What is the primary reason for dehydration-related death in cockroaches?

Answer

Exposure to environments significantly drier than their preferred habitat

Cockroaches are highly sensitive organisms that require consistent access to moisture to survive. When the ambient environment in a home is significantly drier than what they require, or when they are unable to locate water sources, they experience rapid desiccation. This state leads to weakness and sluggishness, eventually resulting in death. Environmental shifts, particularly seasonal changes that lower humidity, can drive roaches into drier areas of a home where they perish simply because the conditions cannot sustain their biological need for water.
