Dundalk is a working-class community in southeastern Baltimore County, built on the Patapsco River estuary around the industrial waterfront and the Sparrows Point steelworks. Its pest pattern is shaped by old housing and proximity to tidal water. Dundalk's stock is largely older, much of it built for the steel and shipyard workforce in the early to mid-20th century, with the settled foundations, wood close to grade, and accumulated gaps that age brings. That makes the community a heavy subterranean termite and rodent zone. The waterfront location on the Patapsco estuary puts homes near tidal areas, marshy edges, and storm drainage, which drives high mosquito activity through the long warm season. Norway rats are an established problem in the older neighborhoods, where dense housing and aging infrastructure give them cover. The estuary's humidity keeps moisture-pest pressure up year-round.
Common pests in Dundalk
The pests Dundalk homeowners deal with most. Tap any one for identification and treatment details.
Subterranean Termite
The most destructive wood-destroying insect in North America. It lives underground and attacks wood from below, invisibly, for years before homeowners notice.
Read moreNorway Rat
The large, burrowing rat found near foundations, dumpsters, and sewer lines. Norway rats cause serious structural damage and carry diseases that pose real health risks.
Read moreMosquito
Blood-feeding flies that breed in standing water. Several species in the Upper Midwest and Mid-Atlantic carry West Nile virus, and one imported species bites aggressively during the day.
Read moreHouse Mouse
The most common rodent in homes year-round. Small, fast, and capable of squeezing through a gap the width of a pencil, house mice nest inside walls and breed quickly.
Read moreAmerican Cockroach
The largest common house cockroach, reddish brown and nearly two inches long, mostly found in basements, drains, and commercial buildings.
Read moreCarpenter Ant
A large black ant that excavates wood to nest. It does not eat the wood, but a long-established colony can cause real structural damage.

Pest pressure in Maryland shifts hard with the seasons, from spring termite swarms to the long Chesapeake mosquito season and the fall stink bug invasion. This is the rough arc of the year, so you know what tends to show up when.
| Month | Pressure | Most active | What to watch |
|---|---|---|---|
| Jan | Low | Mice, Rats, Cockroaches, Stink bugs | Rodents stay indoors for warmth. Overwintering stink bugs stir on warm windows. |
| Feb | Low | Mice, Rats, Overwintering invaders | Quiet month. Indoor rodent activity continues and overwintering pests move on mild days. |
| Mar | Moderate | Termites, Ants, Stink bugs, Ticks | Termite swarm season begins as the coastal plain soil warms. Stink bugs re-emerge. |
| Apr | High | Termites, Carpenter ants, Mosquitoes, Ticks | Termite swarms build. Mosquito season opens and ants begin foraging in earnest. |
| May | High | Termites, Mosquitoes, Ants, Ticks | Termite season closes out. Mosquito and tick pressure climbs hard across the watershed. |
| Jun | High | Mosquitoes, Ants, Wasps, Ticks | Full summer pressure. Asian tiger mosquitoes bite all day and stinging insects expand. |
| Jul | High | Mosquitoes, Cicada killers, Wasps, Spiders | Mosquito season peaks. Cicada killers dig lawn burrows in the summer heat. |
| Aug | High | Mosquitoes, Yellowjackets, Spotted lanternfly, Fruit flies | Mosquitoes still heavy. Yellowjacket colonies turn aggressive and lanternfly adults appear. |
| Sep | High | Stink bugs, Spotted lanternfly, Yellowjackets, Mosquitoes | Fall invasion begins. Stink bugs mass on warm walls and lanternfly swarms exterior surfaces. |
| Oct | High | Stink bugs, Spotted lanternfly, Mice, Camel crickets | Peak structural intrusion. Stink bugs push into wall voids and rodents start moving indoors. |
| Nov | Moderate | Mice, Rats, Overwintering invaders | Rodents push indoors ahead of hard cold. Stink bugs settle into wall voids and attics. |
| Dec | Low | Mice, Rats, Cockroaches | Rodents seek heated structures. Cockroach and bed bug activity continues indoors. |
Maryland's mild winters rarely kill off overwintering pest populations, so the active season runs long. Treat this as a guide, not a fixed schedule.
When to call a Dundalk exterminator
In Dundalk, the old housing and the waterfront set the pest calendar. Termites deserve real attention: the early to mid-20th-century homes have old wood framing close to grade, and Maryland's heavy pressure makes confirming protection important. Any mud tube or spring swarm warrants a quick inspection. For rats, watch for burrows along the foundation, the garage slab, and the alleys, and call before a colony grows, since the dense older neighborhoods give them cover. Mosquitoes build hard off the Patapsco estuary tidal areas and marshy edges from April on, so a seasonal program before summer keeps the yard usable. American cockroaches come up from drains and damp basements, which points to a moisture problem. Rodents push indoors as the weather turns cold.
