Pharaoh Ant (Debris/Remains)

Natural Habitat

Exclusively indoors in temperate climates, favoring unparalleled heat and humidity. Found in wall voids, under floors, behind baseboards, and often in kitchens or bathrooms.

Diet & Feeding

Omnivorous; prefers sweets (syrups, jellies) but actively seeks proteins and fats (grease, meat, dead insects).

Behavior Patterns

They exhibit 'budding' behavior where colonies split to form satellites, making them difficult to exterminate. They forage in long trails and are highly adaptable to changing food sources.

Risks & Benefits

Risks: Major household pest; capable of transmitting pathogens like Salmonella and Streptococcus; difficult to eradicate due to colony fragmentation. Benefits: General ecological cleaner in native tropical habitats.
