# Seasonal stink bug and invasive insect infestations > Live situation record from CLSTR: https://clstr.news/situations/seasonal-stink-bug-infestations-in-residential-areas > Updated: 2026-10-09T21:45:00.000Z. Sources: 35. Developments: 7. 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. 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 potentially staining fabrics if crushed. ## Timeline ### 2026-10-09: Invasive insects enter Polish homes during autumn Invasive species like the Asian ladybird and the brown marmorated stink bug are entering Polish homes this autumn, causing odor and potential allergic reactions. 4 sources. https://clstr.news/cluster/invasive-insects-enter-polish-homes-during-autumn ### 2026-10-08: Asian stink bugs spreading across Bosnia and Herzegovina Invasive Asian stink bugs are spreading across Bosnia and Herzegovina due to climate change, posing risks to agriculture and prompting calls for pest deterrents like cinnamon-based solutions. 4 sources. https://clstr.news/cluster/asian-stink-bugs-spreading-across-bosnia-and-herzegovina ### 2026-10-06: Stink bugs invade homes in Germany and Bosnia and Herzegovina Invasive Brown Marmorated Stink Bugs are entering homes in Germany and Bosnia and Herzegovina seeking winter shelter, posing a threat to agriculture and causing odor issues for residents. 13 sources. https://clstr.news/cluster/stink-bugs-enter-german-homes-seeking-winter-shelter ### 2026-10-03: Stink bugs seek indoor shelter during autumn temperature drops Autumn temperature drops are driving stink bugs into homes.
