The answer to 'signs of stink bug' is that the most common signs of stink bugs in your home include seeing the bugs themselves, finding their brown or green shield-shaped bodies, noticing a foul odor, and seeing damage to plants or crops. Stink bugs are nuisance pests that can infest homes and gardens, feeding on a variety of plants and releasing a pungent odor when disturbed.
Some key signs to watch for are the bugs themselves, which are about 1/2 inch long with a shield-shaped body, as well as small puncture marks on leaves, fruits, and vegetables from their feeding. You may also notice a distinct stink bug odor, especially if you accidentally crush or disturb them. Stink bugs tend to gather in large numbers, so seeing more than a few is a clear sign of an infestation.
