How Mice Enter Homes
Mice enter homes through cracks and holes found in walls, floors and foundations. Homeowners commonly do not recognize mouse holes until other signs of infestation appear. Due to their body shape, mice are capable of fitting through holes much smaller than appear likely.
Mice may also enter the home through gaps in windows or ceilings, as well as through sewer lines. If drainage pipes are not properly sealed, mice may enter homes through sink or bathtub drains. They are also known to find their way inside via entry holes around plumbing and oven gas lines.
As a result of dropping temperatures, infestations tend to begin in fall. After a colony enters a structure and finds it to be safe and warm, they rarely venture outside again. Mice proliferate quickly and populations may exceed 200 specimens within a matter of months.
In order to prevent mice from entering the home, all cracks, openings and holes should be sealed with metal or cement. All doors and windows must close properly. Store foods in glass or metal containers with tight lids, and be certain to dispose of all food waste as soon as possible. Contact a pest control professional for help and additional solutions.
