If you've lived in Tallahassee for more than a summer, you've met one: the big reddish-brown roach — up to an inch and a half — that turns up on the porch, in the garage, or flying at the outside light on a warm night. That's a palmetto bug, which is really the American cockroach, and finding one says almost nothing about how clean your house is.
Palmetto bug or German roach?
This distinction matters, because the two are treated completely differently. Palmetto bugs are large, live primarily outdoors, and wander in — from mulch beds, sewers, tree holes, woodpiles and the humid spaces under the house. German roaches are small, light brown, and breed indoors in kitchens and bathrooms, which is a much more involved problem. See our side-by-side guide and our cockroach control page.
Why they come inside in Tallahassee
Our climate is the reason. Tallahassee's heat, humidity, tree canopy and heavy summer rain create ideal outdoor roach habitat, and palmetto bugs move indoors seeking moisture and shelter — especially during heavy rain or a dry spell, and as it cools in fall. Common entry points are gaps under doors, plumbing penetrations, weep holes, soffit and roofline gaps, and drains.
Where do they hide?
Indoors they head for moisture — under sinks, in bathrooms, in the laundry, around water heaters, and in crawl spaces and attics. Outdoors they cluster in mulch, leaf litter, palm trees (hence the name), woodpiles and sewer lines.
How we keep palmetto bugs out
Because they live outside, the fix is an exterior-first perimeter approach plus exclusion: treating the harborage and entry zones around the foundation, sealing the gaps they use, and managing the moisture and mulch that draw them. We target the specific points they enter rather than fogging your living space.
The honest truth: because palmetto bugs live outdoors, you can't eliminate them from the environment — Tallahassee is their habitat. The realistic goal is keeping them out of your home, which sealing and a maintained perimeter do reliably.
Seasonal timing
Palmetto bug pressure peaks in the warm, wet months and pushes indoors during weather swings. A quarterly perimeter plan keeps the barrier fresh year-round, which matters here because we barely get an off-season.
