Ants
Ants are among the most common and persistent pests found in and around homes. These social insects live in colonies that can range from a few dozen individuals to hundreds of thousands, depending on the species. While most ants are harmless, some - like the Argentine ant and odorous house ant - are notorious for invading kitchens and pantries in search of food. Carpenter ants, on the other hand, can cause significant structural damage by hollowing out wood to build their nests.
Why Ants Invade Homes
Ant colonies are highly organized and consist of different castes, including queens, workers, and occasionally males. Workers search for food, care for the young members of the colony, and protect the nest. Ants communicate using pheromones, which are chemical signals that allow them to mark trails, alert others to danger, or coordinate complex tasks. This efficient communication is what enables them to quickly overwhelm an area once a food source is found.
Ant Colonies & Nesting Sites
Most ant infestations start outdoors, especially near foundations, gardens, or landscaping features. Cracks in walls, windows, or doorways provide easy access indoors. Once inside, ants tend to travel in visible trails, especially in areas where crumbs, sweets, or moisture are present. Kitchens, pantries, and bathrooms are frequent targets. Odorous house ants, for instance, emit a foul, rotten-coconut smell when crushed.
Ant Behavior & Food Preferences
Different species have different food preferences. Some are attracted to sugars, while others love proteins or fats. This variety means that multiple types of bait or treatment may be needed to fully address an infestation. Odorous house ants, for instance, are particularly drawn to sweet foods and emit a rotten coconut smell when crushed.
Preventing & Eliminating Ants
To prevent ants, block entry points, remove water and food sources, and target colonies at their source. Store food in sealed containers, wipe down surfaces regularly, and fix any leaks that create damp areas. While store-bought sprays may kill individual ants, they rarely eliminate the colony. For persistent or large infestations, professional pest control may be necessary to locate and treat the nest directly. Identifying the species is often key to determining the most effective treatment method. With their teamwork, adaptability, and large numbers, ants can be surprisingly difficult to control without a targeted approach.
