Pharaoh Ant

Natural Habitat

Widely found indoors in nesting areas such as wall voids, under floors, and behind baseboards; thrives in warm, humid environments.

Diet & Feeding

Omnivorous; they consume sugars, syrups, fats, and proteins like grease or meat, often scavenging food scraps or dead insects.

Behavior Patterns

Notable for forming 'budding' colonies where subsets move to new locations; they create extensive trail systems and are active year-round in temperature-controlled buildings.

Risks & Benefits

Significant risk as a structural pest and vector for pathogens in healthcare settings; benefits are minimal as they are highly invasive and disrupt local ecosystems.
