Ants also have one or two segments connecting the thorax and abdomen. These segments, called nodes or pedicels, can help identify what type of ants you have around or in your house. You can also tell ants apart from their size. Tiny ants are about 1/16”, medium ants range from 1/16″ to 3/8″, and large ants are classified as longer than 3/8″.
