How long does it take to freeze a cockroach to death?

Freezing a cockroach to death typically takes several hours, depending on the temperature. Cockroaches can survive in cold environments for a time, but exposure to freezing temperatures (around 0°F or -18°C) for an extended period, usually 4-8 hours, is generally lethal. However, they can enter a state of suspended animation and may survive brief exposure to cold, only succumbing after prolonged freezing.
