Pest Control in District of Columbia

Washington, D.C. is a city of row houses and brick apartment buildings, of the underground metro tunnels and the alleyways where the trash builds, of the Potomac and the Anacostia rivers and the green spaces of Rock Creek Park and the National Mall. The pest control here is urban pest control, shaped by the density of the rowhouses, the age of the building stock, the underground infrastructure that the rats travel through, and the river corridors that the mosquitoes and the stink bugs follow. The District’s humid subtropical climate — hot and humid in the summer, mild in the winter — keeps the pressure running through most of the year.

The Norway rat is the headline pest in D.C. The city’s underground metro system, its alleyways, and its aging sewer infrastructure give the rats a network that covers every neighborhood. The row houses of Capitol Hill, Georgetown, and Dupont Circle sit on the clay-based soil that holds moisture, and the shared walls, the basements, and the aging foundations give the rats and the mice routes through the entire block. The German cockroach, the bed bug, and the subterranean termite are the top insect calls, and the mosquitoes and the stink bugs follow the river corridors and the green spaces.

The pests that matter in D.C.

• Norway rats and house mice — the dominant rodent pressure. The rats work the alleyways, the metro corridors, and the underground utility spaces; the mice follow the food and the warmth in the row houses and the apartment buildings.
• German cockroaches — the top indoor insect pest in the multi-unit buildings and the older row houses, especially the buildings with the shared walls and the common plumbing.
• Bed bugs — a recurring issue in the city’s dense housing stock, the rental market, and the hotel and travel corridors. The turnover in the apartment buildings and the student housing keeps the pressure present.
• Subterranean termites — the eastern subterranean termite is active in the District, and the clay-based soil holds the moisture against the foundations of the older row houses and the brick buildings.
• Mosquitoes — the Potomac and the Anacostia river corridors, Rock Creek Park, and the city’s green spaces all support the mosquito population through the warm months.
• Stink bugs and boxelder bugs — the fall invaders that cluster on the warm, sunny walls of the row houses and the apartment buildings and work their way in through the gaps.
• Ants — the pavement ants, the odorous house ants, and the carpenter ants in the older, moisture-prone buildings.

The D.C. pest calendar

• March to May — the termite swarm season peaks after the warm rain; the ant activity builds; the mosquitoes start breeding in the standing water.
• June to August — the heat and the humidity drive the cockroach, the ant, and the mosquito pressure; the wasps and the hornets build around the eaves and the balconies.
• September to November — the stink bugs and the boxelder bugs cluster on the sunny walls; the rodents start moving toward the warm structures as the weather cools.
• December to February — the indoor rodent pressure peaks; the cockroaches and the spiders stay active in the heated buildings.
• Year-round — the bed bugs in the rental and the travel corridors, and the rats and the mice in the underground infrastructure.

How we work in D.C.

Every D.C. job starts with a free inspection by a licensed technician who knows the city’s neighborhoods and its building stock. The rodent exclusion that keeps the rats and the mice out of the row houses and the apartment buildings is the foundation of most D.C. plans, and the cockroach and the bed bug treatments are built around the density and the shared walls of the city’s housing. The quote is written before any product goes down, and the treatment is matched to the building, the block, and the actual pressure on the property.

If you are in Capitol Hill, Georgetown, Dupont Circle, Adams Morgan, Columbia Heights, Shaw, Navy Yard, or any of the neighborhoods across the District, a local technician is ready to walk your property, map the real pressure, and quote the work honestly.
