American Cockroach

Periplaneta americana

Active:Active year-round in heated buildings; increased indoor activity in cooler months

American cockroaches are the largest common cockroach species, measuring 1.5 to 2 inches in length with a reddish-brown body and yellowish figure-eight pattern behind their heads. Often called palmetto bugs or sewer roaches, they have wings and are capable of short flights. Despite their name, they're native to Africa and the Middle East. These cockroaches are common in commercial buildings, sewers, and steam tunnels.

Habitat & Behavior

American cockroaches prefer warm, moist environments and live in sewers, storm drains, steam tunnels, basements, crawl spaces, and around plumbing. They enter buildings through sewer connections, drains, and gaps around utility lines. Indoors, they inhabit laundry rooms, bathrooms, kitchens, and areas with high humidity. Unlike German cockroaches, they're more common in commercial settings than residences. They aggregate in large groups and produce a characteristic musty odor.

Signs of Infestation

  • Large reddish-brown cockroaches crawling in basements, bathrooms, or kitchens
  • Cockroaches emerging from drains, especially at night
  • Dark brown, cylindrical droppings with ridges along the sides
  • Egg capsules (oothecae) that are dark brown and about 3/8 inch long
  • Strong, musty odor indicating large populations
  • Smear marks on walls near floor level where cockroaches travel

Health & Property Risks

American cockroaches spread bacteria including Salmonella, E. coli, and Staphylococcus through contact with sewage and decomposing matter. They contaminate food preparation areas, stored food, and surfaces with their droppings and body secretions. Their shed skins and feces trigger allergies and asthma attacks. While they bite rarely, their presence indicates sanitation or plumbing issues. These cockroaches can live up to two years, and females produce 800+ offspring during their lifetime.

Prevention Tips

  • Repair leaky pipes, faucets, and eliminate standing water sources
  • Install drain covers and keep floor drains filled with water to prevent entry
  • Seal cracks and gaps around plumbing penetrations and utility lines
  • Reduce humidity using dehumidifiers in basements and crawl spaces
  • Store food in sealed containers and maintain clean kitchen conditions
  • Fix drainage problems and eliminate moisture issues in crawl spaces
