How to identify them

Pharaoh ants are among the smallest house ants — about a sixteenth of an inch — and pale yellow to light brown, sometimes with a darker rear. Their tiny size and light color make them easy to overlook until trails appear near sinks, outlets, and food.

Behavior and biology in South Florida

Pharaoh ants nest almost exclusively indoors in warm, hidden, humid spots — wall voids, behind baseboards, inside appliances and electronics, and around plumbing. A single colony has many queens.

The critical fact for control is budding: when the colony is stressed by a repellent spray, queens and workers break off and establish multiple new colonies elsewhere in the building. This is why over-the-counter sprays make pharaoh ant problems dramatically worse. They can only be controlled with the right baits that workers carry back to feed the queens and brood.

They forage for both sweets and greasy, protein-rich foods and are drawn to moisture.

Signs of an infestation

• Very small, pale ant trails near sinks, dishwashers, and outlets
• Ants appearing in bathrooms, kitchens, and around plumbing
• Problems that spread to new rooms after using a store-bought spray
• Activity concentrated in warm, humid interior areas

Why they are a problem

Pharaoh ants are more than a nuisance: they can pick up and transport bacteria, which is why they are a notorious problem in healthcare settings. In homes they contaminate food and are exceptionally persistent because of their multi-queen, budding biology.

How Bugsy’s treats pharaoh ants

We do not spray pharaoh ants. Control is built on strategic baiting: our technicians place the right sweet and protein baits along trails so workers carry the active ingredient back to feed the queens and brood, collapsing the colony from within. We map activity across the structure, avoid repellents that trigger budding, and monitor over several visits to confirm elimination.

Preventing pharaoh ants

• Never treat them with store-bought repellent sprays — it makes them spread
• Fix leaks and reduce indoor humidity
• Keep food sealed and clean up crumbs and spills promptly
• Seal cracks and gaps around plumbing, outlets, and baseboards
• Call a professional early — the sooner baited, the smaller the job
