Pharaoh Ant
Monomorium pharaonis
- Order & Family
- Hymenoptera, Formicidae
- Size
- 1.5 to 2.0 mm (approximately 1/16 inch)
Natural Habitat
Typically found indoors in climate-controlled buildings, often nesting in wall voids, behind baseboards, or within electrical outlets and inaccessible crevices.
Diet & Feeding
Opportunistic omnivores that consume proteins (meat, dead insects), fats, and sweets/carbohydrates.
Behavior Patterns
They exhibit 'budding' where a queen and group of workers migrate to form new colonies. They are known for creating extensive foraging trails and are highly persistent once established.
Risks & Benefits
They are major pests in residential and medical facilities because they can mechanically transmit pathogenic bacteria (like Salmonella and Staphylococcus) to food or sterile equipment. They do not sting but can be difficult to eradicate due to their multi-queen colony structure.
