Follow The Trail
Place a tiny bit of food down and watch where they go. You can often trace them back to the nest this way. Indoors, they love warm areas, especially between 70 and 86 degrees. In colder months, they may stay inside completely.

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.
