How to get rid of mice in walls
Seal all entry points
The first task is to seal all the entry points to your house. This will ensure that new infestation does not take place as you go on removing the pest from the wall one by one. Mice have very strong teeth and jaws.
They can enlarge even a dime of a hole in the wall or roof of your house to wriggle through it. So every hole should be properly sealed. Even the entry points of service lines like electricity and water facilities connecting to your house should be properly sealed so that the mice cannot scratch at them and make way into your property.
You can set up one way exclusion funnels in the primary entry points. You can also place mouse traps at these points.
Whether you are placing mouse traps at the entry points or throughout strategic points of the house you should place suitable baits.
Peanut butter makes good bait for mice. Use a number of simple spring traps to trap several mice hiding in wall interiors. Keep them at strategic locations, preferably close to the walls, overnight and find them trapping mice in the morning.
Trap and relocate the mice to distant places until you can hear no more scratching, gnawing or clawing sound at night. Once you are sure that there are no more mice left in the house decontaminate the attic and other places and remove the rodent droppings.
