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

They're larger than most household ants, often black or black-and-red, and you may notice small wood shavings near baseboards.

Colony elimination via bait typically takes one to two weeks as it spreads through the nest.

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

Bait removes the existing colony, and ongoing perimeter service reduces the odds of a repeat. A recurring perimeter visit every season is usually enough to keep new colonies from establishing near the foundation.

We place bait away from where pets typically roam, and can discuss specific concerns at scheduling. It also helps to keep mulch pulled back from the foundation a few inches, since that alone reduces bridge points significantly.
