In cold climates they never were a problem. Family just waited for a freezing weather, and spent a night at a neighbor house.

For a bonus, leave a hot kettle at the house center, so cockroaches gather near it and can be easier to remove once frozen dead in the morning.

You can destroy your indoor plumbing this way.

Indoor what? My grandmother didn't have none. I used to help her bring fresh water every morning from a nearby well.
