Large yellow ants

The Large yellow ant


Large Yellow Ants (Acanthomyops interjectus) are characterized by their distinctive yellowish coloration and large size, typically ranging from 1/8 to 1/4 inch in length. They have segmented bodies with a noticeable waist, and their antennae feature twelve segments with no distinct club at the end.


These ants often prefer moist environments and nest beneath rocks, logs, or soil in outdoor settings. They may also establish nests indoors in damp or decaying wood, particularly in areas prone to water leaks or humidity.


Large Yellow Ants are primarily scavengers, feeding on honeydew produced by aphids, as well as dead insects and other organic matter. They are not aggressive towards humans but can become a nuisance when nesting indoors, especially in structures with moisture issues.

Signs of Infestation:

  1. Sightings: Large Yellow Ants are often seen foraging in trails, especially during warmer months.
  2. Nest Locations: Look for nests outdoors in soil or under objects like rocks and logs. Indoors, they may nest in moist wood or wall voids.
  3. Damage: While they do not cause structural damage, their presence indoors can indicate moisture problems.


  1. Eliminate Moisture: Address any moisture issues, such as leaks or high humidity, to discourage nesting.
  2. Seal Entry Points: Seal cracks and crevices where ants may enter buildings.
  3. Cleanliness: Keep surfaces clean and free of food debris to reduce attractiveness to foraging ants.
  4. Professional Pest Control: For persistent infestations, consider contacting a pest control service, like “Get Em Out Wildlife Control“, for effective management and prevention strategies.


Regular inspection and maintenance of structures for moisture problems and sealing potential entry points can help prevent infestations of Large Yellow Ants. Effective Ant Pest Control measures are crucial for long-term prevention.
