Pharaoh ants are one of the most difficult household ants to control in the United States. Small enough to slip through almost any crack, capable of nesting inside walls and behind appliances, and prone to explosive population growth, these insects frustrate homeowners across Des Moines, Omaha, and Kansas City every year. If you’ve seen tiny yellowish ants trailing across your kitchen counter or bathroom floor, there’s a good chance pharaoh ants are the culprit.

What Do Pharaoh Ants Look Like?

Pharaoh ants are extremely small — about 1/16 of an inch long, roughly the size of a printed period. Workers are pale yellow to light orange, with darker abdomens that can appear brownish or black. Queens are slightly larger and darker. Because of their tiny size, many people initially overlook them or confuse them with thief ants or other small species. The color — that distinctive pale, almost translucent yellow — is your best identification clue.

Habits and Behavior

Unlike many ants that nest outdoors and forage in, pharaoh ants prefer to live entirely indoors. They favor heated buildings year-round, which makes them especially problematic in apartment complexes, hospitals, grocery stores, and multi-family homes throughout the Midwest. They nest inside walls, under floors, in insulation, behind switch plates, and inside food-packaging machinery.

Pharaoh ant colonies can be enormous — ranging from a few thousand to several hundred thousand workers spread across multiple satellite colonies. They eat just about everything: sweets, proteins, fats, and even other insects. You’ll often see them trailing along pipes, baseboards, and countertops in search of food and water.

The Budding Problem

Here’s what makes pharaoh ants uniquely difficult to control: when a colony feels threatened, it doesn’t die — it buds. A queen and a group of workers simply pack up and move to a new location, starting a fresh colony. This means using sprays or repellent products on pharaoh ants often makes the problem dramatically worse. You can turn one infestation into five within weeks.

This is why store-bought sprays almost never solve pharaoh ant problems. Professional bait-based programs are the accepted standard of care for this species.

Signs of a Pharaoh Ant Infestation

  • Tiny yellowish ants in kitchens, bathrooms, or near plumbing
  • Ant trails along baseboards, pipes, or countertops
  • Ants found in food packaging or near appliances
  • Multiple small satellite colonies detected in different rooms

Health and Property Risks

Pharaoh ants don’t bite aggressively or sting, but they can contaminate food and food-prep surfaces. In medical settings, they’re considered a serious pathogen risk because they forage in sterile areas. In homes, they’re primarily a nuisance and food contamination concern. Infestations in multi-unit buildings often spread from unit to unit through shared walls and utility lines.

Prevention Tips

  • Store all food — including pet food — in sealed containers
  • Clean up grease, crumbs, and spills immediately
  • Fix leaky faucets and reduce moisture under sinks
  • Seal cracks around pipes, outlets, and baseboards
  • Avoid using spray insecticides if you suspect pharaoh ants — it makes infestations worse

When to Call a Professional

As soon as you suspect pharaoh ants, call a professional. This is not a pest where waiting or trying DIY sprays is a good strategy. A trained technician will use slow-acting bait products that workers carry back to the queen, eliminating the colony from the inside out — without triggering budding.
