It sounds like a bad indie horror movie title. Or maybe some weird, niche agricultural disease. But if you’ve spent any time walking through the West Village or catching the filtered chaos of Manhattan TikTok lately, you know that pumpkin spit on New York is a very real, very sticky phenomenon that happens every single autumn. It’s not actually human saliva—thank god—but rather the gooey, fermented, and often projectile-like residue left behind by the city's annual obsession with over-the-top stoop displays.
New York City loves a theme. We go hard.
When October hits, the brownstones in neighborhoods like Chelsea, the Upper West Side, and Brooklyn Heights turn into literal orange jungles. We’re talking hundreds of pumpkins per building. But here’s the thing about New York: it’s humid, it’s crowded, and the squirrels are basically on steroids. Within a week, those pristine gourds start to cave in. They liquefy. And because of the way our architecture works—tall stairs, narrow sidewalks—that rotting pumpkin "spit" ends up everywhere.
The Science of the Sludge
Why does this happen so aggressively here? It’s a mix of biology and urban heat islands. Pumpkins are roughly 90% water. Once you carve a Jack-o'-lantern, you’re essentially creating a Petri dish. In the cramped quarters of a New York City street, heat gets trapped between the buildings. This accelerates the breakdown of the polysaccharides in the pumpkin's cell walls.
Basically, the pumpkin starts digesting itself.
The "spit" is the byproduct of this anaerobic decomposition. It’s a viscous, foul-smelling liquid that leaks out of the carved mouths and eyes of the decorations, trailing down the stone steps. Honestly, if you’ve ever slipped on a patch of it while rushing for the C train, you know it’s slicker than ice. It’s a hazard.

Local sanitation experts and "stoop-scapers"—the professional decorators wealthy New Yorkers hire to deck out their homes—have to deal with this constantly. Sarah Meyer, a floral designer who works on high-end residential displays in Manhattan, notes that the lifespan of a carved pumpkin in the city is often less than four days before the "spit" starts to ruin the aesthetic. Most people don't realize that a pumpkin sitting on a concrete step is basically a ticking time bomb of organic decay.
Why Pumpkin Spit on New York is a Logistics Nightmare
New York doesn't have "yards" in the traditional sense. Everything happens on the sidewalk. When pumpkin spit on New York sidewalks becomes a literal puddle, it attracts the city’s unofficial mascot: Rattus norvegicus. The common brown rat.
To a rat, a fermenting, leaking pumpkin is a five-star buffet.
- The sugar content in the "spit" provides high energy for the winter.
- The moisture helps them stay hydrated without venturing to leaky pipes.
- The soft, decaying flesh is easy to transport back to burrows.
It’s a cycle. The pumpkin spits, the rats come, the sidewalk becomes a biohazard, and suddenly your "cute" fall photo op is a crime scene. This has led to some pretty intense debates in neighborhood Facebook groups. Some residents are calling for a "carving ban" on public-facing stoops, suggesting that people stick to uncarved gourds which take months, rather than days, to break down.
But New Yorkers are stubborn. We want our spooky season.

The Viral Infamy of the "Spit"
The term started gaining traction on social media as a way to describe the specific, frothy bubbles that appear on the surface of decaying pumpkins during a warm October "Indian Summer." If you search for pumpkin spit on New York online, you'll find countless videos of disgruntled commuters filming the carnage.
It’s become a bit of a local meme. "Watch out for the pumpkin spit" is the new "watch out for the puddle that looks shallow but is actually three feet deep."
There’s also the smell. You can’t talk about this without mentioning the scent. It’s a cloyingly sweet, vinegary aroma that hangs in the air of the West Village around October 25th. It’s the smell of a thousand pumpkins surrendering to the elements. Some people find it nostalgic. Most people find it revolting. It’s the reality of high-density living meeting seasonal enthusiasm.
How to Avoid the Mess (and the Rats)
If you’re one of the people contributing to the pumpkin spit on New York landscape, there are ways to be less of a nuisance. You don't have to let your stoop turn into a swamp.
- The Bleach Method: A light spray of 10% bleach solution can kill the bacteria and fungi that cause the liquefaction. It’s not great for the environment, but it stops the spit.
- WD-40: Some people swear by spraying the inside of the pumpkin with WD-40 to keep it from "drooling." It keeps the moisture in the cells longer.
- Elevation: Put your pumpkin on a small wooden block or a plate. Don’t let the "spit" touch the stone directly; it can actually stain certain types of historic brownstone.
- The "No-Carve" Rule: Use paint or stickers. Seriously. It looks just as good and prevents the 3:00 AM rat party on your doorstep.
The Cultural Significance of the Rot
Maybe there’s something poetic about it. In a city that’s constantly being scrubbed, gentrified, and polished, the pumpkin spit on New York is a reminder of the organic mess of life. It’s temporary. It’s gross. It’s very "Old New York."

Even the high-end boutiques on Madison Avenue aren't immune. You’ll see a $5,000 coat in the window, and right outside on the pavement, a $5 pumpkin is slowly melting into a puddle of orange goo. It’s the great equalizer.
Ultimately, the phenomenon is a testament to the city's spirit. We do things to the extreme. We don't just put out a pumpkin; we put out fifty. And we don't just let them sit there; we watch them dissolve into the pavement as a sacrifice to the changing seasons. Just... maybe wear boots if you're walking through Brooklyn this week.
What to do if you encounter the "Spit"
If you're a property owner, the best thing you can do is stay ahead of the decay. Once the pumpkin starts to feel soft or "hollow" at the base, it's already too late. The spit is coming. Toss it in the compost bin (NYC has expanded curbside organics collection for a reason!) before it becomes a sidewalk hazard.
For pedestrians, the rule is simple: if the pumpkin looks like it’s screaming, it’s probably leaking. Give it a wide berth. If you do happen to get some on your shoes, warm water and dish soap are your best friends. Don't let it dry; the sugars in the pumpkin "spit" act like a glue once they dehydrate, making it surprisingly difficult to remove from suede or canvas.
The season is short. The pumpkins are iconic. The mess is inevitable. Welcome to autumn in the city.
Practical Next Steps for New Yorkers:
- Check your local DSNY schedule: Make sure you know which days are "brown bin" days so your decaying pumpkins don't sit on the curb for a week.
- Buy late: If you're carving, wait until October 29th or 30th. The "spit" usually takes 48-72 hours to start in New York's micro-climate.
- Use Vinegar: A soak in a vinegar-water bath after carving is a natural way to delay the onset of the "spit" without using harsh chemicals like bleach.
- Report Hazards: If a neighbor's display has become a literal slip-and-fall hazard on a public sidewalk, you can actually call 311. It's technically a sidewalk obstruction once it starts leaking onto public property.
