The answer to 'why do I have stink bug' is that stink bugs are a common household pest that can invade homes, especially in the fall as they seek warm places to overwinter. Stink bugs get their name from the unpleasant odor they release when disturbed or crushed. They feed on a variety of plants and crops, and can be a nuisance for homeowners.
Stink bugs typically enter homes through cracks and crevices around windows, doors, and other entry points. They're attracted to light and warmth, so they often congregate near windows and around lights inside the home. Stink bug infestations can be difficult to control, as they reproduce quickly and can be challenging to eliminate once established.
