1 or 2 per day.

We had a large scale attack the first day I mowed the lawn this year. Some must have come in on my clothes.

We used Raid bait traps to kill the bugs that may be hidden in walls or underground. The ants will take it back to the nest
and kill their buddies.

Then we followed up with Raid Ant Killer 17 and a few days later there were zero ants.
