Sure, ants are mostly harmless, but they’re also persistent little house guests who don’t respect boundaries. They don’t care that you just mopped the floor; they see a sugar spill from yesterday and think, “Perfect, a five-star buffet!”
Beyond the ick factor, ants can actually contaminate your food simply by walking on it. They’ve been trekking through unknown territories—think under the fridge or behind the trash can—before they marched across your bread loaf.
Plus, letting them stay sends a signal to the whole ant colony: “Vacancy! Free snacks and cozy wall cracks!” A few scouts today can mean a hundred residents tomorrow, so a little effort now saves you a lot of annoyance later.
