Winter doesn't shrink the rodent population
Winter doesn't reduce their numbers — it simply drives them indoors.
The common belief that rodent problems subside in winter is based on observations outdoors: there are few tracks in the snow and little visible movement. Indoors, the picture is exactly the opposite. The rodents that arrived with the cold have not gone anywhere — they have simply stopped venturing outside.
In winter, the population is concentrated in warm places with access to food and water: basements, utility floors, warehouses, equipment rooms, and livestock buildings. Where temperatures remain stable, breeding continues year-round.
In practical terms, a winter pause in control is not a saving but a problem deferred. By spring, the population will be noticeably larger than it was in autumn.
A minimum winter program is straightforward. Bait stations remain in place and are checked regularly, bait is replenished as it is consumed, and points with consistently high uptake require particular attention — a nest or entry route is usually nearby.
