Winona, MN's Colony-Elimination Ant Specialists

Spraying the visible trail kills foragers but leaves the colony and queen untouched, and often causes the colony to split and relocate, making the problem worse.

Look for larger ants and fine wood-shaving debris — carpenter ants excavate wood and leave frass behind as a byproduct.

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

Fire ant colonies can have multiple mounds, so we typically combine spot mound treatment with a wider bait application.

Bait treatment removes the existing colony, and ongoing perimeter service reduces the odds of a new one moving in.

We place bait in enclosed stations or protected areas specifically to limit pet and child access. We often suggest trimming vegetation that touches the siding directly, since branches and shrubs give ants an easy bridge past any barrier treatment.
