The idea that a cold climate protects a city from cockroaches doesn't hold up in Pittsburgh. Buildings are heated for months, basements are warm and damp, and apartments share walls and pipes. Add food service in neighborhoods like the Strip District and South Side, and roaches have a comfortable home.
German roaches versus American roaches in Pittsburgh
The German cockroach is the one that lives inside people's kitchens and bathrooms. It is light brown, about half an inch long, and spreads between apartments along pipes and wall voids or hitchhikes in groceries and boxes. Student rentals in Oakland and South Oakland, older apartment buildings in Shadyside and East Liberty, and restaurants and bars across the city are typical hot spots.
The American cockroach is much larger and reddish-brown. It lives in sewer lines and damp cellars and appears when it is humid or when water systems are disturbed. Pittsburgh's old combined sewer lines and stone-walled cellars suit it well. The Oriental cockroach, dark and shiny, hides in cool, wet crawlspaces and under leaky fixtures.
Signs of infestation
- Droppings that look like pepper or coffee grounds, near cabinet hinges and behind stoves.
- Egg cases stuck in dark crevices.
- A musty smell where numbers are large.
- Roaches running when you switch on a light, especially in the kitchen.
The professional approach
A provider inspects for species, hot spots and moisture sources, then selects a plan. For German roaches, gel baits and bait stations placed in cracks, with growth regulators to break the breeding cycle, are the core. Providers also seal gaps with caulk or fillers where roaches travel. For basement-dwelling species, treatment includes drains, foundation cracks, utility entry points and the building perimeter. Repeat visits are normal because egg cases hatch in waves.
In apartment buildings or duplexes, treat neighboring units simultaneously whenever possible. Otherwise roaches simply retreat next door and return.
Food service workers sometimes carry roaches home without knowing it, particularly in bags and shoes. Keeping a work bag on a hard surface, away from the kitchen and bedroom, helps. In Pittsburgh basements, where a laundry area often shares space with storage, moving boxes onto shelves and running a dehumidifier cuts down on the dampness that American and Oriental roaches prefer.
Practical changes at home
- Wipe counters and the stovetop nightly, and sweep crumbs.
- Store dry goods and pet food in airtight containers.
- Fix leaking taps and insulate sweating pipes.
- Remove piles of newspaper, bags and cardboard.
- Seal gaps around pipes, outlets and baseboards.
What landlords and tenants should know
Pennsylvania renters can ask the landlord for pest control, and written requests protect everyone. Tenants who cooperate by clearing cabinets and allowing access get faster results. Owners of multi-unit buildings in Pittsburgh benefit from scheduled inspections of all units, not just those with complaints.

Pittsburgh roach FAQ
Why are there roaches in my newly renovated apartment?
They can move in through shared walls and pipes, or arrive in belongings. Renovation doesn't remove them from adjoining units.
Do roaches need water to survive?
Yes. Fixing leaks and drying surfaces makes a difference.
Are roach sprays from the store effective?
Often not. Roaches avoid or become resistant to many sprays, and sprays can disperse them.
Can roaches trigger asthma?
Their droppings and shed skins are known allergens that can aggravate asthma, especially in children.
