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.
