How to Tell If You Have Mice in Your Walls – And What to Do About It in Boston Homes

If you're hearing odd scratching sounds at night or noticing small black droppings around your kitchen or basement, you might be dealing with mice—and they could be living inside your walls. In cities like Boston, where many homes are older with small cracks and crevices, rodent infestations are a common issue, especially during colder months.

In this post, we’ll explain the telltale signs of mice in your walls, why it’s a serious problem, and what steps you should take to eliminate the issue quickly and safely.

🐁 5 Signs You Have Mice in Your Walls

1. Scratching or Rustling SoundsThese noises usually happen at night when mice are most active. If you hear light tapping or scurrying behind your drywall, especially near baseboards or ceilings, it's a major red flag.

2. Mouse Droppings :Tiny, black, rice-sized droppings are a clear indicator. Check along walls, in kitchen cabinets, under sinks, and in the basement.

3. Chewed Materials :Mice have strong teeth and will gnaw through cardboard, wiring, insulation, and even plastic. Look for bite marks or shredded paper around storage areas.

4. Pet Behavior Changes :If your dog or cat suddenly becomes fixated on a particular wall or corner, they might be detecting movement or smell from inside.

5. Musty Odors or Urine Smell :Rodent urine has a strong ammonia-like odor. A foul smell coming from your walls or floors may indicate a hidden nest.

⚠ Why It’s Important to Act Fast

Mice aren’t just a nuisance—they pose serious risks:

• Health hazards from bacteria, droppings, and urine

• Fire danger from chewed electrical wiring

• Rapid reproduction, making small infestations big problems quickly

The longer you wait, the harder (and more expensive) it becomes to control the infestation.

🛁 What to Do if You Suspect Mice in Your Walls

1. Don’t Seal the Entry Right Away : Blocking holes before removing the mice can trap them inside, causing odor and wall damage. Always combine exclusion with trapping.

2. Avoid DIY Traps Alone : Snap traps and glue boards might help temporarily, but they won’t fix hidden nesting or entry points in walls and crawlspaces.
