Can Mice Get In Through The Floor? Hidden Entry Points You Should Know
Can mice get in through the floor? If you are hearing scratching beneath your feet or finding droppings in places that do not make sense, you might be wondering.
The answer might surprise you. Mice are excellent climbers and chewers, making even the smallest cracks and gaps viable entry points.
In this article, we will uncover how mice can sneak in through your flooring, what signs to watch out for, and how to protect your home from these persistent pests.
Can Mice Get in Through the Floor?
Can mice get in through the floor? Yes, mice can get in through the floor.
These crafty rodents are capable of squeezing through openings as small as 1/4 inch, and they are not shy about chewing through materials like wood, plastic, drywall, and even soft concrete.
If your home has crawl spaces, basements, or wood flooring with gaps, it may be more vulnerable than you think.
Understanding the entry points beneath your feet is crucial for full-proof pest control. Mice often exploit structural weaknesses or utility access points beneath the house to gain entry.

Common Floor Entry Points for Mice
- Crawl spaces: If your home has a raised foundation, mice can nest and enter through vent gaps or cracks in the crawl space.
- Plumbing and HVAC gaps: Pipes and air ducts that run through the floor often leave just enough space for a mouse to squeeze in.
- Gaps around floorboards: Especially common in older homes where wooden floors may warp or separate.
- Damaged or soft concrete: Mice may gnaw through deteriorated concrete in basements or foundations.
- Rodent tunnels: Outdoors, mice can burrow near foundation walls and slip in through gaps under floors.
Signs Mice Are Coming in Through the Floor
Here are some telltale signs mice may be entering your home from below:
- Scratching or scampering noises at floor level, especially at night.
- Mouse droppings in cupboards, along floor edges, or under appliances.
- Chewed or frayed materials near baseboards or floor vents.
- A musky odor in enclosed spaces like under the sink or cabinets.
- Visible gnaw marks on floorboards or pipes.
How to Prevent Mice from Entering Through the Floor
Now that you know mice can get in through the floor, prevention is the next step. Here is what you can do:
1. Seal Entry Points
Use steel wool and caulk or expanding foam to block holes near plumbing, ductwork, or foundation gaps. Mice cannot chew through metal easily.
2. Repair Damaged Flooring
Fix warped or broken floorboards and seal gaps. Inspect for signs of gnawing or wear and reinforce with rodent-proof materials.
3. Maintain the Crawl Space or Basement
Install mesh vent covers, keep the area dry, and remove debris that could provide nesting materials. Periodically inspect for signs of intrusion.
4. Install Floor Traps
Place traps or bait stations in areas where mice activity has been noticed. This helps catch invaders and monitor infestations.
5. Landscape Management
Trim shrubs and remove leaf piles near the foundation. Keep mulch and woodpiles away from exterior walls to prevent outdoor nesting near floors.

Are Certain Floor Types More Vulnerable?
Yes, some floors are easier for mice to penetrate:
- Wood Floors: Gaps and shrinkage make ideal mouse routes.
- Old Tiles: Cracked or missing grout offers access to subfloor layers.
- Vinyl Flooring: While durable, mice can lift or chew seams to get under.
- Carpet: Mice can burrow under the padding and move unseen beneath furniture.
Why it is Important to Act Quickly
Ignoring a mouse entry point through the floor could result in fast multiplication of rodents in your home. Mice reproduce quickly and often build nests near food sources.
In addition to chewing on wires, they can spread diseases through their droppings and urine.
Blocking floor access prevents infestations and protects your home from costly repairs and health risks.
Professional Help for Mouse Infestations
If you suspect mice are entering through your floor and DIY efforts haven’t worked, it’s time to call in a pest control expert. Professionals can use infrared detection, baiting systems, and exclusion techniques to stop mice at their source.
