The answer to 'bee odor' is that a strong, lingering odor from bees is usually a sign of a bee infestation or nest nearby. This can happen if a bee hive or nest has been disturbed or damaged, causing the bees to release alarm pheromones that have a distinct, unpleasant smell. The odor is often described as sweet, musty, or like rotten bananas.
If you notice a persistent bee odor around your home, it's important to try to identify the source. Look for signs of a bee nest, hive, or swarming activity. Bees may have built a nest in your walls, attic, or other hidden areas. You'll want to address the issue promptly, as a bee infestation can pose safety risks and lead to further damage.
