How to Kill & Prevent Palmetto Bugs

Palmetto Bug vs. Cockroach

A palmetto bug is a term commonly heard in the Southeast that refers to several different species of cockroaches. In South Carolina, the term palmetto bug usually refers to the smokybrown cockroach, while Floridians are usually referring to the Florida woods cockroach. The American cockroach is also called a palmetto bug.

All cockroach species referred to a palmetto bugs are about the same size, have wide, glossy bodies, and are all various shades of brown and reddish-brown. Several of the species, like the smokybrown cockroach, can be found in palmetto trees in the Southeast (hence the name).

Where Are Palmetto Bugs Found?

Palmetto bugs like moist, humid areas. In your home, you'll find them in your bathrooms, kitchen (under sinks, behind dishwashers, and under refrigerators), attics, and crawlspaces. Outdoors you'll find them around septic tanks, trash bins, and in mulched gardens, leaf litter, and trees.

Health Concerns

Just like cockroaches, palmetto bugs can pose health risks. They can spread several harmful pathogens, including salmonella which can contaminate food. As they walk across your counters and floors, they leave behind feces and sheddings that can cause allergic reactions and asthma attacks in some people. Palmetto bugs have also been known to bite people which can cause skin irritation.

Keep Palmetto Bugs Out of Your Garden

Your perfectly maintained garden bed is just as appealing to a palmetto bug seeking food as the overflowing dumpster down the street. However, excessive mulch is especially attractive to palmetto bugs, so maintain your mulch at the proper 2-3 inch depth and don't pile it against the foundation of your home. Also, don't leave your pet's food and water outside. If you have a problem with palmetto bugs in your landscape, control them with Ortho® Home Defense® Insect Killer for Lawn & Landscape.
