Bats are threatened by the trend of sealing our buildings, as they have historically enjoyed nesting places and roosts under our snug eaves or in warm attics. Bat populations are particularly threatened by the prevalence of non-woven synthetic roofing membranes, in which they sadly become trapped. Roosting aids are a safe alternative for bats. A well-constructed and properly located bat roost may attract bats if they live in or pass through your general area. Bats need and seek a roost in a sunny spot – a warm place in which to raise their young, that allows them to decrease their metabolic rate during roosting.
We recommend placing the roost in full sun, on a standard 10 cm x 10 cm softwood post with a top shaped according to the habi-sabi template. The roost spaces are created between the outer body of the roost and the shaped top section of the softwood post, creating the snug space needed by crevice-roosting bat species including the Brand’s bat, whiskered bat and UK pipistrelle species.
The optimal temperature range inside the roost is 29 – 40 °C (85 -104 °F). Please ensure the area around the entrance of the roost is kept clear of obstructions for a minimum of 6 metres. For further information please refer to the Bat Conservation Trust website.
The roost is manufactured from Phonotherm 200 – a rigid, inert, durable and stable insulating board made from post-consumer recycled materials that would otherwise be destined for landfill. The boxes combine physical stability and optimal thermal performance. Manufacturing complies with environmental standard ISO 14001 and the boxes are free from adhesives and formaldehydes, making them safe for wildlife.
The habi-sabi bat roost is provided without the mounting pole however instructions for the supply, size and installation of the pole are provided with purchases. The roost is easy to assemble and fit – it can be built without any fixings, all you need is some sandpaper.
