From Capitol Hill row houses with shared party walls to NoMa and Navy Yard high-rises, Eco Pest Controls handles the rats, roaches, termites, and bed bugs that come with living close together in a dense, century-old city.
Washington's housing stock is unusually old and unusually attached. Long blocks of rowhouses share party walls, joist bays, and pipe chases, so a rat or roach problem rarely stays confined to one address — it moves door to door down the block. Many neighborhoods still rely on rear service alleys for trash collection, which gives rodents a reliable, sheltered food source year-round rather than just during warm months.
The climate doesn't help. Humid, sticky summers followed by mild, wet winters keep termites active for most of the year and give German cockroaches ideal breeding conditions in older kitchens and shared building risers. Add in a transient population — students, Hill staffers, and short-term federal employees cycling through leases every one to two years — and bed bugs travel between units faster here than in most cities.
Each of these shows up differently depending on whether you're in a rowhouse, a mid-rise, or a rooftop unit — our technicians treat all three.
D.C.'s alley-and-rowhouse layout gives rodents cover and a steady food supply. We combine exterior baiting, burrow treatment, and exclusion work — sealing the gaps around dryer vents, foundation cracks, and rowhouse crawlspaces where rats actually get in — rather than just setting traps indoors.
Common in older kitchens, shared plumbing risers, and multi-unit buildings where roaches move between apartments through wall voids. Gel baiting and IGR (insect growth regulator) treatment work better here than sprays, which just scatter an existing infestation into neighboring units.
The Mid-Atlantic's humidity keeps termite colonies active nearly year-round. Older rowhouses with original wood framing and detached garages are especially exposed — we inspect for mud tubes and moisture damage and can set up liquid or bait-station treatment without disturbing historic woodwork.
High tenant turnover and close-quarters apartment living make bed bugs one of the most common calls we get in D.C. rentals. We treat with a combination of heat and targeted chemical application, and can coordinate with property managers when an infestation spans more than one unit.
Mature street trees and rowhouse cornices give wasps and yellow jackets plenty of places to nest close to entryways. We remove active nests and treat likely return spots before the next season starts.
The right treatment plan depends on your building type as much as your address — here's what we typically see in each area.
Dense rowhouse blocks with shared walls — rat and mouse pressure moves fast from house to house.
Older brick and wood-frame construction near the waterfront, with real termite and carpenter ant exposure.
Mixed rowhouses and pre-war apartment buildings; recurring roach and rodent calls in shared basements.
High restaurant density brings extra rodent pressure to nearby residential blocks and alleys.
Larger rowhouses converted into multiple rental units — a common bed bug and cockroach pattern.
Newer high-rise construction with fewer structural gaps, but still real rodent activity around loading docks and dumpsters.
Older single-family and small multi-unit housing east of the river, with typical rodent and termite exposure.
Office and mixed-use density — commercial accounts alongside residential high-rises.
One-time visits or quarterly plans for rowhouses, apartments, and single-family homes.
Baiting, trapping, and physical sealing of the entry points rats and mice actually use.
Liquid and bait-station options suited to older wood-framed construction.
Heat and targeted chemical treatment, with multi-unit coordination when needed.
Gel baiting and IGR treatment built for shared-wall buildings, not just single units.
Restaurants, offices, and multi-family properties across the District.
Under the District's Tenant Bill of Rights, landlords are required to keep rental units and common areas "safe and secure and free of rodents and pests," and D.C.'s Bedbug Control Act places the responsibility for treatment on the landlord in most multi-unit buildings — it generally shouldn't fall on the tenant to pay for an exterminator when the infestation isn't confined to one unit or one person's doing.
We work directly with both property managers and individual renters, and can provide the kind of documented treatment report that's often needed if a landlord dispute goes to the DC Office of the Tenant Advocate or a housing code inspection.
This is general information, not legal advice. For a specific dispute, the DC Office of the Tenant Advocate or Office of the Attorney General's Office of Consumer Protection can advise on your situation.
Tell us what you're seeing and where — rowhouse, apartment, or commercial space — and we'll put together a plan before we quote you anything.
Rats and mice, German cockroaches, subterranean termites, bed bugs, and seasonal wasps are the calls we get most, largely driven by the city's dense rowhouse blocks, shared walls, and humid climate.
In most multi-unit buildings, yes — D.C.'s Tenant Bill of Rights and the Bedbug Control Act place responsibility on the landlord for common areas and for infestations that aren't confined to a single tenant's unit. Specific disputes should go through the DC Office of the Tenant Advocate.
Shared party walls and joist bays let rodents and roaches move freely between attached units. Treating one house in isolation often just pushes the problem next door and back again — a building-wide or block-aware approach holds up much better.
No — we use targeted baiting and exclusion methods designed for historic construction rather than broad drilling or spraying, and we'll flag anything that needs a lighter touch before we start.
One-time treatments typically run $150–$350 depending on the pest and property size, and quarterly plans average $80–$150 per visit. Every job starts with a free on-site inspection so the quote reflects your actual property, not a flat rate.
