American cockroach
Periplaneta americana
- Identification
- Large (1.5–2 inches), reddish-brown with a pale figure-8 behind the head. Sometimes called a 'water bug.'
- Lifecycle & behavior
- Prefers warm, damp areas — basements, drains, boiler rooms. Long-lived compared with German roaches.
- When it's active in Central NY
- Found in commercial buildings, basements, and steam tunnels; can move up from sewers and drains. Year-round indoors.
- Risk & damage
- Contaminate surfaces and can spread bacteria through the damp, dirty areas they travel.
- Why DIY falls short
- Surface sprays don't reach the moist harborage and drain sources sustaining them.
- How we treat it
- Targeted treatment of harborage and moisture areas, drain and void attention, and moisture-reduction guidance.
American cockroach or German cockroach?
Size settles it immediately. American cockroaches are large — up to about an inch and a half — reddish-brown, with a pale yellowish figure-eight pattern behind the head. German cockroaches are roughly half an inch with two dark lengthwise stripes. If it is big and reddish, it is not a German cockroach.
American cockroaches in Central New York
In this climate American cockroaches are associated with warm, damp infrastructure rather than kitchens: boiler rooms, steam tunnels, sewer and drain systems, floor drains, and the basements of large older commercial buildings. They are much less common in ordinary homes here than in warmer regions.
When they do appear in a home, the source is usually a drain, sewer connection, or a shared basement in an older multi-unit building rather than an indoor breeding population. Finding and closing the route matters more than treating the individuals you see.

American cockroach — common questions
I saw one huge roach in my basement. Do I have an infestation?
Not necessarily. American cockroaches usually enter from drains, sewer lines, or a warm damp shared basement rather than breeding in the living space. One or two sightings often means a route rather than a population. Finding where it came in is the useful step.
