Ant control
Getting rid of an ant trail — and the colony behind it.
The ants you see are a small fraction of the colony, which is why store-bought sprays often scatter them without solving anything. Effective ant control targets the nest and the trail, not just the visible line on the counter.
Carpenter ants are a separate concern, because they tunnel into wood and can signal a moisture problem worth checking.
The trail on a Des Moines counter is not the colony
Ants are already among the common central Iowa calls on this host. The live ant page says the ants you see are a small fraction of the colony, and carpenter ants are a separate wood-and-moisture concern. A referred Des Moines-area provider treats the nest and the trail, not only the line on the counter. This site connects the call; it does not apply the bait.
