Grease Ants: Identification, Habitat, Behavior, and Control

Welcome to our comprehensive guide on grease ants (Solenopsis molesta), a bothersome ant species known for their persistence and food-seeking behavior. As pest control experts in the field, we are delighted to share valuable information about these pesky pests, including identification tips, their scientific classification, and effective methods to eliminate them from your environment.

Grease Ants


Grease ants are small ants measuring about 1/16 to 1/8 inch in length. They have a yellowish-brown to dark-brown coloration and appear shiny. One distinguishing feature is the presence of a distinct “node” or bump between their thorax and abdomen. Grease ants are often attracted to greasy or sweet substances, making kitchens, pantries, and food storage areas common areas of infestation.

Latin Name

The scientific name for grease ants is Solenopsis molesta. The genus name “Solenopsis” is derived from the Greek words “solēn,” meaning tube or pipe, and “opsis,” meaning appearance or aspect, referring to the ants’ tube-like appearance. The species name “molesta” originates from the Latin term meaning troublesome or annoying, highlighting their ability to be a nuisance in homes and businesses.

Extermination Techniques

Effective control of grease ant infestations requires a multifaceted approach that targets both the visible ants and their hidden nests. Here are some common extermination techniques employed by professionals:

  1. Baiting: Grease ants can be successfully eliminated using ant baits specifically formulated to attract and eliminate these pests. The ants carry the bait back to their colonies, distributing it among the colony members and leading to their eradication.
  2. Residual Insecticides: Applying residual insecticides in areas of grease ant activity helps disrupt their trails and prevents their access to food sources. This approach aims to create a barrier that inhibits their movement and discourages their presence.
  3. Improved Sanitation: Maintaining a clean and hygienic environment is essential to deter grease ants. Regularly clean up spills, properly store food in sealed containers, and promptly address any sources of grease or food residue.


While DIY methods may provide temporary relief, grease ants can be persistent and challenging to fully eliminate without professional assistance. A qualified ant control service can assess the situation, implement targeted treatments, and offer long-term solutions.
