Cockroaches
Do cockroaches die in winter?
Outdoor American cockroach and oriental cockroaches slow when it is truly cold. German cockroach live in heated structures year-round. Winter does not reset a kitchen. If anything, they concentrate on the warm appliances. Keep baiting and sealing.
Season is not a treatment
A first freeze that kills a few outdoor wanderers does nothing to the refrigerator motor colony. Monitors in January still catch nymphs. That is your census.
