Not every ant crawling across your kitchen counter is a carpenter ant or an odorous house ant, even though those two get most of the attention. New Jersey has a much longer roster of ant species, and every so often one of them shows up looking so different from the usual suspects that it throws people off completely. Two good examples are the acrobat ant and the citronella ant. Most homeowners already recognize the trailing lines that mean it's time for odorous house ant control, or the small dirt mounds along a driveway that signal pavement ant control season. These two are different, though, and each has a trait that makes identification pretty simple once you know what to look for.
Meet The Acrobat Ant
Acrobat ants earn their name honestly. When something bumps their nest or gets a little too close, they raise their heart-shaped abdomen straight up and forward, arching it over their thorax and head almost like a scorpion getting ready to strike. It's a real defensive posture, and once you've seen it, you won't mistake an acrobat ant for much else. In terms of color, they run dark brown to black, and viewed from above, that abdomen has a distinct heart shape instead of the oval or teardrop outline you'd see on other species.
Acrobat ants favor moist or decaying wood, which is exactly why they sometimes turn up in the same beams, sills, or door frames where carpenter ants have already been active. That doesn't mean the acrobat ants caused the damage. More often, it just means the wood was already soft or wet enough to attract more than one wood-loving species at once. Either way, finding acrobat ants indoors is worth treating as a cue to check the wood and moisture nearby, not just an ant problem on its own.
Meet The Citronella Ant
Citronella ants are a different story altogether. They're yellowish-brown and noticeably bigger-bodied than most of the household ants people are used to seeing, which alone makes them stand out. The real giveaway, however, is the smell. Crush one, or step on one by accident, and you'll get a sudden, strong burst of lemony, citronella-like scent — exactly where the name comes from.
What really grabs homeowners' attention is how citronella ants swarm. Each spring, large numbers of winged citronella ants can emerge from the ground all at once, and because the swarm is so sudden and so large, it's frequently mistaken for a termite swarm. In fact, that mix-up alone probably triggers more nervous phone calls than the ants themselves deserve.
Side-By-Side: Shape, Smell, And Swarm Behavior
Put the two next to each other and the differences are easy to spot in seconds. Here's how acrobat ants and citronella ants compare on the traits that matter most:
| Feature | Acrobat Ant | Citronella Ant |
|---|---|---|
| Body Shape | Heart-shaped abdomen, raised up over the thorax and head when disturbed | Standard ant build, but noticeably larger-bodied than common household ants |
| Color | Dark brown to black | Yellowish-brown |
| Distinct Trait | "Acrobatic" defensive posture when threatened | Strong lemony, citronella-like smell when crushed |
| Typical Nesting Spot | Moist or decaying wood, sometimes near existing carpenter ant damage | Outdoors and underground, rarely inside the home |
| Structural Risk | Can point to compromised or wet wood nearby | Minimal — mostly a normal seasonal swarm event |
Why A Citronella Ant Swarm Isn't A Termite Emergency
If you've just watched a small cloud of winged insects pour out of a crack in the patio, it's natural to assume the worst. In reality, a citronella ant swarm is one of the least concerning things that can happen in an NJ yard each spring. Unlike termites, citronella ants live mostly outdoors and underground, so they aren't feeding on structural wood inside your home the way a termite colony would. Their swarm is simply a seasonal event — the colony sending out reproductive ants to start new colonies nearby, almost always outside.
That said, the confusion makes sense. A sudden swarm of hundreds of winged insects looks alarming no matter what's behind it, and telling a termite swarmer from a citronella ant swarmer at a glance isn't easy if you don't do it every day. When in doubt, the smell test settles it fast: a crushed citronella ant smells distinctly like lemongrass, while termites don't. Still, getting a second opinion beats guessing, especially when the wrong guess means either overreacting or ignoring something real.
Whether you're dealing with an acrobat ant working through damp, compromised wood or just a springtime citronella ant swarm passing through the yard, the fix starts with getting the ID right. That's exactly what professional ant control is built around — matching the treatment to the actual species instead of guessing and hoping. Ants are rarely the only question on a homeowner's mind this time of year, either. A family that hears scratching under the porch might reach out about rodent control in Montclair before it becomes a bigger problem, while a Belleville homeowner watching a papery nest grow under the eaves usually ends up calling about wasp control in Belleville, not ants at all. If two lookalike ants can cause this much confusion, plenty of other pests can too. When you're not sure what you're looking at, we're happy to take a look before you guess wrong.
