Underground nest are usually built in dry and sunny sand habitats with scarce vegetation. It is often found together with the ant Lasius psammophilus on sand-dunes. Also occurs in human-constructed open habitats such as river dams, on seaside beaches and occurs up to 1800–2500 m in the mountains.

GBIF citizen-science records
It is estimated from how often the Formica cinerea is recorded against all the insects logged in Berlin (45 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
