Thief Ants - Mangodreads [CC BY-SA 4.0 (https://creativecommons.org/licenses/by-sa/4.0)] Very small 1/16" long and yellow to light brown or orange color

Thief Ant - This ant gets its name from the fact that it steals food, as well as the young from other ants. The thief ant is the smallest of our commonly encountered household ants - only 1/16". Its small size enables it to get into food containers where other ants cannot; also other ants are unable to follow the thief ant into its tunnels. The thief ant will not eat sugar, but prefers fats.

Control of the Thief Ant:
  • Thief ants are more likely to have an outside nest than Pharaoh ants so an outside barrier strip should be a part of a control program for the homeowner.
  • Pesticides are useful in controlling this ant.
  • Although this ant may nest inside all year long, it is thought by some to nest inside more frequently in hot weather. Following the trails to the nest is reportedly difficult, but should be attempted.
  • Control should be centered around the pantry and other food sources, as well as around sinks and other moisture sources. Natural voids such as the area under kitchen cabinets or nearby wall voids should be dusted with a residual dust.
