What Do Ghost Ant Nests Look Like?

Ghost ant nests are not easily visible like the mounds of other ant species. They prefer to nest inside structures, behind walls, under floors, in insulation, or in other hidden, enclosed spaces. Indoors, ghost ants may nest inside walls, under cabinets or sinks, in hollow doors, or in various cracks and crevices. Outdoors, they will nest under stones, mulch, logs, or leaf litter. Their nests are made up of small cavities and tunnels. Spotting the ants traveling to and from the nest is usually the best way to locate it.

Signs of a Ghost Ant Nest

Seeing a trail of ghost ants – Following the ants may lead you back to the nest location.

piles of dead ants – Ghost ants remove dead ants from the nest and pile them outside the entrance.
Wings – Watch for the presence of winged ants, which indicates a mature nest.
Sawdust-like material – Ghost ants eject a sawdust-like nesting material from the nest entrance.

How to Find Hidden Ghost Ant Nests

Finding concealed ghost ant nests takes some detective work. Here are some tips for tracking them down:

Follow the Ant Trail

The best way to locate a hidden ghost ant nest is to follow the ants’ trails. Watch where the ants are coming from and going to. Backtrack along their path, looking for cracks or entry points. Focus your search near moisture sources like kitchens, bathrooms, and laundry rooms.

Use Bait to Find the Nest

Place small bait stations or drops of sugary liquid, such as honey or simple syrup, in areas where you have seen ant activity. The ants will carry the bait back to the nest to share it with the rest of the colony. After an hour or more, check the bait placement spots – if ants are gathered there, use them to locate the nest.

Conduct Searches at Night

Since ghost ants are most active at night, conduct nest searches after dark when ants will be out in full force. Turn off lights so you can track them with a flashlight. The darkness will also encourage them to venture out.

Listen for Nest Sounds

Press your ear against walls, floors, and other potential nest sites to listen for subtle rustling noises which may indicate a nest cavity.

Look for Hidden Entry Points

Inspect along baseboards, under sinks, around pipes and electrical outlets, and inside cabinets for tiny cracks and crevices where ants may be entering. These could lead back to a hidden nest.

How to Find Ghost Ant Nests Outdoors

Ghost ants also nest frequently in outdoor locations. Here are some signs that may indicate an outdoor ghost ant colony and tips for tracking it down:

Inspect Trees, Stumps, and Logs

Carefully examine trees, stumps, logs, and firewood piles near the home. Ghost ants often nest in small hollows and cracks in wood.

Check Under Objects on the Ground

Overturn pots, rocks, debris, and mulch to check for signs of ant activity. A nest may be underneath.

Look in Leaf Litter and Soil

Ghost ants build shallow nests under leaf litter or in soil. Carefully rake back leaves and mulch or dig into soil to uncover nest entrances.

Follow Ants Up Trees

If you see ants trailing up and down tree trunks, they may be nesting in hollows within the tree. Examine the tree closely for entry holes.

Effective Methods to Eliminate Nest

Once you have located the ghost ant nest, you can use these effective methods to eliminate it:

Use Ant Killer Sprays

Apply a residual spray insecticide labeled for ant nests directly into nest entry points, tunnels, and trails. This will kill ants inside the nest.

Utilize Ant Bait

Place ant gel baits or bait stations near nest entrances. Worker ants will carry the bait back to the nest and feed it to the queen, eventually killing the colony.

Pour Boiling Water

Pour boiling water directly into accessible nest sites. This will kill ants on contact and destroy the nest.

Use Dusts in Wall Voids and Crawl Spaces

Inject dust insecticides into wall voids, crawl spaces, attics, and other enclosed nest areas. The dust will adhere to ants entering and exiting the nest.

Remove Outdoor Nests

Physically remove outdoor nests you can access, such as under rocks, logs, or in stumps. Seal up cracks and crevices they are using as entry points.

Vacuum Indoor Nests

Use a vacuum hose to suction up visible ant trails and entry points inside. This can remove a portion of the colony.

Call a Pest Control Professional

For large infestations or hard to find nests, call in a professional pest control company. They have the proper tools and expertise to locate and eliminate ant nests.

Prevention Tips

After eliminating a ghost ant infestation, take these steps to help prevent future ones:

Caulk and seal cracks and crevices on the exterior of your home.

Keep yard debris and woodpiles away from the foundation.
Trim back trees and bushes touching the structure.
Store food in sealed containers and don’t leave dirty dishes out.

Fix leaky pipes and other moisture issues.
Apply a perimeter insecticide treatment around your home.

Finding and destroying ghost ant nests is challenging but important for getting control of them. Focus your search efforts near moisture and follow ant trails back to their source. Combining nest elimination with preventive measures will help keep these sneaky ants out of your home for good.

Frequently Asked Questions

Where are ghost ant nests usually located?

Indoors, ghost ants usually nest behind walls, under kitchen or bathroom cabinets, within insulation, or in cracks in baseboards and foundations. Outdoors, they nest under rocks, mulch, woodpiles, trees, and in the soil.

What attracts ghost ants?

Ghost ants are attracted to sugary foods and liquids. They also need moisture and will be drawn to sources of water such as kitchens, bathrooms, pipes, and condensation.

How do you kill a ghost ant nest?

Effective ways to eliminate a ghost ant nest include spraying ant killer directly into nest entrances, using ant gel baits near the nest, pouring boiling water on the nest, applying dust insecticides to wall voids, and vacuuming. Removing outdoor nests also helps.

Do ghost ants bite or sting?

Ghost ants do not bite or sting. While they can be a nuisance, they do not pose a health risk to humans or pets. They get their name from their ability to seemingly disappear.

Conclusion

Ghost ants can be annoying and difficult to control. Finding their hidden nests is key to getting rid of an infestation. Look for signs like ant trails and focus your search near moisture sources and in cracks and crevices.

Ghost ants, whose scientific name is Tapinoma melanocephalum, are pale yellowish-white ants native to tropical regions around the world. They are also called odorous house ants due to the coconut-like smell they emit when crushed. While the ants themselves are only about 1/16 inch long, their colonies can number in the tens of thousands. This allows them to quickly infest structures in search of food and moisture.

Some key facts about ghost ants include:

They have a high reproduction rate, with each queen capable of laying up to 300 eggs per day.
Nests can be located indoors or outdoors and may move locations frequently.
Foraging workers follow invisible pheromone trails, making the ants appear to vanish and reappear randomly.

Colonies contain multiple queens, making them harder to exterminate.
Ghost ants feed on sweets, proteins, fats, and dead insects.

Ghost ants pose several challenges for homeowners trying to eradicate them:

Their small size enables them to exploit narrow cracks and crevices to enter and nest in structures.
They are active hunters that will infest a variety of foods inside pantries and kitchens.
If the scent trails are not eliminated, ants will continue to return to previous nesting areas.

Nests may be widely dispersed, requiring extensive treatment to fully eradicate colonies.

However, there are several steps homeowners can take to both remove current ghost ant infestations and prevent future ones:

Seal cracks in foundations and openings around pipes to block entry points.

Clean food debris and water sources to remove attraction factors.
Use pesticide sprays and baits labelled for ant elimination.
Locate and directly treat nests for most effective control.

Reduce exterior moisture and yard debris near the home’s foundation.

Ghost ants can multiply rapidly, making infestations difficult to control. Stopping them requires diligence in locating nests, removing food sources, and sealing off entry points. Combining these strategies can provide effective and sustainable control of ghost ant populations.
