Palmetto Bug vs Cockroach: What’s the Difference & How to Get Rid of Them
A palmetto bug is the common name Floridians give to the large American cockroach, Periplaneta americana. It’s a cockroach—just rebranded to sound less alarming.
People say “palmetto bug” because the word “cockroach” triggers disgust and property-value panic. Realtors, hotels, and locals swap the terms to soften the image, even though it’s the same brown, winged pest hiding under palm fronds and kitchen sinks.
Key Differences
There are none. “Palmetto bug” is regional slang; entomologists classify it as a cockroach. Southerners hear “cockroach” and picture infestations; they hear “palmetto bug” and picture a lone outdoor wanderer.
How to Get Rid of Them
Seal cracks with silicone, remove food crumbs nightly, and place gel baits like Advion along baseboards. For heavy infestations, hire a licensed pest-control operator who uses IGRs and perimeter sprays.
Why do they fly at me?
They’re startled by light or movement; warm air currents lift them, so they glide—often straight at the nearest heat source (you).
Do palmetto bugs carry more germs than other cockroaches?
No. Germ load depends on environment, not nickname. Any roach that crawls through sewers can spread bacteria.
