Contact spray disrupts the trail temporarily but rarely reaches the nest.

Look for bigger ants and fine wood-shaving debris — a byproduct of their excavation.

Bait transfers through the colony over one to two weeks, so expect a gradual decline rather than an instant stop.

Yes — mounds often need direct treatment plus broadcast baiting, since a colony can have multiple mounds scattered widely.

Colony elimination clears the current infestation; a seasonal perimeter program helps prevent a new one establishing. Seasonal exterior treatment is the most reliable way to prevent a fresh colony from moving in after the current one clears.

Bait sits in enclosed stations or protected areas specifically to limit pet and child access. It also helps to keep mulch pulled back from the foundation a few inches, since that alone reduces bridge points significantly.
