Pest Control in Maryland

Maryland pest pressure, metro by metro

Maryland does not have one pest problem — it has one per metro, shaped by local weather:

• humid summers and cold winters that swing pressure between termites, ticks and overwintering invaders (Baltimore)
• humid summers and cold winters that swing pressure between termites, ticks and overwintering invaders (Hagerstown)
• humid summers and cold winters that swing pressure between termites, ticks and overwintering invaders (Lexington Park)

Across the state we cover 15 counties within these metro areas. Browse the metro pages below, or see the Maryland county index for county-level coverage.

Maryland coverage in numbers

Add the state up and coverage looks like this: about 3,384,237 people across 3 metro areas, 42 named communities, 233 ZIP codes and 15 counties — with Baltimore, the largest metro, carrying roughly 84% of the covered population. Annual average temperatures span from about 54°F around Hagerstown to 59°F around Baltimore, a spread that moves first-frost dates, termite pressure and tick seasons from one end of Maryland to the other.

The housing stock writes the rest of the story. In Baltimore, the largest metro, about 56% of homes predate 1980 and the median home was built in 1975 — older framing, older voids, and the pest profile that comes with them. Owner-occupiers make up about 67% of households there, which is why the metro guides speak to homeowners planning inspections and programmes, not one-off visits alone.
