Flying ants are sexually mature reproductive members of an existing colony, often referred to as alates or swarmers.
In Pennsylvania and New Jersey, these winged insects are almost always carpenter ants, embarking on nuptial flights to mate and establish new colonies. Unlike other species, carpenter ants burrow into softwood to nest; if left untreated, a flying ant infestation can cause significant structural damage to the wood framing and furniture around your property.
Flying ants emerge during the humid summer months to mate, a process that often brings them into contact with residential properties that contain standing water or decaying wood. Rural properties in the forests of the Poconos, Burlington County, NJ, or the Lehigh Valley are at a higher risk of these pests.
Openings around windows and bright outdoor lighting often act as beacons, drawing swarms toward your home as they seek a hospitable environment to start a new nest.
Correctly identifying flying ants vs. termites is the most critical step for any homeowner, as termites cause damage much more rapidly and are much more difficult to eradicate without professional help. Understanding these distinctions is vital to determining the severity of the threat and whether you need a targeted treatment.
This guide helps you identify flying ants throughout the region, implement strategies to prevent them from entering your home, and know exactly when to call a professional exterminator.
What Are Flying Ants?
In Eastern Pennsylvania and New Jersey, flying ants, also called alates, swarmers, or reproductives, are sexually mature carpenter ants seeking to reproduce. Queen ants spawn them, and worker ants feed them until the colony is ready to expand.
These ants swarm when a colony reaches a certain size, and environmental conditions are right. This usually happens on warm, humid days following a rainstorm. You will often see them in large groups around doorframes, windows, or light fixtures.
Spotting flying ants ensures that a local carpenter ant infestation is nearby.
How to Tell Flying Ants Apart from Termites
Flying ants and termites look similar at first glance, but key physical differences help you distinguish between them. Identifying them correctly matters because termites cause significant structural damage to homes, while flying ants typically do not.
Use this table to tell these flying insects apart:
| Feature | Flying Ants | Termites |
| Waist | Pinched, narrow “wasp-like” waist. | Broad, straight, and uniform waist. |
| Wings | Two pairs; front wings are longer than the back. | Two pairs of equal length and shape. |
| Antennae | Bent or “elbowed.” | Straight and look like tiny beads. |
| Body Color | Usually dark brown, black, or reddish. | Often translucent, tan, or “milky” white. |
If you’re unsure which pest you’re dealing with, contact a pest control professional. Misidentifying termites as flying ants can lead to costly structural damage over time.
Do Carpenter Ants Fly?
Yes, some carpenter ants can fly. These winged carpenter ants are swarmers that emerge to mate and establish new colonies.
After male swarmers fertilize females, the males die, and the females shed their wings, land, and start new colonies. While most flying ants will not damage wood, once they establish a colony, carpenter ants will damage wood in your home as they burrow into it to create nesting sites.
When Are Flying Ants Most Active in Pennsylvania and New Jersey?
Flying ants swarm during warm months because temperature and humidity trigger their mating flights. In the tristate area, you’ll typically see swarms in late spring through early fall, with peak activity in July and August.
Swarms usually occur after rain, when the ground is moist and conditions are ideal for establishing new colonies. Swarming often occurs simultaneously across entire neighborhoods because environmental triggers affect all nearby colonies at once.
If you see a swarm near your home, it means there’s likely an established ant colony nearby. The swarm itself is temporary, but the colony that produced it will remain unless treated.
How Do Flying Ants Enter Your Home?
Flying ants enter homes by exploiting small cracks, gaps, and openings like any other ant. Common entry points that attract flying ants include:
- Cracks in foundations, walls, and window frames
- Gaps in your roof line or openings in your attic
- Gaps around doors and windows
- Openings around utility lines and pipes
- Vents and chimneys
- Torn window screens
Once inside, flying ants are attracted to light sources. You’ll often find them gathered near windows, lamps, and other bright areas.
They’re also drawn to moisture and food sources. Kitchens, bathrooms, and basements with high humidity are particularly attractive to them.
Signs of a Flying Ant Infestation in Your Home
While seeing a few flying ants doesn’t always mean you have an infestation, certain signs indicate a more serious problem:
- Large numbers of flying ants inside your home, especially near windows
- Discarded wings near windowsills, doors, or other entry points
- Visible ant trails leading to and from your home
- Piles of sawdust or frass (wood shavings) if carpenter ants are present
- Hollow-sounding wood when tapped
- Small holes in wood surfaces
If you notice multiple signs or a large number of flying ants, an established colony is likely nearby.
Carpenter ants, once established, are nocturnal and can often be seen foraging for food, moisture, and wood to burrow in.
Addressing the problem immediately will mitigate any structural damage and prevent them from entering your home.
How to Prevent Flying Ants from Invading Your Property
Preventing flying ants requires eliminating attractants and sealing entry points around your property. These steps are essential for homeowners in Eastern Pennsylvania and New Jersey due to high seasonal humidity.
Exterior Maintenance
- Trim Vegetation: Regularly cut grass and trim hedges away from the foundation.
- Clear Debris: Remove dead tree branches and fallen leaves from your yard.
- Store Firewood Properly: Keep woodpiles at least 20 feet from your home and elevated off the ground.
- Manage Water: Clear clogged gutters and empty birdbaths to eliminate standing water.
- Fix Wood Damage: Repair or replace rotting wood on decks, siding, and fences.
Interior Maintenance
- Store Food: Use sealed containers for all pantry items.
- Manage Waste: Remove trash from the home daily.
- Seal Gaps: Use caulk to close cracks and crevices in the foundation and walls.
- Control Moisture: Fix leaky pipes and faucets immediately.
- Check Screens: Repair or replace torn window and door screens.
Natural Deterrents
- Peppermint Oil: Spray a mixture of peppermint essential oil and water near entry points.
- Diatomaceous Earth: Sprinkle food-grade powder around windowsills and doors.
- Vinegar Solution: Clean surfaces with vinegar and water to erase ant scent trails.
These prevention methods work best when combined. Addressing moisture issues, sealing entry points, and removing attractants together create the most effective barrier against flying ants.
When to Call a Pest Control Professional About Flying Ants
Many homeowners in Pennsylvania and New Jersey dismiss flying ants as a minor nuisance, but waiting can lead to expensive structural repairs. While ants don’t eat wood like termites, they hollow it out to build “galleries,” which can be just as damaging to your home’s stability.
Contact a local exterminator if:
- You see swarmers indoors: Large numbers of flying ants inside usually mean a mature colony is already nested in your walls.
- You find “Frass”: Piles of fine sawdust mixed with insect parts (frass) near baseboards indicate active excavation.
- You hear rustling: In quiet moments, you may hear a faint clicking or rustling sound inside your walls as ants move through their tunnels.
- You find discarded wings: Piles of wings near entry points or windowsills are a primary sign of an active infestation.
- You see structural changes: Doors or windows that suddenly stick or floors that feel “spongy” can indicate that internal beams have been weakened by tunneling.
Ant infestations in the Mid-Atlantic often involve “satellite” colonies. While you might kill the ants you see, the parent colony is often hidden outdoors in a tree stump or woodpile. A professional inspection identifies these hidden sources to prevent the ants from returning every season.
If you suspect an infestation in Eastern Pennsylvania or South Jersey, contact The Pest Rangers immediately. We identify the specific ant species and eliminate the colony at the source to protect your property.
FAQs
What time of year are flying ants most common in NEPA?
Flying ants are most common during warm summer months, particularly in July and August in the northeast. However, they can also appear during spring and fall depending on weather conditions. Warm, humid days following rain are prime conditions for flying ant swarms.
Do flying ants pose any health risks?
Flying ants are typically harmless to humans and do not pose health risks. Some flying ants may bite or sting if threatened, but these bites are usually not painful. Still, you should keep them away from food and out of your home to prevent contamination and potential infestations.
How long do flying ant swarms last?
Flying ant swarms typically last only a few hours to a day. The mating flight is brief, and once mating occurs, males die and females land to establish new colonies. However, if conditions remain favorable, you may see multiple swarms over several days or weeks.
Are flying ants a sign of an infestation?
Seeing flying ants outside doesn’t necessarily mean you have an infestation, but finding them inside your home often indicates an established colony nearby. If you see multiple flying ants indoors or find discarded wings, a colony is likely present in or near your home.
Can flying ants damage my home?
Most flying ants do not damage homes. However, flying carpenter ants can cause structural damage because they burrow into wood to create nesting sites. If you see flying carpenter ants, contact a pest control professional immediately to prevent damage.
What attracts flying ants to my home?
Flying ants are attracted to light sources, moisture, and food. Common attractants include outdoor lights at night, leaky pipes, clogged gutters, exposed food, and decaying wood. Eliminating these attractants helps prevent flying ants from entering your property.
How do I know if I have carpenter ants or regular flying ants?
Carpenter ants are typically larger than other ant species and are black or dark brown. Look for piles of sawdust (frass) near wood structures, hollow-sounding wood, and small holes in wood surfaces. If you’re unsure, a pest control professional can identify the species.
Will flying ants go away on their own?
Flying ants may disappear after their brief mating flight, but the colony that produced them will remain. If conditions are favorable, the colony will continue to grow and produce more swarmers. Professional treatment is the most reliable way to eliminate the colony.
