Maryland sits in the middle of the eastern subterranean termite's range, and Baltimore's historic housing offers them plenty of wood. Row homes in Charles Village, Highlandtown, Remington and Ridgely's Delight have timber joists, wood floors and window frames sitting on brick or stone foundations. Free-standing houses in Roland Park, Hamilton and Lauraville often have wooden porches and additions. If any of these have had a leak, a poor drainage setup or a history of renovation, they are candidates for termite activity.

The termite behind the damage
Eastern subterranean termites live in the soil and travel through mud tubes to feed on wood above. Colonies swarm in spring, and the winged adults can show up inside the house around windows or in a basement. Maryland's winters slow but do not stop them near heated foundations. Drywood termites are not the normal concern in Baltimore. Instead, the concern is soil contact, hidden moisture and shared walls that provide continuous wood-to-ground paths between neighboring homes.
Why row homes need special care
When termites enter one row home, their tunnels can follow shared joists and walls into the next. A treatment on a single house may leave an untreated neighbor who then re-infests it. Many row homes also have rear additions, wood decks and cellar stairs where wood meets earth or damp masonry. Flat roofs and leaky parapets create persistent moisture inside upper walls. Because the brick exterior hides what is happening inside, an inspection that includes the cellar, the first-floor framing and the rear addition is a must.
Warning signs
- Mud tubes on cellar walls or on the sill beams.
- Swarming winged insects inside the house in spring.
- Floors that feel soft or bouncy, or baseboards that crumble.
- Doors and windows that no longer close properly.
- Small holes in drywall with a hollow sound when tapped.
Treatment options
- Soil treatment along the foundation, which can include drilling through cellar floors and porch slabs.
- Bait systems placed in the ground around the house or in the rear yard.
- Targeted foam or wood treatments in localized infestations.
- Moisture correction such as repairing gutters, flashing and downspouts.
- Documentation for buyers, lenders or association boards.
In attached homes, ask your provider whether neighboring properties should be checked and how to communicate with them.
Lowering your odds
- Fix leaks promptly, especially on roofs and rear additions.
- Keep firewood and construction scraps away from the house.
- Clear soil and mulch from touching wood.
- Maintain gutters and extend downspouts.
- Arrange regular inspections in older homes.

Baltimore termite FAQs
Do termites live in brick houses?
Yes. The brick is not the problem; the wood inside it is. Termites reach it through foundations and mortar cracks.
Should a landlord pay for termite treatment?
That depends on your lease and local rules. Notify them in writing.
What do swarms look like?
Dozens of winged insects, often near light or a window, with wings that drop off afterward. You may find the wings in piles.
How often should I have a termite inspection?
Many providers recommend an annual check for older properties or those with a past infestation.
