"That yellow figure-eight mark behind the head β that's how you know it's an American cockroach, not just any roach."
πͺ³ Big, Fast, and Flying In: American Cockroaches Are on the Move in Pinellas County
If you've seen a large reddish-brown roach glide across your patio or dart out from under a sink, you've likely met the American cockroach β Florida's largest and most common cockroach, and the true origin of the local nickname "palmetto bug."
How to identify them:
π Reddish-brown body, typically 1.5 to 2 inches long β one of the largest roaches in Florida
π A distinctive yellowish figure-eight marking on the shield behind the head (pronotum)
π Fully developed wings on both males and females β they can't sustain true flight, but they glide short distances when dropping from trees, rooflines, or ceiling beams
π Fast-moving and most active at night
Why they're surging right now:
Summer humidity and daily rain in Pinellas County push American cockroaches out of their normal outdoor habitat β storm drains, sewers, mulch beds, and woodpiles β and toward higher, drier ground. That often means your garage, porch, bathroom, or the gaps around foundation cracks, plumbing lines, and vents. They're drawn to moisture, so leaky pipes and damp crawl spaces are magnets.
Why it matters beyond the "ick" factor:
American cockroaches breed and feed in unsanitary areas β sewers, garbage, septic systems β and can contaminate food and surfaces as they move through your home. Heavy infestations often carry a distinct musty odor, along with small, ridged, dark droppings and reddish-brown egg casings tucked into dark corners.
