The Most Common Summer Pests in Baltimore, MD

Baltimore's summer pest picture is shaped by stink bugs, roaches in the urban core, and rodents pushing into the city's older housing stock. Roaches are the one that varies most by neighborhood, since rowhouse density and shared walls make it easier for an infestation to spread between adjoining units.

Stink Bugs

Stink bugs show up across the Baltimore suburbs the same way they do throughout Maryland, clustering on light-colored, sun-exposed exteriors before pushing indoors as temperatures cool later in the season.

Roaches

Roaches, particularly German roaches, are more of a year-round urban-core issue than a strictly summer one, but summer humidity accelerates their reproduction cycle. Shared walls and older plumbing in Baltimore's rowhouse neighborhoods mean an infestation in one unit is a real risk to neighboring units.

Rodents

Rodents favor Baltimore's older housing stock, where aging foundations, gaps around utility lines, and mature urban tree cover give mice and rats more access points than newer suburban construction. Exclusion and sealing gaps around the foundation line matters more here than in newer-built markets.
