Stink bugs are attracted to the foul chemicals and pheromones that other stink bugs give off. The brown marmorated stink bug, in particular, gives off an odor that helps attract stink bugs to adequate shelters during the winter.
While there are several different types of stink bugs, the brown marmorated stink bug has become one of the most problematic. These bugs can easily spread disease to crops and infest many residential homes. Based on their pheromones, they can often lead more stink bugs to unwanted destinations fairly quickly.
Stink bugs are also attracted to light, which is why they often swarm around lamp posts and porches. When swarming, they typically make a lot of noise, which can be a nuisance to homeowners. The best way to control stink bugs outside is by turning off outdoor lights or moving lamps away from home entry points.
There are products on the market to help target stink bugs by mimicking their scent. Customers can buy a natural spray that emulates the bugs' smell and leads stink bugs to an area in which they can be easily trapped. Although stink bugs give off an unpleasant smell and are difficult to be around, they do not damage properties or have the capability of biting or stinging humans or other animals.
