If you’re noticing tiny black ants marching across your kitchen counters or along baseboards, you may be dealing with little black ants—one of the most common nuisance ants found in California homes.
They’re small, persistent, and great at finding food sources. While they aren’t dangerous, they can quickly become a recurring frustration if not properly addressed.
Common Name: Little Black Ant
Scientific Name: Monomorium minimum
Key Traits:
Little black ants are most active from May through September, when warm weather drives heavy foraging. During the peak of summer, heat and dry conditions often push them indoors in search of water, leading to increased sightings inside homes.
Activity slows significantly from December through February, when cooler temperatures keep most ants hidden in their nests—though indoor activity can still occur in heated homes.
Little black ants are easy to miss individually—but their trails give them away.
If you’re seeing a steady line of ants traveling to a food source, there’s likely a colony nearby.
This ability to spread is one reason infestations can be difficult to fully eliminate without addressing the colony's source.

Here are answers to some common questions we hear from homeowners:
Many homeowners use the term “sugar ants” to describe small ants attracted to sweets. Little black ants are often called sugar ants, but several species can fall under that nickname.
Yes. Many infestations start outdoors, but ants regularly travel indoors to forage for food and water.
Most little black ants you see do not have wings.
However, reproductive ants (called swarmers) can develop wings at certain times of year and leave the nest to start new colonies.
