Fortunately, ants leave plenty of warning signs that they are nesting in your plants. If you see a recurring line of ants and are worried about your garden, plants or them entering your home, then look out for these common signs (which should help with potted plant nesting or garden nesting concerns):
Visible Ant Trails: Ants often create visible trails along plant stems and leaves as they move between their nests and food sources.
Presence of Honeydew-Producing Insects: Look for aphids or scale insects on your plants, as these pests attract ants due to the sweet honeydew they produce.
Plant Damage: Ants can cause indirect damage to plants by disturbing soil around roots or excavating nests in plant pots, potentially harming plant health.
