How To Identify an Odorous House Ant

Odorous house ants are dark brown to black in color. They are 1/8 of an inch long with the workers being of one size. They have one node (bump between middle and rear body sections), but it is difficult to see.

Odorous house ants get their name because the emit an odor similar to coconuts when disbursed or smashed. They also raise their abdomens in air and run around when disturbed. 

Where Do They Come From

Odorous house ants can build nests indoors and outdoors. If the nest is outside it will be a shallow nest in mulch next to building and in soil under protection. If the nest is inside it can be found in wall voids and under carpet, usually near water pipes or heaters.

Tips & Tricks

How To Keep Ants Away

  • Trim back any shrubs or trees that come into contact with buildings. When plants touch a home or building they create an easy way for ants to crawl onto and access the building.
  • Seal all potential ant entryways. Common entry ways are around windows, doors, and utility lines.
  • Keep dry pet food in sealed bins and clean up any spills.
