The answer to 'stink bug swarms' is that stink bugs are a common household pest that can gather in large numbers, especially in the fall as they seek warm places to overwinter. Stink bug infestations are caused by the insects seeking shelter and food, and they can quickly become a nuisance as they release their distinctive foul odor when disturbed. Homeowners may notice large numbers of the shield-shaped brown bugs congregating on the exterior of their homes or flying around inside.
Stink bugs do not pose any serious health risks, but their presence can be unpleasant. Effective solutions include sealing cracks and entry points, using insecticidal sprays, and removing any food sources or harborage areas. For severe infestations or hard-to-reach areas, it's best to call in a professional pest control technician who can safely and effectively eliminate the stink bugs.
