Amherst's Colony-Elimination Ant Team

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.

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

We typically combine spot mound treatment with a wider bait application.

Colony elimination clears the current infestation; a seasonal perimeter program helps prevent a new one establishing. 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.
