House mice are the most common indoor rodent in Dallas, and the one homeowners most often underestimate. The problem with mice isn't any single mouse — it's the math. A mouse can squeeze through an opening as small as a quarter-inch, and they breed fast enough that a small problem becomes a large one within weeks if left untreated.
Why mice are deceptively serious
- They breed fast. A few mice become an infestation in weeks — waiting is the most expensive choice.
- They fit anywhere. A quarter-inch gap is a doorway. Around pipes, under garage doors, at utility penetrations, through weep holes.
- They contaminate. Mice are incontinent as they travel, leaving droppings and urine across pantry shelves and food-prep surfaces — a genuine health and allergy issue.
- They chew. Like all rodents, mice gnaw constantly, including on wiring.
Signs of mice specifically
Small (rice-grain) droppings along walls and in drawers, faint scratching in walls at floor level, gnawed food packaging, and a musky odor in enclosed spaces. Mice tend to stay near food and shelter, so kitchens, pantries, garages and wall voids are the usual spots. Our signs guide has the full checklist.
Why DIY often falls short with mice
A single trap can catch a single mouse. The trouble is that by the time you see one, there are usually more, and hardware-store efforts almost never seal every quarter-inch entry point — so the population rebuilds from the gaps you missed. Effective mouse control is trapping to clear the active population plus exclusion to seal the entry points, including the weep holes in brick homes.
Our approach
- Inspection — find where mice are entering and nesting.
- Trapping & removal — clear the current population quickly, before it multiplies.
- Exclusion — seal quarter-inch gaps, weep holes and utility penetrations.
- Sanitation guidance — safe droppings cleanup (never dry-sweep).
Safety note on cleanup
Never sweep or vacuum mouse droppings dry — disturbing them releases contaminated particles. Soak with disinfectant, let it sit, then wipe. For larger accumulations, wear gloves and a mask, or have it handled professionally.
Because mice multiply so fast, early action is genuinely cheaper. Book a free inspection today. Larger rats behave differently — see rat control.
