Carpenter Ants vs. Black Ants: Know the Difference
By Shumaila Saeed & Hifza Nasir || Published on May 12, 2025
Carpenter ants are larger and build nests in wood, potentially damaging structures, while black ants (often referring to common black garden ants) are smaller, nest in soil, and are less destructive to buildings.
Key Differences
Carpenter ants, identifiable by their size, ranging from 6 to 12 mm, prefer to nest in moist wood, leading to structural damage over time. Black ants, typically smaller at about 3 to 5 mm, often nest outdoors in soil or under rocks, posing less threat to buildings.
