An ant mound of loose dark soil built up in the grass along the edge of a concrete sidewalk in a McKinney lawn, with scattered dry leaves nearby.

This photo from a McKinney yard shows an ant mound of fine, loose soil pushed up through the grass right against the sidewalk. Ants often build along concrete edges because the slab holds warmth and shelters the colony, and October weather keeps them active. Our tech documented the mound during the visit so the homeowner could see exactly where the activity was coming from.
