A Strange, Musty Odor

Trust your nose—it might be the first to know.

A significant bed bug infestation can produce a distinct, musty-sweet odor. Exterminators often compare it to the smell of coriander, almonds, or overripe raspberries, which is caused by the bugs' alarm pheromones when disturbed. If your room develops a persistent, unexplainable scent, it’s time to investigate further.
