Mouse and Rat Control

House mice and Norway rats are two different problems and need two different plans. Mice are an interior harborage problem: they nest inside wall voids, under kitchen cabinets, behind ranges and in stored boxes, and they can slip through an opening the width of a pencil — dryer vents, the corner gaps under a garage door, gaps where the water line or gas line passes through a block foundation. Norway rats are an exterior burrowing problem first: they dig along fence lines, under sheds and concrete stoops, and beside sewer cleanouts, then push in at slab edges and utility chases. A single interior spray or a handful of snap traps placed without a perimeter walk will not solve a rat burrow twelve feet from the back door.

District Heights housing stock makes both realistic. Many of the brick homes off Marbury Drive near the Municipal Center and through Coral Hills were built in the 1950s and 60s, and older mortar joints, crawlspace vents and add-on porches give mice several inches of unsealed entry to work with. Shared-wall duplexes and the Donnell Drive apartment blocks add a second issue: rodents travel through common walls, joist runs and plumbing chases, so one clean unit sitting next to an untreated unit will re-infest. Alley dumpster pads behind the Marlboro Pike commercial strip, the Penn Mar Shopping Center area in Forestville, and the food waste along the Silver Hill Road corridor support rat populations that spill into nearby yards, and the stream and storm-drain corridors near Walker Mill Regional Park give rats cover to move block to block. Late fall — the first real cold snap in Prince George's County — is when interior mouse calls climb sharply.

On deciding between a one-time rodent job and a maintained program: a one-time visit fits a single mouse that came in through a known, fixable opening, in a house with no droppings in more than one room. A maintained program with monthly or quarterly exterior monitoring fits rats, repeat mouse activity, restaurants-adjacent properties, and rental buildings where tenant turnover keeps reopening the risk. The trade-off is honest — one-time work is cheaper and can be enough, but it puts the burden of the sealing on you if you decline the exclusion portion. No rodent job is finished until the entry points are closed, so if exclusion is out of budget this month, we will list the openings in priority order and you can do them yourself or stage them.

Safety questions get straight answers. Rodenticide, when used, goes in locked tamper-resistant stations placed where a toddler or dog cannot reach the bait; in homes with children, pets, or a resident who feeds outdoor cats, we can run the job on traps and exclusion only. We will show you the product label and the re-entry time before anything is placed. We will not put you into an annual contract to solve a two-visit mouse problem — if quarterly service is the right call for your building, we will explain what changes and what it covers, and you can say no. Identified first. Treated right. Verified gone.
