Which roach species is often introduced indoors via potted plants?

• A. Surinam roach
• B. German roach
• C. American roach
• D. Oriental roach

Answer: (A)

Potted plants can carry pests because the potting soil and plant debris provide a cozy hiding and breeding place for certain roaches. The Surinam cockroach is a tropical, soil-dwelling species that thrives in organic matter found in potting mixes and greenhouse environments. When you bring a potted plant indoors, eggs or young roaches in the soil can be transported with it, and the warm, humid indoor conditions let them persist and potentially establish. In contrast, the German cockroach is more strongly associated with indoor kitchens and infested items, the American roach is typically an outdoor-invading species, and the Oriental roach favors damp indoor areas like basements, so they’re not as closely linked to plant-based transport.
