Sugar Ants—Surprisingly
Despite not being destructive, odorous house ants are hard to eliminate because they often have multiple interconnected colonies. Treat one, and another might still be active nearby.

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.
