Signs of an ant infestation
Ants multiply quickly, so early detection is key. Here are some signs you have an ant infestation:
Visible ant trails
If you see a steady line of ants moving along walls, floors, or countertops, it means they are following scent trails left by other worker ants. This is how they communicate and guide their colony members to food sources.
Some species, like pavement ants, odorous house ants, and Argentine ants, form long, busy trails.
Nesting sites
Ants build their nests in hidden places, such as inside walls, under floors, in soil, or in tree stumps. Some ants, like slave-making ants, invade other ant colonies and take over. Argentine ants form massive supercolonies that stretch for miles, making them very difficult to remove.
If you see small piles of dirt, sand, or wood shavings near cracks or baseboards, ants may be nesting nearby. Some species, like fire ants, prefer to nest in soil forming large, dome-shaped mounds in yards, parks, and fields.
Discarded wings
When ants start a new colony, winged male ants and queen ants fly out in swarms to mate. After mating, the males die, and the queens shed their wings before settling down to lay eggs.
If you find small, clear wings near windows, doorways, or light fixtures, it’s a sign that ants have recently swarmed and may be starting a new nest inside or near your home.
Food contamination
Ants are constantly looking for food. They prefer sweet and greasy foods but will eat almost anything, including crumbs and even pet food.
Some ants take care of aphids like farmers care for animals, protecting them in exchange for the sweet honeydew they produce. However, ants don’t just rely on aphids for food—they will also search for anything they can eat. If you notice ants inside food containers, on your countertops, or near your trash, it means they have found a reliable food source in your home.
Damaged wood
Carpenter ants—a species of black ant—don’t eat wood, but they chew through it to create tunnels for their nests. Over time, this can weaken wooden structures, causing serious damage to homes.
Signs of carpenter ants can include sawdust-like debris, rustling sounds inside walls, and wood that sounds hollow when tapped. Unlike termites, carpenter ants don’t leave mud tubes, but their damage can still be costly to repair.
As well as being able to identify the signs of an ant infestation, knowing how to keep ants away is important. If you spot any of the above signs, it’s best to contact our professional ant exterminators for an effective solution. It may be tempting to try and resolve ant problems on your own, but DIY methods often only provide temporary relief and don’t address the root of the problem.
