There have been many studies on where Punctum minutissimum has its niche.  P.  minutissimum lives in habitats around the world mostly in Holarctic ecozones; which includes North America, Europe, North Africa, and Asia.  The snail is also found in South Africa and the pacific islands (Martin, 2000).  It was found that P. minutissimum likes heavily decaying leaf litter of destructed understory vegetation (Kralka, 1986).  P. minutissimum also likes rock outcrop, upland, and lowland forest sites. (Nekola, 2003).  P. minutissimum can often be found around the polypore and bolete fungi (see figure to left). This little gastropod will settle anywhere that has fallen decaying leaf litter in mild to cool climates.
