Mouse Removal & Control in Plano, TX

House mouse caught near a kitchen baseboard gap in a Plano, TX home

A house mouse can flatten its body enough to fit through a gap about the diameter of a dime, and on a slab-on-grade home that gap is almost never where you'd expect. We find them most often around garage door thresholds that have lost their seal in the heat, gaps where a utility line or hose bib penetrates the slab, and weep holes along the brick veneer that were never screened — all common on both older Plano homes near downtown and newer builds in west Plano, since a production framing crew moves fast and doesn't always catch every small opening at final inspection, even on a house finished within the last two or three years.

Mice reproduce roughly every three weeks, so a few droppings behind the stove in September can be a real infestation by the time the weather cools in November — which is exactly when we see calls spike, as Plano's shorter cold snaps push mice indoors looking for warmth and an easy food source. But because our winters rarely stay cold for long, mouse pressure here doesn't fully die back the way it might elsewhere; a house that's tolerant of them can carry a population through most of the year, with fall simply being the busiest stretch on our schedule rather than the only one.

Our process starts by finding every active entry point, not just the first one we spot, since a mouse population will use more than one route into the same house, particularly once numbers grow past a handful of animals. We combine targeted trapping — placed on the actual travel paths, not scattered at random through a kitchen or garage — with exclusion using steel mesh and appropriate sealant rather than foam alone, which mice chew through without much effort and often within the first week.

Mice also carry a real health-and-property angle beyond the nuisance factor: they contaminate stored food, shred insulation and cardboard for nesting material, and their urine and droppings can trigger allergy symptoms in a household, particularly for kids. A single breeding pair left unaddressed for a full season can realistically produce dozens of descendants, which is why a problem that looks minor in October can be a genuinely large one by the following spring if it's left alone rather than addressed early.

You'll get a written report of what we found and sealed, plus a follow-up check to confirm activity has genuinely stopped rather than simply gone quiet. Call (305) 501-6723 for a free inspection.

Where Mice Get Into a Plano Slab Home

Because there's no crawl space to breach, mice work the slab edge and roofline just like rats do, only through smaller gaps most homeowners would never notice without looking closely. The most common entry points we find are garage door seals that have shrunk or warped in the heat, unscreened weep holes along brick veneer, gaps around a dryer vent or hose bib penetration, and the narrow seam where a garage-to-house wall meets the slab. New construction in west Plano and nearby Frisco isn't automatically safer — production crews routinely leave a plumbing stack or HVAC line-set penetration uncaulked, and it's often the very first gap a mouse finds, sometimes within the home's first year. We've also found mice entering through gaps around a newly installed pet door, an aftermarket dryer vent flap that doesn't seal fully, and a garage service door that was never weatherstripped at the bottom corner.

Signs of a Mouse Infestation

Mice leave smaller, more numerous droppings than rats — usually clustered behind appliances, inside pantry cabinets, or along the garage baseboard, often in a scattered pattern rather than a single pile. You'll also see light gnaw marks on cardboard food packaging, shredded paper or fabric tucked into a nest behind an appliance or inside a garage storage box, and a faint musky odor in an enclosed space like a cabinet toe-kick that gets stronger the longer a nest has been active. Mice are neophobic, meaning they're wary of new objects, so scratching sounds at night — especially behind walls near the kitchen — often show up before any visual sign does, which is why a lot of homeowners hear a problem for weeks before ever finding proof of it. A dog or cat pawing persistently at a cabinet base is frequently the first real clue, well before a human notices anything.

Targeted Trapping, Not Guesswork

We place snap traps and, in homes with small children or pets, enclosed tamper-resistant stations directly on the paths mice are actually using — against walls, behind the refrigerator and stove, inside cabinet voids near plumbing. Because mice are cautious around unfamiliar objects, placement matters more than trap count, and we revisit and reposition based on where fresh activity is actually showing up rather than leaving traps in the same spot regardless of results, since a placement that worked on visit one can go cold once the surviving mice learn to route around it. We also check bait stations more frequently than a typical rat program, since mouse populations turn over faster and a station left unchecked for two weeks can miss most of the activity that happened in between.

Sealing Gaps for the Long Term

Spray foam alone doesn't hold against mice — they chew through it in a night, sometimes less, and a foam-only seal can actually make a homeowner think a gap is closed when it's really just temporarily plugged. We use stainless steel wool paired with an appropriate sealant, copper mesh, or hardware cloth depending on the gap and material, whether it's an older brick home near Haggard Park or a two-year-old townhome off the Dallas North Tollway. Every utility penetration, weep hole, and garage seal we touch is treated the same way, so the seal actually lasts through Plano's heat and clay-soil movement rather than just buying a few weeks before mice find the same spot again.

Fall Increase and Year-Round Baseline

Mouse calls climb through October and November as nights cool and mice look for warmth and an easy food source indoors, but because Plano winters rarely stay cold for long stretches, activity here doesn't drop off the way it does farther north — a mild January thaw is enough to keep a population active straight through what would be a dead season elsewhere. That means a mouse problem can quietly build across most of the year rather than showing up only in one predictable season, which is part of why we recommend an exclusion check any time of year activity is suspected, not just in fall when everyone else is calling. Summer brings its own smaller bump too, as mice follow the same water-seeking behavior that drives rats indoors during the hottest stretches.

Mice in Garages, Pantries & Storage Areas

Beyond the kitchen, Plano garages are a favorite mouse habitat — stored cardboard boxes, pet food bags, and clutter along the walls give them cover and nesting material within a few feet of an easy exterior entry point at the door threshold. Pantries and any built-in cabinetry near an exterior wall are the next most common spot, particularly where dry goods are stored in their original cardboard or paper packaging rather than a sealed container. We inspect all three areas specifically on every mouse call, since a homeowner focused only on the kitchen sink area can miss an active nest sitting in a garage storage bin a few feet away. Attics get checked too, even on a mouse call, since mice will nest there just as readily as a rat or squirrel if the roofline offers any access at all, particularly in homes where the garage attic connects directly to the main attic space above the living area.

What Mouse Control Typically Costs

Cost depends mainly on how many entry points need sealing and whether the population is fresh or already established across multiple rooms — a single gap around a utility line with light activity costs considerably less to resolve than a spread-out infestation touching the kitchen, garage, and a bedroom closet. We quote trapping and exclusion as separate line items based on what the inspection actually finds, rather than a flat per-visit rate that doesn't reflect the real size of the job in front of us.
