A bed bug sauna refers to a method of using heat to eliminate bed bugs by exposing them to temperatures high enough to kill them. Bed bugs, along with their eggs, cannot survive prolonged exposure to heat above a certain threshold (usually around 118°F to 122°F or 48°C to 50°C).
The concept of a "bed bug sauna" involves creating a controlled, sauna-like environment (in a room or a portable device) where temperatures are elevated to a level that kills the bed bugs, but not high enough to damage household items. Professional pest control services often use industrial heaters to turn a room into a bed bug sauna, or portable heat chambers can be used to treat smaller items like clothing, luggage, or furniture.
It's an eco-friendly alternative to chemical treatments, as heat can effectively kill all life stages of bed bugs without leaving any toxic residue.
