Palmetto bug is the common South Florida name for the American cockroach (Periplaneta americana). They are the large, reddish-brown cockroaches (1 to 1.5 inches long) that most South Florida homeowners encounter. Unlike German cockroaches, which infest inside and are extremely difficult to eliminate once established, palmetto bugs are primarily outdoor insects. They live in storm drains, mulch beds, under leaf litter, in sewer systems, and around landscape debris. They enter homes seeking water, food, or shelter — they don't establish large indoor colonies the way German roaches do.

Yes. Palmetto bug, American cockroach, and Florida woods roach are all names used in South Florida for large roaches. The American cockroach (Periplaneta americana) is the species most homeowners encounter. The Florida woods roach (Eurycotis floridana) is a related species — slower, stockier, and often found under bark and in mulch. The German cockroach (Blattella germanica) is a different species entirely: smaller, tan-colored, and a true indoor infesting pest that reproduces rapidly and is much harder to eliminate. When South Florida homeowners call about palmetto bugs, they almost always mean American cockroaches.

Palmetto bugs enter homes through foundation gaps, under exterior doors without adequate sweeps, around pipe penetrations (under sinks, around HVAC lines), through drains, through attic vents, and around utility conduits. South Florida's warm climate means they're active year-round with no winter interruption. Properties with heavy mulch close to the foundation, standing water, or large trees near the home provide ideal habitat. After heavy rain, palmetto bugs often move from flooded outdoor habitat (storm drains, mulch beds) into higher ground — which means your home during and after a storm.

Yes, American cockroaches have fully developed wings and can fly, though they prefer to run. They fly more readily in hot weather and are attracted to light. In South Florida's summer heat (90+ degrees), flying palmetto bugs are more common — they're often seen flying toward porch lights at night. This is a normal behavior and not an indication of infestation severity.

The most effective approach combines perimeter pest treatment with structural exclusion. Perimeter treatment creates a toxic barrier around the foundation that palmetto bugs must cross to enter — and don't survive. Exclusion means sealing entry points: installing door sweeps on all exterior doors, caulking around pipe penetrations under sinks and around HVAC lines, sealing around utility conduits, and screening attic vents. Reducing outdoor habitat (pulling mulch 6 inches from the foundation, reducing excessive moisture near the home) addresses the breeding and resting environment that sustains them.

Perimeter pest treatment every 60 to 75 days provides effective year-round suppression for most South Florida properties. This interval reflects the residual life of the treatment product and the recolonization rate of American cockroaches. Year-round service is recommended because South Florida has no winter to reduce outdoor populations. Properties with significant pressure — large trees, storm drain adjacency, heavy mulch, or older homes with foundation gaps — may benefit from more frequent initial treatments to break the cycle.
