Why Do Stink Bugs Stink?

Stink bugs, known for their foul odor when threatened, are a global pest affecting over 100 plant species, including key crops like apples and soybeans. Originating from Asia, the brown marmorated stink bug is the most common type. Their odor, a mix of cilantro and skunk, is due to aldehydes in their scent glands, which also have antifungal properties. These bugs have few natural predators, allowing them to spread widely. They seek shelter in homes during colder months, releasing pheromones to attract others. While harmless to humans, they can be a nuisance, and it's best to prevent their entry by sealing windows and doors.
