The odorous ant is a small brown ant measuring about 1/8 inch in length. Odorous ants get their name from a sour coconut odor that they give off when crushed. They can be confused with the Argentine ant, except they have one flattened node, not pointed. Their node is not usually visible from above or from the side because it is hidden by the abdomen.

The odorous house ant is closely related to the ghost ant but is easily distinguished by size and coloration. Odorous house ants rival Argentine and crazy ants in their persistence in invading buildings. It’s basic biology and habits are similar to those of the Argentine ant.

The control techniques for odorous similar to that of other invading ant types. They can have multiple queen colonies and number in the tens of thousands of workers in any given colony.

Rather than going after the colonies directly, perimeter control is most important in control of odorous ant infestations. These ants can have multiple colonies nearby measuring in the tens of thousands of workers each with a complex network of “roads” in -between them. Maintaining a perimeter barrier is often enough to cut off the ants that are inside and get the outside colonies to choose a different target.

Odorous Ant Locations 

  • Under the loose bark of trees
  • In cavities in trees
  • In bird and animal nests, including honey bee hives.
    • The colonies locate themselves in the top of the hives, apparently for the warmth the hive produces.
    • In wall voids – particularly around hot water heaters and hot water pipes.

    Dusting these areas with Borid Dust will provide good control. Outside perimeter treatments with residual sprays such as Termidor, Demon WP or Talstar are especially helpful. Odorous house ants love sweet baits containing sugar and or honey such as the Drax Combo Syringe or Gourmet Liquid Ant Bait.
