Baltimore is a city of brick row homes, many of them a century old and connected for entire blocks. In neighborhoods from Fells Point and Canton to Hampden, Federal Hill and Pigtown, the same wall may be shared by three or four houses, and that is the root of most local pest problems. Combined with a working harbor on the Patapsco, a humid mid-Atlantic climate and a long history of alleys and shared trash areas, the city gives pests plenty of room to move.

The pests Baltimore residents see
- Norway rats in alleys, trash areas and the foundation walls of row homes.
- House mice living inside shared walls and basements.
- German cockroaches in apartments and restaurants, and American cockroaches in basements and sewer-adjacent areas.
- Eastern subterranean termites in wood floors, joists and door frames.
- Odorous house ants and pavement ants in kitchens and along sidewalks.
- Bed bugs in rentals, hotels and student housing near the universities.
How row home construction affects pests
Row homes share party walls, so a pest that enters one house can move along the wall, along pipes or through the cellar to its neighbors. Many row homes have brick or stone cellars with dirt-like floors or aging concrete, formstone or brick exteriors with weathered mortar, and flat roofs with parapets that trap water. Back alleys serve as shared service areas where trash cans, dumpsters and yard debris gather. All these features give a pest professional a map of where to look, and they explain why neighbors often need to work together.
Climate and seasons
Baltimore summers are hot and humid, which supports roach and mosquito activity and encourages ants to look for water indoors. Winters are cold enough to drive rodents inside but not cold enough to stop indoor pests. Spring swarms of termites and ants are typical, and the city's proximity to the Chesapeake Bay keeps humidity elevated for much of the year.
What a visit typically involves
- Inspection of the basement, kitchen, bathrooms, rear yard and the alley behind the house.
- Identification of pests and entry routes, including shared-wall pathways.
- Treatment with baits, traps, residual products and sealing as appropriate.
- Recommendations that involve neighbors or landlords where needed.
- Follow-up visits tailored to the pest.
Prevention for city homes
Keep trash in lidded containers and place it out on collection day. Seal gaps around pipes with steel wool and caulk. Maintain basement windows and doors. Repair rotting back doors and thresholds. Avoid storing cardboard in cellars. If you rent, report problems promptly in writing so your landlord can coordinate service with neighbors.

Baltimore pest questions
Why do pests keep coming back in my row home?
Often because the source is a neighboring home or a shared wall. Coordinating with neighbors usually gives better results.
Are rats common in Baltimore?
Rats are a known issue in the city, particularly near alleys and food businesses, so sanitation and exclusion are important.
Do I need a termite inspection when buying a row home?
It is wise. Wood floor joists and sills in old row homes can be vulnerable.
Can the city help with pest problems?
The city handles some public-area issues such as trash and rat complaints. A private provider handles treatment inside your property.
