Put a small amount of the bait inside a short section of soda straw to create a bait station. If you see lines of ants, place both types of bait stations in the line. Observe to see which station attracts them. Place 20 to 30 bait stations filled with the preferred bait near the areas ants tend to gather and allow them to feed on the bait.
The ants take a few grains of boric acid back to the colony with each trip. Eventually, a worker ant feeds the bait to the queen and kills her. Once the queen dies, the colony no longer produces more ants. Within a few days, the number of ants in the home should begin to decrease.
