Some may move toward structures around that time, but mice often begin seeking protected shelter before the first freeze.
Mice do not want to be outside in the cold. But it’s not necessarily the first freeze that forces them inside. In fact, they start trying to find ways indoors long before that. Mice respond to changing weather, food availability, and shelter needs as the fall goes on.
Garages and cabins become more and more useful as temperatures continue to drop. If the structure has gaps around doors, foundations, vents, utilities, or siding, mice may move inside before anyone sees frost. A first freeze can make existing activity more noticeable, but if rodents can find a way inside through a crack in the foundation or a worn garage seal, they’re happy to do that before the first frost ever arrives.
Seasonal cabins tend to have more of a problem with rodents. A large part of this is simply the fact that they sit unused for longer periods of time. If rodents go inside, it could be months before anyone notices. While there, rodents have free rein over garages which often have things like stored food and seed that they can eat or cardboard and fabric which they can shred to make nests.
If you don’t want rodents to take over your cabin or garage, one thing you can do is check exterior openings in the fall. Seal up any gaps you find around garage seals, doors or windows, utility lines, or cracks in the foundation. Mice are tiny and can slip into spaces about the size of a dime, so it’s easy to overlook a potential entrance point.
While there, secure food and reduce unnecessary clutter. If rodents do manage to make it inside, it’s best to make sure they’re not more comfortable than necessary while there.
