If the rodent calls have started picking up this month, that's not a coincidence — it's the fall pattern showing up right on schedule.
Every September the combination of cooler nights and thinning outdoor forage pushes mice and rats to start scouting for warmer harborage. Homes are the obvious target. A house radiates a steady 65–75°F through its foundation and attic, and a rodent can detect that thermal signal from twenty feet away. Once one pregnant female slips through a quarter-inch gap around a utility line, the math gets ugly fast: five to ten litters a year, juveniles breeding at six weeks. One mouse in early October becomes fifteen to twenty by Thanksgiving.
Our new post covers where rodents actually get in, the earliest signs of an active infestation, and why a fall inspection is the highest-leverage call families make all year. Link in bio.
