Smokybrown Cockroaches
Smokybrown cockroaches are large, uniformly dark mahogany-brown cockroaches that are strong fliers and highly attracted to light. They are closely related to American cockroaches but are slightly smaller and lack the yellow head markings. They are a major outdoor and peridomestic pest throughout the Southeast and Gulf Coast, commonly found in tree holes, mulch, gutters, and attic spaces. Their strong flight ability means they frequently enter homes through open doors, windows, and roofline gaps. They require high humidity and are most problematic in subtropical environments.

Key Behaviors
Smokybrown cockroaches are nocturnal and strongly attracted to exterior lighting, which draws them to porches, patios, and entry points. They commonly nest in tree holes, palm thatch, gutters, soffits, and attic spaces. They require consistent high humidity and will dehydrate quickly in dry environments. They feed on plant material, decaying organic matter, and household food scraps.
Risks & Concerns
Smokybrown cockroaches contaminate food and surfaces with bacteria and allergens. Their strong flight ability allows them to colonize attic spaces and upper floors that other cockroach species rarely reach. Large populations in trees and gutters adjacent to homes create persistent reinfestation pressure that is difficult to manage without addressing exterior harborage.
