I thought 2021 was a masting year for many/most oak trees. This usually follows with a population increase in rodents, chipmunks, etc the following year.

Anyways, I have a somewhat older home, and used to have mice problems. Now about every few years in the summer I go around the foundation and do an old timers trick, which is to stuff steel wool around the rim joist of the house paying close attention to any small cracks etc. seems to have stopped the mice.
