With nearly invisible bodies and quick, spider-like movements, ghost ants can be hard to spot. Known scientifically as Tapinoma melanocephalum, they are attracted to sinks, break rooms, and storage areas, or anywhere moisture and food sources are available.
Identification
Commonly called “black-headed ants,” ghost ants crawl across countertops, baseboards, and floors, searching for sweets, grease, or food. They follow scent trails left by worker ants, making them appear in lines or clusters.
Though small, they’re not a solitary pest. A visible trail often indicates a much larger ghost ant colony nearby, which could have hundreds or thousands of ants hidden in hard-to-reach spots.
Habitat
Outside, ghost ants nest in soil, under rocks, in leaf litter, or inside rotting wood. You can find them near foundations, under porches, or in pool enclosure frames. Indoors, they prefer humid, hidden areas like wall voids, baseboards, potted plants, or between cabinets. They can even nest in shower rods and bread boxes. Ghost ants enter buildings through tiny cracks around windows, doors, and other openings.
Ghost Ants in Florida
Florida’s warm climate suits ghost ants, making them a year-round problem. This ant species prefers to nest indoors for stable conditions and easy access to food and moisture. Their colonies can be moderate to large, ranging from 100 to over 1,000 ants, and usually have multiple queens. In homes, ghost ants can be seen foraging on kitchen counters, floors, and bathroom sinks.
Ghost Ants Behaviors, Threats, or Dangers
The ghost ant does not sting and only bites when threatened. Indoors, activity is typically concentrated in the kitchen, although any room can be infested. Ghost ant behavior can be frustrating as they trail from room to room under the edge of carpeting.
In kitchens and pantries, they prefer to forage on sweets but will also feed on grease. They tend homopterans (a sucking insect) for honeydew and feed on both live and dead insects. Since ghost ants need moisture, they often trail to shower stalls, bathtubs, sinks, and toilets. If you suspect a ghost ant infestation, it is best to consult a professional ant exterminator.
Are Ghost Ants Hard to Get Rid of?
Yes, they are. Their colonies often spread across multiple locations, making DIY methods only partly effective. Killing foraging ants doesn’t remove the queens or core nest, so the problem can return without thorough treatment. Professional ghost ant control involves finding entry points and nesting sites and using slow-acting baits that the ants carry back to the colony.
How Many Ghost Ants Count as an Infestation?
Even a few visible ants can mean hundreds more are nearby. Ghost ant infestations can be subtle and worsen over time. Frequent sightings near food or moisture could suggest a larger hidden population elsewhere.

Frequently Asked Questions
Why Do I Have Ghost Ants In My Home?
Ghost ants are drawn to moisture and food. Kitchens and bathrooms provide both. Even small crumbs or leaky pipes can attract them.

They get inside through tiny gaps in foundations, windows, doors, and utility access points. They might also travel in from nearby plants touching your home.
What Do Ghost Ants Eat?
Their diet includes sugars, greases, honeydew from insects, and other insects. Indoors, they’re attracted to sweets, crumbs, and anything with protein or fat.
How Can I Prevent A Ghost Ant Infestation?
Keeping a clean home, especially in food prep and wet areas, is key. Sealing cracks, removing standing water, and storing food in airtight containers can help lower the risk.
Are Ghost Ants Dangerous?
While they don’t pose serious health risks, ghost ants can contaminate food and surfaces. Their persistent nature and large colonies make them a significant nuisance, especially in homes, restaurants, and healthcare facilities.
