You see a large, dark insect skitter across your kitchen floor. Your neighbor calls it a “palmetto bug.” Your friend shakes their head and says it’s just another cockroach. So, who’s right – your neighbor or your friend – and how do you tell the difference between palmetto bugs and cockroaches?

Well… they’re both right. “Palmetto bug” is a nickname for a few different kinds of cockroaches, so essentially “palmetto bugs” and “cockroaches” are the same pest. The confusion comes from different regional nicknames and the fact that these pests thrive all over our sunny state.
Let’s dive deeper into the subtle distinction between palmetto bugs and cockroaches – and what to do if you’re dealing with them in your home.
What Types of Cockroaches Are Palmetto Bugs?
Not all roaches go by “palmetto bug,” but almost anytime you hear that term, you’re dealing with a cockroach. While these species have slight differences in color, size, and preferred hiding spots, they’re all cockroaches that Floridians often lump together under the “palmetto bug” umbrella:

- American Cockroach: One of the largest common roaches, often reddish-brown in color, and notorious for popping up in warm, humid environments.
- Smoky Brown Cockroach: A deep mahogany-brown pest that’s highly attracted to moisture and can sometimes be found near gutters, under palm fronds, or hiding in damp corners.
- Florida Woods Cockroach: Native to our region, this roach is sometimes slower and clunkier than its cousins, but it still gives off that unsettling vibe.
- Australian Cockroach: Large but not quite as large as American roaches, the two species are easily mistaken for each other. Unlike American cockroaches, which are all reddish-brown, Australian cockroaches have a yellow coloring that runs down the sides of their thoraxes.
Are Water Bugs Palmetto Bugs?
Here’s where things can get confusing. Water bugs often look a lot like cockroaches, and depending on where you live, you might hear people call them palmetto bugs too. If someone says they saw a “palmetto bug,” you might walk over and find it’s actually a water bug.
But remember, “palmetto bug” isn’t an official term—there’s no scientific definition behind it. In many cases, people just use it to label any big, creepy bug that scuttles around at night. So, when in doubt, don’t stress too much over the exact name. Whether it’s a cockroach or a water bug, odds are you want it out of your home right away.
Are Florida Woods Cockroaches Palmetto Bugs?
Yes. In fact, Florida Woods Cockroaches may be the original “palmetto bugs.” Early settlers in our region likely coined the name after spotting these pests around palmetto trees.
And since different species of roaches can look so similar, the term gradually spread to include American Cockroaches, Smoky Brown Cockroaches, and more. Over time, “palmetto bug” became a catch-all for various roaches scurrying around Florida backyards, patios, and kitchens.

Why Are They Called Palmetto Bugs?
It’s all about location, location, location! In the Southeast — particularly here in Florida — palmetto trees are common, and people often find these roaches hanging out under the fronds. Naturally, the bugs took on the name of their favorite hideout. In other parts of the country without palmetto trees, no one bothers calling them “palmetto bugs.”

Fun fact: South Carolina is nicknamed “The Palmetto State,” so you’ll often hear the term there, too. Since Florida Woods Cockroaches aren’t as common in many areas of South Carolina, residents typically mean the American or Smoky Brown Cockroach when they say “palmetto bug.”
Are Palmetto Bugs Harmful?
The biggest hazard with palmetto bugs is they’re unsanitary. They spend their time in filth and can easily spread germs and bacteria throughout your house. Other than that, palmetto bugs are not particularly harmful to humans, although they do sometimes bite.
What Happens When a Palmetto Bug Bites You?
Getting bit by a palmetto bug can hurt in the moment, but don’t worry – it’s not a big deal. Palmetto bugs are not venomous and they don’t transmit any diseases when they bite. Wash it with soap and water, put a bandage on it, and you should be fine.
