Can an exterminator get rid of mice in the walls?
Yes. An exterminator gets mice out of the walls by finding where they get in, removing the mice with traps and tamper-resistant bait, and sealing those entry points so new mice can't follow. Mice in walls almost always come from outside through small gaps around pipes, vents, the foundation and the roofline, so sealing is the step that keeps them gone. Silver Bullet mouse service is $250 for a single-family home and $375 for a two-family home, with a 30-day warranty.
Signs the mice are in your walls
🔊
Noises at night
Light scratching, scurrying or squeaking inside walls and ceilings, mostly after dark when the house is quiet.
💩
Droppings at the baseboards
Small dark droppings shaped like grains of rice along baseboards, under sinks and behind the stove and fridge.
🕳️
Small holes and gnaw marks
Holes about the size of a dime at the bottom of walls, around pipes and behind appliances, with chew marks around the edges.
👃
Musty or urine smell
A stale, musty smell in cabinets or closets that share a wall with where the mice are nesting.
🐈
Pets watching the wall
Cats and dogs staring at, pawing at or sniffing one spot on a wall over and over.
🔌
Chewed wires or insulation
Mice chew wiring and pull insulation for nests, which is a fire risk if it goes on for long.
Why you shouldn't put poison inside the walls
Poison placed inside walls usually works, but the mouse dies where you can't reach it. A dead mouse in a wall can smell for weeks and draw flies. Poison also does nothing about how the mice got in, so new ones move in after.
We use traps and tamper-resistant bait stations placed where mice travel but kids and pets can't reach, and we seal the gaps they're using. If you already have a dead mouse smell, see what to do about a dead mouse smell.
How we get mice out of the walls
1
Find the way in
We inspect outside and inside for gaps around pipes, vents, the foundation, garage doors and the roofline.
2
Remove the mice
Traps and tamper-resistant bait stations set along the routes mice use inside the walls and along the house.
3
Seal the gaps
Entry points closed with materials mice can't chew through, so new mice can't get back into the walls.
4
Follow up
Your mouse service has a 30-day warranty. If mice come back in that time, call us.

Mice in walls questions
Can an exterminator get rid of mice in the walls?
Yes. We find where the mice get in, remove them with traps and tamper-resistant bait, and seal the entry points so new mice can't follow. Mouse service is $250 for a single-family home and $375 for a two-family home, with a 30-day warranty.
How do I know if I have mice in my walls?
Common signs are scratching or scurrying in the walls at night, rice-sized droppings along baseboards and under sinks, small chewed holes near pipes, a musty smell and pets staring at one spot on a wall.
Will mice in the walls go away on their own?
Usually not. If they have warmth, food and a way in, they stay and keep breeding. They need to be removed and the gaps sealed.
Should I put poison in the walls?
We don't recommend it. Mice that eat poison often die inside the wall, where the smell can last for weeks. Traps and tamper-resistant bait stations placed by a professional, plus sealing, work better.
How small a hole can a mouse fit through?
Mice can squeeze through a gap about the size of a dime, which is why sealing small gaps around pipes, vents and the foundation matters.
