Design Concept

The cavity-chambered rocket roost combines two roosting strategies within a single structure.

The upper section incorporates a spacious cavity intended to provide a sheltered clustering area for cavity-roosting species. Below this, the proven double-chamber rocket box design provides additional roosting space and a range of thermal conditions.

The design allows bats to move freely between the cavity and crevice-style chambers, enabling individuals to select preferred conditions throughout the day and across changing seasons.

Typical Species

The cavity-chambered design has been developed primarily for:

• Brown Long-eared Bat (Plecotus auritus)
• Leisler’s Bat (Nyctalus leisleri)
• Daubenton’s Bat (Myotis daubentonii)

The lower chamber system may also provide secondary roosting opportunities for other species where local conditions are suitable.
