Crevice Bat Box (NB)

Crevice Bat Box (NB)

  • Designed for small crevice dwelling bats especially pipistrelles.
  • External surfaces black to increase heat absorption.
  • Internal ceramic heat sinks to retain and stabilise box temperature.
  • Grooved landing ladder continues internally.
  • Precision cut FSC certified panels for dry, draught free, long-lasting box.
  • Available in two sizes either double or treble crevice.


Our Crevice Bat Box is designed for those bat species which would naturally roost in crevices and internally has either two or three crevices for the bats to roost within. These crevice bat boxes are especially suitable for both Common Pipistrelles and Soprano Pipistrelles. These two species are the most abundant bats in the UK and most frequently use bat boxes.


The batbox is available as either double crevice or treble crevice, with the treble crevice being 50% larger internally. The treble crevice has an additional crevice to provide greater space for a larger bat roost. The inside temperature of the bat box makes a big difference to the bats, so the crevice bat box has been designed, with ceramic heat sinks and black external colouration, to warm up faster and maintain a more stable internal temperature than other bat houses. Each crevice is designed to "run" at a slightly different temperature, so that the bats can choose the exact temperature they prefer.


Designed taking into account our 12 years’ experience of making bat boxes, with the benefit of customer feedback, the latest scientific thinking and advice from experts on British bats. The key features include:

17mm entrance slot is ideal for bats but deters birds.

Close fitting panels and roof (precision cut by computer controlled equipment) with insulation above crevices to reduce draughts, improve heat retention and keep each crevice at a different temperature.

Internal ceramic heat sinks for improved temperature stability.

Bat ladder at base of box continues inside box to ensure bats find it easy to access and move around within the box.

Easy and safe to erect box on walls or trees - relatively light weight with 2 screw holes for mounting.

 Simple to remove roof (1 screw) for cleaning or inspection where permitted

External surfaces treated with water based non-toxic non-volatile wood treatment.

Manufactured in exterior grade FSC Certified European birch plywood


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.
