Day Valley's Colony-Elimination Ant Team

Spraying the trail kills foragers but leaves the queen untouched, and can cause the colony to split and relocate.

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.

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

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.
