This durable woodcrete bat box has been specifically designed for the mitigation of small summer roosts, fewer than 10 bats, and mating roosts of building-dwelling bat species. The box is fitted with a rear panel, allowing it to be installed on smooth façades and on trees.
Aim of the product
This durable woodcrete bat box has been designed for building-dwelling bat species. As a summer roost and mating roost, the box is specifically suitable for common pipistrelles and Nathusius’ pipistrelles.
Design
The box is fitted with a rear panel, allowing the bat box to be installed on smooth façades and on trees. It is part of Unitura’s new range of external woodcrete boxes, characterised by a modern and functional design.
The sloping roof of the bat box provides drainage, helping to reduce staining on the façade. Because the box is made entirely from woodcrete, it has good thermal buffering properties. The inside also provides plenty of grip for bats, without being excessively sharp or rough.
Position
Install the box on a building or structure at a minimum height of 3 m, but preferably as high as possible. Do not install the box near a window or streetlight. Preferably give the box a sunny position.
Bat boxes are usually discovered most quickly when installed close to an existing bat flight route. Suitable positions for bat boxes include locations just below roof edges.
Installation
The boxes are easy to assemble, using the included screws and instruction card.
The product is related to VMTH1, GZTH1, HMTH1 and HOTH1.

Bats use a network of roosts at different orientations. Therefore, bat boxes are best distributed among as many different orientations and locations as possible. Bats look for roosts along corners and edges. Place bat boxes on buildings as much as possible along eaves and ledges. The basic maxim is that bat boxes should always be placed as high as possible, but at least 3m high. Make sure there is free space under the box. For a more detailed explanation, see Unitura’s Handbook .
The term small bat boxes comes from BIJ12’s knowledge document Common Dwarf Bat. This designation refers to bat boxes suitable for up to 10 bats. Examples of these boxes include the VMT1, the VMT1a, the VMTH1, the VMPM1 and the VMPM1e.
Mitigation projects under the Nature Conservation Act distinguish between permanent and temporary bat boxes. Typically, temporary bat boxes are first provided in the immediate vicinity of a building being demolished or renovated. Bats can then temporarily move to these boxes until permanent bat boxes in the new or renovated building become available. Typically, bat boxes can only be considered “permanent” if they are highly durable (have the same lifespan as a building) and if they are part of the building’s architecture (the boxes should not be easily removed).
Temporary bat boxes are bat boxes intended to serve as temporary places of refuge for bats. Mitigation projects under the Nature Conservation Act distinguish between permanent and temporary bat boxes. Typically, temporary bat boxes are first offered in the immediate vicinity of a building being demolished or renovated. Bats can then temporarily move to these boxes until permanent bat boxes become available.
