Seasonal stink bug and invasive insect infestations ~~in residential areas~~

Stink bug species are increasingly entering residential buildings as they seek shelter for the winter months. In Poland, the American stink bug has been noted to enter homes due to dropping temperatures, appearing on walls, windowsills, and behind furniture. Dr. Lech Bucholz, a regional nature conservator in Kielce, noted that while these insects are herbivorous and generally not dangerous, they can cause discomfort through an unpleasant odor or by attempting to pierce skin if plant sap is unavailable. They can also contaminate food products like fruit. In Italy, observations regarding the Asian stink bug indicate that the search for indoor refuge can be triggered by decreasing daylight hours rather than just temperature. In Romania, Croatia, and Spain, reports indicate that as autumn approaches, insects utilize cracks in facades, window frames, and door gaps to find dry, protected spaces. Experts highlight the distinction regarding the invasive brown marmorated stink bug (Halyomorpha halys) from East Asia, which can cause significant damage to agricultural crops. In Bosnia and Herzegovina, the invasive brown marmorated stink bug has been spreading since its first record in the Mostar region in 2018. Professor Nedžad Karić from the University of Sarajevo notes that while the species was officially registered in the country in 2019, climate change—specifically warmer summers and milder winters—has facilitated their survival and spread. Recent reports from Germany and Bosnia and Herzegovina confirm that Halyomorpha halys is increasingly appearing in homes to seek winter hibernation. While harmless to humans and pets, they pose a significant threat to agriculture by damaging fruit, vegetable, and ornamental plants. To manage infestations, experts suggest sealing cracks with silicone and repairing window screens. Recommended deterrents include vinegar-based solutions, specialized insect repellents, or a homemade mixture of ground cinnamon Recent reports from Poland indicate that as autumn temperatures drop, the brown marmorated stink bug is appearing in homes, emitting an intense odor resembling rotting fruit when disturbed and ~~warm water sprayed around entry points.~~ potentially staining fabrics if crushed.
