The answer to 'why is my stink bug recurring problem' is that stink bugs can be a persistent pest in many homes. Stink bugs often invade homes in the fall as they seek warm places to overwinter, and they can continue to be a nuisance throughout the winter and spring as they try to get back outside. Stink bugs may enter through cracks and crevices around windows, doors, and other entry points, and they can quickly multiply if left unchecked.
The key to managing a recurring stink bug problem is to take a multi-pronged approach. This includes sealing up entry points, using insecticides or traps to eliminate existing populations, and being vigilant about monitoring for new infestations. While some DIY treatments can be effective, more severe or persistent stink bug problems may require the expertise of a professional pest control technician.
