Known for their tiny size, large colonies, and ability to survive indoors year-round, pharaoh ants are considered one of the hardest ant species to control once an infestation takes hold. Their tendency to build nests inside heated buildings makes them a significant problem for both homeowners and businesses.
At Gregory Pest Solutions, we provide residential and commercial pest control services designed to effectively target pharaoh ants. Because colonies can split and multiply if improperly disturbed, DIY sprays and repellents often worsen infestations. Professional pharaoh ant control is the most reliable way to reduce colonies and address the conditions that attract these ants in the first place.

Size: About 1/16 inch (1.5–2 mm)
Antennae: Yes, 12 segments with a three-segmented club at the tips
Region: Found throughout the United States, especially in warm, humid buildings such as hospitals, hotels, and homes; nests in wall voids, behind baseboards, and inside appliances or insulation.
Pharaoh ants (Monomorium pharaonis) are as small as the little black ant, measuring no more than 2 mm in length.
Workers are yellow to light brown with darker abdomens, which can make them hard to see on certain surfaces. Because of their pale coloring, many people confuse them with thief ants or other small species. Some people even refer to them as black pharaoh ants, although their true coloration is closer to tan with darker markings.
Colonies are highly mobile, and workers can easily relocate if disturbed. Because of this, infestations may appear to vanish temporarily, only to reappear somewhere else in the same structure.
Although workers are wingless, colonies produce reproductive ants that can fly. The public rarely sees these flying pharaoh ants, but they are essential to the colony’s survival. Their ability to establish new nests quickly is one of the main reasons infestations spread so easily.
Pharaoh ants are social insects that thrive in large colonies. Unlike some ant species with a single queen, colonies often contain multiple queens that produce eggs simultaneously. This means that even if a colony is disturbed, it can split into several smaller colonies, each with its own queen. This process, called budding, is one of the reasons pharaoh ants are so challenging to control.
Their broad diet includes:
Unlike many ants that build large outdoor mounds, pharaoh ants nest in wall voids, behind baseboards, in cracks, electrical outlets, and even in linens or clothing. In commercial buildings such as restaurants, hospitals, or apartment complexes, pharaoh ants can quickly spread across multiple units, making it much harder to trace the source.
The pharaoh ant's life cycle begins with eggs laid by queens. These eggs hatch into larvae, which workers feed until they pupate and become adult ants. Workers live for several weeks, while queens may live for months, continually producing offspring. Because multiple queens are active at once, populations can reach tens of thousands within a single building.
One of the most common signs of a pharaoh ant infestation is the long, thin trails of ants traveling between food sources and hidden nests.
Healthcare facilities are also vulnerable. Ants can access equipment, medication storage, or patient areas, creating sanitation and hygiene risks. Repeated ant activity around food, water sources, or warm appliances strongly indicates a colony is nearby.
By paying attention to these signs, residents and business owners can detect pharaoh ant infestations early and seek professional treatment before colonies grow out of control.
Pharaoh ants could be considered somewhat dangerous to public health. They carry bacteria picked up while foraging, which can then be spread to food preparation areas, medical equipment, or clean rooms.
However, they do not sting and bites are not as harmful as fire ant bites.
Pharaoh ants are especially troubling in healthcare settings where sanitation is critical, like emergency departments pharmaceutical labs, and other sterile units. Their ability to move freely through heated buildings makes them one of the most invasive ant species indoors.

Standard pest control techniques for ant prevention focus on eliminating access to food, water, and shelter, while maintaining a high level of cleanliness. Dispose of garbage regularly in covered bins and store all pantry items (like cereal) in sealed containers. Additionally, regularly inspect the outer perimeter of your property for any cracks or holes and seal them immediately. By removing these potential attractants and entry points, you make your environment far less inviting for pharaoh ants.
However, because colonies can split and reproduce rapidly, even the best prevention efforts may not be enough once an infestation has begun. DIY sprays and repellents often scatter colonies, causing them to spread further. Professional pharaoh ant extermination is recommended for long-term results.

Their colonies contain multiple queens, and when disturbed, they split into new colonies in a process called budding. This makes DIY control methods ineffective and often worsens infestations.
They eat sweets, grease, proteins, and dead insects. Indoors, they are especially drawn to sugary foods and pantry items.
While foraging, they can pick up bacteria from unsanitary areas and transfer it to food or surfaces. This is especially concerning in hospitals, restaurants, and kitchens.
Sprays often kill only visible ants and cause colonies to scatter. This leads to budding, which increases the number of nests rather than reducing them.
Colonies reproduce through multiple queens laying eggs and by budding, where parts of the colony break off to form new nests. This allows infestations to expand quickly within buildings.
