Which odor may indicate a heavy bed bug infestation?

• A. Fresh odor
• B. No odor
• C. Musty odor
• D. Sweet odor

Answer: (C)

Bed bugs release pheromones from their scent glands, and when many of them are present, these odors combine into a noticeable musty smell. That musty odor is a telltale sign that the infestation is substantial, since it requires a population large enough to produce a strong collective scent. A fresh odor wouldn’t typically be associated with bed bugs, and no odor would suggest either no infestation or a very small population. While some descriptions mention a sweet nuance, the musty odor is the best indicator of a heavy infestation because it reflects the presence of many bugs emitting odor signals.
