🪳 Brown-Banded Cockroach

🔍 Identification

10-14mm; light brown with two distinctive yellowish-brown bands across the wings; males can fly. KEY ID: look high in rooms — they prefer temperatures above 80°F and are found near the ceiling, behind wall decorations, inside electronics and appliances (including TVs, microwaves, and clocks), and in upper cabinet areas.

🧬 Biology & Behavior

Unlike German cockroaches (which concentrate near food, moisture, and heat), brown-banded cockroaches are more evenly distributed throughout a structure and prefer dry, warm environments. They scatter egg cases in high locations — glued under furniture, behind wall decorations, inside electronics. This high, scattered distribution is why gel bait applied low in kitchens misses them.

⚠️ Damage & Health Risk

Food contamination; psychological disturbance; allergenic proteins that trigger asthma; difficult elimination due to scattered distribution throughout structure.

🔧 DIY Treatment

Place gel bait HIGH — inside cabinet hinges near the top, behind picture frames, above the refrigerator top, and in electronics access areas. Sticky traps in upper cabinet areas confirm activity. Pyrethroids applied to upper wall surfaces and behind wall outlets. Thorough treatment of ALL rooms, not just kitchen.

👷 When to Call a Pro

Whole-structure treatment is required — brown-banded cockroaches in wall voids throughout the building require professional access to treat effectively.
