Prevention Methods

  • Eliminate standing water
  • Keep tree branches and plants cut back from house
  • Seal all cracks and openings


Argentine ants deposit trails of food continuously, instead of just from nest to food source. This habit ensures they do not waste time revisiting the same area for food. Argentine ants prefer to eat sweets, but they will eat almost anything including meats, eggs, oils and fats.


Argentine ant colonies are located in wet environments near a food source. Outdoors, they usually build shallow nests under boards or stones, beneath plants or alongside sidewalks. Argentine ants may seek shelter indoors when it becomes too wet or too dry outside.


Argentine ants do not pose a health threat, but they can contaminate food.
