How to recognize a real Pharaoh ant
- Very small, light yellow to amber body with a darker abdomen
- Two-node waist and a three-segment antennal club

1. Red Imported Fire Ant
A small, aggressive reddish-brown ant that builds dome-shaped mounds of loose soil in sunny lawns and fields across the southern US. When disturbed, workers swarm and sting repeatedly.

2. Odorous House Ant
A small, dark brown to black ant that trails along counters and sinks looking for sweets. Crushed workers give off a smell often compared to rotten coconut.
How it differs:
- Color: Pharaoh Ants are yellow and tan; odorous house ants are black and brown.
- Signature feature: Pharaoh Ants: very small, light yellow to amber body with a darker abdomen. Odorous House Ants: small, uniformly dark ant with an uneven thorax.
3. Little Black Ant
A tiny, jet-black, shiny ant that nests in lawns, under rocks and in wall voids. Workers form narrow trails to sweets, grease and meats.
How it differs:
- Color: Pharaoh Ants are yellow and tan; little black ants are black.
- Where found: look for Pharaoh ants in the kitchen and in the bathroom; little black ants turn up in the kitchen and in lawns and grass.
- Signature feature: Pharaoh Ants: very small, light yellow to amber body with a darker abdomen. Little Black Ants: very small, glossy jet-black body.

When you'll see Pharaoh ants
Pharaoh Ants are most active in spring, summer, fall and winter. In spring, overwintering adults become active and many species lay their first eggs. Summer heat speeds up development, so populations can grow quickly. In fall, many bugs look for shelter, and some move toward or into buildings. In winter, activity continues mainly indoors in heated spaces.
Typical places to check: kitchen and bathroom.
About ants
The Pharaoh ant is one of the ants. Ants live in colonies ruled by one or more egg-laying queens. The workers you see are sterile females foraging for the rest of the colony, so killing visible ants rarely solves anything. Winged ants, called swarmers, appear when a mature colony sends out new kings and queens.
Bait works because workers carry it back and share it with the queen and larvae. Repellent sprays can scatter the colony and make the problem harder to fix.
Are Pharaoh ants or their lookalikes dangerous?
- Pharaoh Ant: They don't bite, but in hospitals and kitchens they can carry bacteria onto clean surfaces.
- Red Imported Fire Ant: Fire ant stings burn, form white pustules, and can cause severe allergic reactions in sensitive people.
- Odorous House Ant: Odorous house ants are a nuisance only; they rarely bite and don't sting.
- Little Black Ant: Little black ants have a sting too weak to feel; they are a nuisance only.
