The answer to 'bed bug odor' is that a strong, sweet, musty odor can be a sign of a bed bug infestation. Bed bugs release pheromones that produce this distinctive odor, which some people describe as similar to coriander, almonds, or spoiled raspberries. The odor becomes more noticeable as the bed bug population grows.
If you notice this unusual smell in your home, it's important to inspect your bedding, furniture, and other potential hiding spots for other signs of bed bugs, such as small blood stains, shed skins, or the bugs themselves. Catching an infestation early is key, as bed bugs can quickly multiply and become very difficult to eliminate.
