Trapping without exclusion is a revolving door. We stop the problem permanently — seal every gap, eliminate the population, verify it's done.
📞 (703) 804-7057The wooded stream corridor running through Sterling functions as a highway for deer mice and Norway rats. Properties backing up to it have near-constant pressure from October through April.
The warehousing and food service operations along the Dulles corridor sustain large rodent populations that push into adjacent Sterling residential neighborhoods.
Sterling Park, Sugarland Run, and 1970s–80s construction have accumulated the gaps mice need. A mouse enters through a hole the diameter of a pencil. We find them all.
Mice gnaw electrical wiring inside walls — it's the leading cause of residential house fires in Virginia. This isn't a nuisance problem. It's a safety emergency.
If we trap inside your home without sealing entry points, you eliminate the current population and a new one moves in within weeks. Exclusion is the permanent fix. We inspect your entire foundation, roofline, utility penetrations, and garage connections — every gap larger than a quarter inch gets sealed with professional rodent-proof material before any trapping begins. Follow-up visits confirm the exclusion held and that no new activity is present.
Droppings along wall edges, in cabinets, or behind appliances. Gnaw marks on food packaging, cardboard, or wiring insulation. Greasy rub marks along wall bases where rodents travel. Rustling or scratching sounds in walls or ceiling — most active at night. Nesting material (shredded insulation, paper, fabric) in hidden areas. One or two signs means an established population is already present.
Rodent pressure in Sterling peaks in October and November when field mice and Norway rats migrate toward heated structures as temperatures drop. This is the most important window for preventive exclusion work — having us inspect and seal before cold weather arrives is far less expensive than dealing with an established winter population. Call us in September or October if you've had any previous rodent activity.
