Pharaoh Ant
Monomorium pharaonis
- Order & Family
- Hymenoptera: Formicidae
- Size
- 1.5 to 2.0 mm (approx. 1/16 inch)
Natural Habitat
Exclusively indoor dwellers in cooler climates, preferring heated, humid areas like kitchens, bathrooms, wall voids, and near hot water pipes. They nest in extremely small, unusual crevices.
Diet & Feeding
Omnivorous; prefers sweets, syrups, and honey but readily feeds on proteins like meats, grease, dead insects, and even shoe polish.
Behavior Patterns
They exhibit 'budding' behavior where a single queen breaks away from the main colony with workers to start a new nest, leading to rapid infestations that are widely dispersed. They are persistent foragers that create well-defined trails.
Risks & Benefits
Significant household pest; notorious for spreading pathogens (Salmonella, Streptococcus) in sterile environments like hospitals. They are very difficult to eradicate due to their budding capability, often worsening if sprayed with standard insecticides.
