Shown are some of the cockroaches that may be found in the Southwest Florida area.
German Roach
Blattella germanica – German roaches are small, fast-moving cockroaches that are closely associated with indoor environments. In Naples, they are most commonly found in kitchens and bathrooms where warmth, moisture, and food sources are consistent. Unlike outdoor roach species, German roaches reproduce indoors and are often discovered when populations have already begun to establish.
Australian Wood Roach
Periplaneta australasiae – Australian wood roaches are primarily outdoor cockroaches commonly found in landscaped areas throughout Southwest Florida. In Naples, they are most often associated with mulch beds, palm debris, and damp organic material around homes. They are attracted to moisture and light, which is why they may occasionally wander indoors, but they typically do not establish indoor infestations.
Surinam Roach
Pycnoscelus surinamensis – Surinam roaches are soil-dwelling cockroaches commonly found in gardens, potted plants, and mulch throughout Southwest Florida. In Naples, they are often encountered when landscaping is disturbed or when plants are moved, since they live and reproduce in soil rather than inside structures. When found indoors, they are typically associated with moisture and plant material rather than established nesting areas.
American Cockroach
Periplaneta americana – Commonly found outdoors in Southwest Florida, American cockroaches are attracted to moisture and are often seen entering homes during heavy rain. In Naples, they are frequently encountered around drains, garages, and landscaped areas rather than as true indoor infestations.
Frequently Asked Questions
What types of cockroaches are most commonly found in Southwest Florida homes?
In Southwest Florida, homeowners commonly encounter several different types of cockroaches, but they do not all behave the same way. Larger roaches, such as American and Australian wood roaches, are often associated with outdoor moisture, landscaping, and drainage areas and may occasionally wander indoors. German roaches, by contrast, are closely tied to indoor living spaces and are most often found in kitchens and bathrooms where food, warmth, and moisture are consistent.
