The answer to 'why is my stink bug infestation' is that stink bugs are a common household pest that often invade homes in the fall as they seek warm places to overwinter. Stink bugs are attracted to homes by the warmth and can enter through cracks and crevices, often congregating in large numbers. Symptoms of a stink bug infestation include seeing the bugs themselves, finding their egg clusters, and noticing a distinct unpleasant odor when the bugs are disturbed.
To solve a stink bug problem, you can try DIY methods like sealing entry points, using insecticidal sprays, and vacuuming up any visible bugs. However, for severe infestations or recurring problems, it's best to call in a professional pest control technician. They can properly identify the species, assess the extent of the infestation, and use targeted treatments to eliminate the stink bugs and prevent future invasions.
