The crevice box features two internal crevices 22mm wide, ideal for common pipistrelle and soprano pipistrelle bats. The cavity box is ideal for cavity roosting bats with a single internal cavity 60mm wide with rough walls and roof for bats to hang from.The box requires no maintenance as it is designed with angled baffles which mean droppings simply fall out of the entrance slot. The box is available with either brick, green or black coloured front panels to fit tastefully into your building.We suggest these built in bat boxes should be positioned 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 and chittering noises from inside on warm afternoons and evenings are signs of occupation.Features:A built-in bat box designed to provide a permanent bat roost in buildings.Sized to replace six standard UK bricks without obstructing the cavity.Equally suited to fitting in timber cladding, random stone and external insulation.Self-cleaning design requires no maintenance.Recycled plastic weatherproof shell with internal wooden roost chamber.Choice of internal roost chamber for crevice or cavity roosting bats.Choice of brick, green or black coloured front panels.Specifications:Materials: Recycled LDPE plastic outer with internal OSB roost chamberConstruction: Outer panels welded, internal chamber formed from stapled panelsFinish: Black carcass with brick coloured front panelsEntrance: 17mm wide slot.Internal: Crevice Roost Chamber: 2 crevices 22mm wide; Cavity Roost Chamber: Open roost chamber 60mm wideAccess: No access once fitted, self cleaning, droppings fall out of entrance slotFixing: Held in brickwork by mortar/sealantDimensions and WeightDimensions: Overall height: 440mm, Overall width: 215mm, Overall Depth: 105mm.3.0kg
