be put up facing in different directions to provide a range of conditions. Bats need time to find and explore new homes, and it may be several years before boxes have residents – be patient! Droppings on the landing area, stains around the lower parts of the box and chittering noises from inside on warm afternoons and evenings are signs of occupation.Features:Based on the proven and popular Kent bat box design, but with an additional weatherproof outer shell.Ideal for crevice roosting species such as common and soprano pipistrelles.100% recycled plastic shell protects the wood creating a much longer lasting box.Wooden interior made from spruce, rough-sawn to provide good grip for the bats; sustainably grown less than 10 miles from our workshop.Self-cleaning, maintenance free box.Specifications:Materials: Recycled LDPE plastic outer; certified, UK harvested rough sawn spruce interiorConstruction: Outer recycled plastic panels fitted together using integral tabbing system.
