Mice in the Walls: Removal in El Paso
Scratching inside the walls at night usually means mice using the wall space as a hallway. A technician finds where they get in and out and closes it off.
Mice in Walls Removal in El Paso: the short version
Mice in the walls is one of the most common rodent calls. You hear scratching or scurrying after dark, usually in a kitchen wall, behind a bathroom or near the water heater. The mice are using the space between studs to travel and nest, and they come out where pipes, wires and cabinets leave gaps.
You cannot trap them inside a closed wall. The work happens at the openings: under sinks, behind the dishwasher and stove, at the water heater, in the garage, and around outlets and vents. Find those, trap there, and seal them.
What a thorough job includes
A walls job is mostly detective work and sealing.
- Listening for when and where the sounds happen, which narrows down the wall section
- Checking cabinet bases, plumbing holes and appliance gaps on both sides of that wall
- Looking at the outside wall for the gap the mice use to get in, often near pipes, vents or the slab
- Traps at every inside opening, checked on a schedule
- Sealing pipe and wire holes with steel wool or copper mesh plus sealant, and covering larger gaps with metal
- A plan for a mouse that dies inside the wall, if one does
Mice in Walls Removal step by step
- Map the soundsNote when you hear them and where. Mice are most active at night.
- Check the openingsThe technician opens cabinets, pulls out appliances where possible and looks at every gap where plumbing or wiring enters the wall.
- Find the outside doorThe outside of that wall, the garage and the roof are checked for the route in.
- Trap at the exitsSnap traps go where mice leave the wall, in cabinets and behind appliances.
- SealInside gaps and the outside entry get closed with chew-proof material. The CDC lists steel wool for small holes and metal, cement or hardware cloth for larger ones.
- Listen againSounds should fade within days to a couple of weeks. If they do not, the technician looks for a second route.
Why it is harder in El Paso
Many El Paso homes are stucco over frame or block, and the gaps that matter are where utilities pass through. Water lines to a rooftop cooler, gas lines to the water heater, and the conduit for outdoor air conditioning or lighting all leave openings. Stucco also cracks where it meets the slab.
Desert neighborhoods add pressure. Homes near open land, arroyos or the river valley see mice from outside year round, with more after cold snaps and summer storms. Sealing has to be thorough because there will always be more mice nearby.
A mouse that dies inside a wall in summer can smell strongly, so technicians tend to avoid poison in occupied walls. Ask about that when you call.
What it costs and how long it takes
Most mice-in-walls jobs are small to medium. National cost guides put typical rodent jobs between about $176 and $886, and sealing between $175 and $600, depending on the number of gaps. A kitchen wall with one or two pipe openings and a single outside gap can be done in a visit plus follow-up. A house with several noisy walls usually means more entry points and more time. Our cost guide has the published ranges.
What you can do today
Empty and wipe out the cabinet under the sink nearest the noise, using the CDC cleanup method if there are droppings. Move food into sealed containers. Set two or three snap traps inside that cabinet, flush against the back wall near the pipe opening, baited with a small dab of peanut butter. Check them every morning. Do not put poison in the cabinet or the wall. Then call to have the outside of the house checked, since the gap mice use to reach the wall is usually somewhere you cannot see from inside. Our mice in the walls article has more detail.
Before the technician arrives
Clear out the cabinets under the kitchen and bathroom sinks and make space to pull out the stove and fridge. Note when and where you hear the noise.
Mice in Walls Removal: common questions
Why do I hear mice only at night?
Mice are mostly active after dark. Daytime noise is more often a sign of a larger or heavier population, or of rats.
Can mice chew through drywall?
Yes, they can gnaw through drywall and many soft materials. That is why sealing uses metal, cement or mesh.
Will they cut holes in my walls?
Usually not. Most wall jobs are handled at existing openings like cabinets and pipe gaps.
Is it mice or rats in my walls?
Light, quick scratching points to mice. Heavier thumps and gnawing point to rats. Our noises at night article helps tell them apart.
What if a mouse dies in the wall?
The smell usually fades in a week or two. If it is strong, a technician can try to find and remove it. See dead rodent removal.
Can I seal the gap under my sink myself?
Yes. Pack it tightly with steel wool or copper mesh and lock it in with caulk or foam, as the CDC describes. The outside entry point still needs to be found.
