The answer to 'stink bug nests' is that stink bugs do not build traditional nests like some other insects. Instead, stink bugs tend to aggregate in large groups, often in sheltered areas like cracks and crevices in walls, under tree bark, or in attics and eaves of homes. These aggregations are not true nests, but rather overwintering sites where stink bugs gather to survive the winter months.
Stink bug infestations can be a nuisance for homeowners, as these pests can enter homes in large numbers seeking shelter. The best way to address a stink bug problem is to seal up potential entry points around the home and remove any existing aggregations. For severe or persistent infestations, it's often best to call in a professional pest control technician who can properly identify the issue and implement effective treatments.
