Pharaoh Ants: Identification, Habitat, Behavior, and Control

Pharaoh ants are a common household ant species that pose significant challenges in pest control. Their global distribution and adaptability make them one of the most difficult ants to control. This guide provides valuable information about Pharaoh ants, including identification features, their Latin name, and effective extermination techniques.

Pharaoh Ants


  • Size: Pharaoh ants are tiny, measuring approximately 1.5 to 2 mm long.
  • Color: They vary in color from yellowish or light brown to red, with the abdomen often darker or blackish.
  • Body structure: Pharaoh ants have 12-segmented antennae with a 3-segmented club. The head, thorax, petiole, and postpetiole have dense punctuations and a dull or subopaque appearance. The body is sparsely covered in hairs, and the eyes are comparatively small.

Latin Name

The scientific name for Pharaoh ants is Monomorium pharaonis (Linnaeus) (Insecta: Hymenoptera: Formicidae).

Extermination Techniques

Pharaoh ants can be challenging to eliminate due to their nesting habits and large colonies. Here are some common extermination techniques used for Pharaoh ant control:

  1. Baiting: Baiting is one of the most successful methods for Pharaoh ant control. Non-repellent baits containing slow-acting insecticides are preferred because they allow worker ants to carry the bait back to the colony, effectively targeting the entire population. Baits should be placed near foraging trails, nest entrances, and areas where ants are frequently seen. It is important to use fresh and effective baits and regularly monitor and replenish them for continued control.
  2. Chemical control: Insecticide sprays can be used to target Pharaoh ant colonies directly. These sprays are applied to trails, nest sites, and potential harborage areas. It is important to choose insecticides labeled for ant control and follow the instructions carefully. However, caution must be exercised when using sprays to avoid causing the colony to scatter and create additional satellite colonies.
  3. Dusts and residual sprays: Dusts and residual sprays containing insecticides can be used in areas where Pharaoh ants are nesting or trailing. These formulations provide long-lasting control by creating barriers that ants must pass through. Dusts are typically applied in voids, cracks, and crevices, while residual sprays are used along ant trails and entry points. It is important to choose products specifically labeled for indoor ant control and use them according to the manufacturer’s instructions.
  4. Integrated Pest Management (IPM): Implementing an IPM approach can enhance the effectiveness of Pharaoh ant control. IPM combines multiple strategies to target ants at different stages of their life cycle. This may include sanitation practices to eliminate food and water sources, sealing entry points to prevent ant access, and regular monitoring to identify active areas for treatment. By integrating various techniques, the reliance on pesticides can be minimized while achieving long-term control.
