Winter is peak mouse season, and if you're reading this, you've probably already noticed the signs: scratching at night, droppings in the kitchen, that musty smell you can't quite place.
Here's what I tell every homeowner I visit from Fairfax to Alexandria: if you're seeing one sign of mouse activity, there are more mice hiding where you haven't looked.
After fifteen years in rodent control throughout Northern Virginia, I've learned that the difference between a minor nuisance and a full infestation comes down to how fast you act.
Why Mice Move In During Winter
Once temperatures drop, mice aren't visiting—they're settling in for good. Your house offers warmth, food, and protection from predators. Everything they need.
The math gets ugly fast: a single breeding pair produces 60+ offspring per year. That scratching you heard last week? Without intervention, it's a serious problem by February.
And mice only need a gap the size of a dime to get inside. The space around your dryer vent or where your AC line enters the wall? That's an open door.
Signs You've Got a Mouse Problem
Here's what our technicians look for during inspections:
- Droppings — Small, dark, rice-sized pellets near food sources or along walls
- Gnaw marks — On food packaging, wood trim, cardboard, electrical wiring
- Grease tracks — Dark smudges along baseboards from repeated travel
- Scratching sounds — Especially at night, inside walls or ceilings
- Ammonia odor — Strong smells mean heavy activity
Spotted any of these? Don't wait for the population to multiply. Call 703-665-4455 for a same-day inspection and mouse control.
Where Mice Actually Hide
Homeowners are often surprised by where we find the worst mice infestations. Mice don't nest in obvious places.
Kitchen voids — Not the pantry, but behind dishwashers, under cabinets, and in wall cavities accessed through gaps around plumbing. That mouse you see in the kitchen may also be living somewhere else nearby in your home.
Attic insulation — Warm, quiet, undisturbed. Blown-in insulation is perfect for tunneling, and stored cardboard makes ideal nesting material.
Wall cavities — Mice treat your home's framing like a highway. Older homes in Arlington, Alexandria, and Falls Church often have gaps around electrical and plumbing penetrations that mice exploit for years before anyone notices.
Garages — Many infestations start here. Worn door seals and utility penetrations provide easy access, and pet food storage keeps them fed.
Basements and crawl spaces — Moisture, clutter, and direct routes to HVAC lines make these areas prime territory.
Why DIY Usually Fails
Snap traps catch mice. But catching a few isn't the same as solving the problem.
You can't find all the entry points. You seal one gap while five others stay open.
Placement matters. Mice travel along edges, not through the middle of rooms. Wrong placement means wasted effort.
DIY treats symptoms. Unless you eliminate the entire population AND seal every entry, mice keep returning—and breeding.
I've seen homeowners spend months catching one or two mice while the colony behind their walls keeps growing. By the time they call us, the minor problem has become a major one.

Common Questions
How fast can you get here? Same-day and next-day appointments are often available throughout Northern Virginia, Maryland, and D.C.
How long until the mice are gone? Treatments start working immediately. Complete elimination typically can take a few weeks depending on severity.

We have children and pets ourselves, and do not want to do anything in your home that would endanger your family. Not doing anything can be more harmful to your family since mice can spread many pathogens and diseases.
