Effect of Carbon Dioxide Fumigant on Controlling <i>Cimex lectularius</i> Linnaeus（Hemiptera: Cimicidae）

This study evaluated the effectiveness of carbon dioxide fumigant against bed bug adults and eggs. The test was conducted in a room populated by bed bugs. Bed bugs placed in test containers were exposed for two weeks in a test chamber with a carbon dioxide concentration of approximately 70% and a room temperature of approximately 25°C. Furniture inhabited by bed bugs was also treated in this chamber. The results demonstrated a 100% mortality rate for bed bugs after this treatment. Dead bed bugs that had fallen from the furniture were also found inside the chamber.
