House mice are among the most common indoor pests in America. They contaminate food, damage insulation, and reproduce rapidly. DIY mouse control depends on sealing entry points, eliminating food sources, and trapping.
Identification & Behavior
Mice are small, gray or brown rodents with pointed noses and long thin tails. They are curious, agile climbers and squeeze through openings as small as a dime.
Why Mice Enter Homes
Mice seek food, nesting material, and warmth. Crumbs, pet food, cardboard, wall voids, and seasonal temperature changes drive infestations.
DIY Prevention Methods
- Seal cracks and holes larger than ¼ inch
- Store food in airtight containers
- Vacuum crumbs and spills nightly
- Reduce storage clutter
- Install weather stripping
Natural & Non-Chemical Controls
- Snap traps placed along runways
- Peppermint oil deterrents (limited effect)
- Steel wool exclusion barriers
- Glue boards (monitoring only)
Store-Bought Control Options
- Pre-baited snap traps
- Multi-catch live traps
- Electronic traps
- Indoor bait stations
When to Call a Professional
If mice are active in walls, ceilings, or multiple rooms, professional sealing and trapping programs are strongly recommended.
