How to Get Rid of Rodents in Walls

To get rodents out of your walls, find their entry points, set traps where the wall void meets an open room or the attic, remove any that die inside, then seal every gap with chew-proof material. Trapping inside a sealed wall rarely works on its own — you have to intercept rodents where they enter and exit.

Scratching inside a wall is unsettling, but it's a solvable problem. Here's the right way to do it.

Why rodents get into walls

Wall voids are warm, dark, and protected — ideal rodent highways between the attic and the lower floors. Rodents usually reach them from above (via the attic and roofline) or through gaps around pipes and wiring that pass through the wall. Because rats and mice climb so well, a vertical wall cavity is no obstacle.

Signs rodents are in your walls

• Scratching or scurrying inside the wall, usually after dark
• Squeaking or faint gnawing sounds
• Droppings near baseboards, outlets, or where walls meet floors
• Gnaw holes in drywall near the floor
• Grease smudges along baseboards
• A musky odor, or — worst case — a dead-rodent smell

How to get rid of rodents in walls

1. Locate entry points

Rodents in the wall got there from somewhere. Inspect the attic above the affected wall and the exterior for gaps at the roofline, vents, and utility penetrations. Trace activity to where the wall void opens into the attic or a room.

2. Set traps at exit points

Don't tear open the wall. Instead, place snap traps where rodents leave the wall to find food — near gnaw holes, along baseboards, and in the attic above. Bait with peanut butter and position traps flush against the wall. Our guide to catching a rat covers placement in detail.

3. Encourage them out (avoid poison in walls)

Skip poison bait for in-wall rodents. A poisoned rodent often dies inside the wall, creating a strong odor for weeks and attracting flies. Trapping at exit points lets you remove them cleanly.

4. Seal every gap

Once activity stops, close the entry points with galvanized hardware cloth and sheet metal. Seal gaps around pipes and wiring with rodent-proof material. This is the step that makes the fix permanent.

5. Clean and deodorize

Disinfect droppings and grease trails (wear gloves and a respirator; mist, don't dry sweep). Removing scent trails helps prevent new rodents from following the same path.

What if a rodent dies in the wall?

If you smell a dead rodent, the odor typically fades over 1–2 weeks as it dries out. For faster relief, a technician can often locate and remove it. This is one of many reasons trapping at exit points beats poison.

Frequently Asked Questions

How do I get a rodent out of my wall without opening it?

Set baited snap traps at the points where the rodent exits the wall — gnaw holes, baseboards, and the attic above. Most rodents leave the wall regularly to find food and can be caught without cutting drywall.

Why shouldn't I use poison for rats in walls?

Poisoned rodents frequently die inside the wall cavity, causing a lasting odor and attracting flies. Trapping lets you remove them cleanly and confirm the problem is solved.

How long will a dead rat smell in the wall last?

Typically 1–2 weeks as it dries out, though it varies with size and humidity. A professional can often locate and remove it to speed things up.

Will rodents in the walls go away on their own?

No. Walls offer shelter and safe travel routes. They'll stay and breed until they're trapped out and the entry points are sealed.
