This is the house next door, where no people live...
There is a family of squirrels I’ve seen climbing into the attic under the fascia. There is the small round door to the home of est. 5 million red ants. Their wide, low mound is surrounded by a flotilla of cigarette butts. At least two things are possible: people have, consciously or unconsciously, been throwing cigarette butts on the anthill and the ants have moved them away because, unlike people, 100 percent of ants can tell cigarettes are slow poison; OR ants have been collecting the butts and stacking them around their hill, like a city wall. I will position my butts accordingly and watch for what the ants do.
