Know Your Enemy
Sugar ants are really odorous house ants. They are small and black, commonly found indoors. Pavement ants prefer driveway cracks and rarely show up inside. Larger ants, like carpenter ants, pose structural threats and have very different treatment needs. Then there are velvety tree ants, which are also larger and less common inside.

Sugar Ant Description
Size
The sugar ant is very small—measuring about 2.4-3.3mm long. They are typically about as small as a pencil eraser. Although they are small, they quickly become noticeable as they swarm around food or stream through your home in a line.
Color
Sugar ants are typically black in color.
Smell
This might sound strange, but when crushed, sugar ants release an unpleasant, coconut-smelling odor. Sugar ants have a gland that releases this smell and it’s why they are called the odorous house ant.
