The main deciding factor of this tarantula living area is the substrate, as a burrower it needs to well burrow, and its believed this tarantula is widespread across Montserrat.

This zoo managed to breed this tarantula in 2016, and they are being observed to understand their lifespan. This tarantula have had some problems with their habitat, as invasive species, development and the volcanic development are major threats to this spider.
