The answer to 'why is my stink bug invasion' is that stink bugs are common household pests that can enter homes in search of warmth and food, especially in the fall. Stink bugs are attracted to light and heat, and they may find their way inside through cracks and crevices in your home's exterior. They can quickly multiply and become a nuisance, releasing their signature foul odor when disturbed.
To address a stink bug problem, you can start by sealing up entry points around your home, using caulk or weather stripping. Vacuuming up any stink bugs you see can help, but be careful not to crush them, as this will release their unpleasant smell. For more severe infestations, you may need to consider using insecticides or calling a professional pest control expert.
