Which method of infested mattresses can effectively kill bed bugs?

• A. Vacuuming
• B. Sun-drying
• C. Freezing
• D. Steam cleaning

Answer: (D)

Bed bugs hide in mattress seams, folds, and tufts, so reaching them with enough heat is key. Steam cleaning delivers hot, penetrating steam that reaches into those crevices and kills bed bugs at all life stages on contact, including eggs. Vacuuming can remove some bugs but often misses eggs and hidden insects, sun-drying and freezing aren’t reliably effective because they don’t ensure uniform heat or long enough exposure to all hiding spots. With careful technique, steam cleaning provides the necessary heat and penetration to inactivate bed bugs inside the mattress.
