Maryland pest control: common pests, seasons & local options
From the star-shaped ramparts of Fort McHenry to the shores of the Chesapeake, Maryland's waterways and humidity shape its pest life. Baltimore, Columbia, Germantown, Silver Spring, and Annapolis homeowners battle termites, marsh mosquitoes, ticks, and famous fall invasions of stink bugs.
Most common pests in Maryland
The four pest problems Maryland homeowners ask about most — and what drives them locally.
Termites
Maryland's humid Chesapeake climate supports heavy subterranean termite pressure, especially in older Baltimore rowhomes and suburbs.
Mosquitoes
Chesapeake Bay marshes breed fierce mosquito populations that press on Maryland backyards from May through October.
Stink Bugs
The brown marmorated stink bug — first U.S. invasion traced to nearby Pennsylvania — swarms Maryland homes every fall.
Ticks
Lyme-carrying blacklegged ticks are widespread in Maryland's suburbs and wooded parks from spring through fall.
Pest seasons in Maryland
Maryland's pest year opens with spring termite swarms and tick season, peaks with Chesapeake mosquitoes and stinging insects through summer, and turns in October when stink bugs and mice head indoors. Humid summers keep crawling pests active well into November.
