    What is a Little Black Ant?

    Little Black Ants (Monomorium minimum) are tiny omnivores who scavenge for their food. Because of this, you may occasionally see them invade your home. They’re similar in appearance to a Pharaoh Ant, but they’re stark black. They nest in the dirt, but occasionally in wood or masonry, as well. These are the ants your mother threatened you with to get you to clean up your food messes.  “Do you want to get ants?”

    What Do Little Black Ants Look Like?

    Little Black Ants are, not surprisingly, very small and jet-black. They do have a stinger, and they will, in fact, bite, but their small size means you may never even notice either.

    Signs of an Infestation

    When dealing with an infestation of Little Black Ants, you may not notice immediately. – They are named aptly and creatures this small tend to go overlooked – until there appear in larger numbers. So what can you look for if you suspect an infestation?

    Frequent Sightings: Spotting a high number of little black ants indoors, especially in kitchens, pantries, or areas where food is stored, is the most easily identifiable indication of an infestation.

    Ant Trails: Observing well-defined trails or lines of ants moving in a coordinated manner, often along baseboards, countertops, or walls, is a sign of an established ant colony.

    Presence of Nests: If they’re already inside your home, they’ll typically nest in hidden areas, like cracks in walls or behind baseboards. Finding small piles of dirt or tiny openings that serve as entry points to their nests suggests an infestation.

    Food Sources: The presence of little black ants near food sources, including crumbs, spills, or sugary substances, indicates that they are actively foraging and infesting the area.

    Tunnels in Wood: Sometimes, little black ants may infest wooden structures, such as window frames or door frames, creating small tunnels or galleries within the wood.

    Foul Odor: When little black ant colonies are disturbed or crushed, they release a characteristic odor that can be described as musty or rotten, which may become noticeable in heavily infested areas.

    Outdoors Nesting: Little black ants may build nests outdoors, usually in soil, under stones, or in decaying wood. Finding ant mounds or activity near the foundation of a building suggests potential indoor infestation.

    Little Black Ant Prevention

    You can prevent an infestation of little black ants, though, not to worry. The most important and probably most obvious prevention method is to keep your home clean. All food – even your pet’s food – should be secured and sealed at all times. Clean up spills and don’t let sticky things stay sticky. Regularly remove your trash from your home and place it in a secure bin.

    Make sure your home has effective seals on all doorways and windows to prevent them from entering your home. Inspect your home for cracks, gaps, or openings, and ensure you seal them to prevent entry. Regularly trim bushes and vegetation so they don’t act as bridges to your home. 

    How to Get Rid of Little Black Ants

    Don’t worry if you suspect a little black ant invasion in your home. Contact PMi and we’ll schedule a home inspection to check things out. We’ll chat about possible signs that little black ants might be hanging around. We’ll do some detective work in your yard by inspecting the soil, the exterior of your home, and even loose bark to spot any ant nests. Once we’ve found a problem, we’ll kick into action with the perfect plan to show those ants who’s boss. So relax; we’ve got you covered!



    Little black ants prefer soil nests, so if you come across small craters of fine soil on the ground, those could be markings for their nest openings. Don’t be surprised if you find them nesting in woodwork or masonry of buildings, as well.
