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

Yes — fire ant mounds often need direct mound treatment in addition to broadcast baiting, since mounds can be scattered across a large area.

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.
