Monomorium pharaonis
- Order & Family
- Hymenoptera: Formicidae
- Size
- 1.5 to 2.0 millimeters (very small)
Natural Habitat
Widely distributed throughout the world. Prefers warm, humid indoor environments like kitchens, bathrooms, and hospitals.
Diet & Feeding
Omnivorous and opportunistic. Consumes sweets, fats, proteins, and other insects. In hospitals, they are known to feed on blood or wound secretions.
Behavior Patterns
Form large, multi-queen colonies. They do not swarm; instead, they expand through 'budding,' where a group leaves to start a new nest. They are highly persistent and can travel through electrical wiring and plumbing.
Risks & Benefits
They are a major nuisance pest and a significant health risk in medical facilities as they can mechanically transmit pathogens like Salmonella and Streptococcus. They provide minimal ecological benefit in human-occupied structures.
