Ants are present in the house. Trails of ants may crawl on floors, walls, baseboards, and counters and in cupboards. Ants generally cause the most trouble in the kitchen or pantry.
Most ants are strongly attracted to sweets, starches, fats, and grains, and they invade households in order to carry these foods back to their nests. So be sure to store food in sealed containers, and keep kitchens and pantries free of leftovers and exposed foods, such as honey.
