The Hunt Begins Control of an ant infestation depends on finding and treating the colony. Different ants have different preferences on where to live. This is why identification is so important. Knowledge of an ant's biology provides clues on where to look. Practicing a few proven field tips can save time in uncovering the source of an infestation.
Most pest ants like to trail under the edge of carpets.
Inspect along the walls under the carpet beside the tack strip. A good place to start is in front of fireplaces and sliding glass doors. When foraging ants are found, try to trail them back to their colony location. When ants are found inside along exterior walls, look for colonies living in the soil beside the foundation. Pull back the vegetation to look for ants.
