Stink bugs are invasive pests that gather in large numbers in houses and flats during autumn as they search for shelter. In gardens, they can damage many cultivated plants. Although they are not dangerous to human health, their presence can quickly become extremely irritating. Preventive measures and timely control can effectively limit their occurrence.
Stink bugs are most commonly seen from late summer into autumn, when they search for a suitable place to overwinter. At this time, they frequently enter houses, flats, garages, garden sheds and other buildings, where they may remain until spring.
In addition to being a nuisance indoors, they also damage fruit trees, vegetables and other cultivated plants. When threatened, they release the characteristic unpleasant odour that gives them their name.
Stink bugs do not enter indoor spaces in search of food. They are looking for a warm, safe place to overwinter. They most commonly enter houses and other buildings through open windows, doors, ventilation openings or cracks in the facade.
Their presence is most commonly encouraged by:
Once they find suitable shelter, large numbers of stink bugs may overwinter in the same location.
Stink bugs are not dangerous to people because they do not sting, bite or transmit disease. Nevertheless, they can cause considerable nuisance indoors, while their presence in gardens and orchards may also affect crop quality and yield.
The most common problems include:
Because they frequently gather on windows, walls and ceilings, many people find them particularly unwelcome inside the home.
Stink bugs occur both outdoors and indoors. During the warmer months, they are mainly found on plants. In autumn, they move into buildings to overwinter.
They are most commonly found:
Indoors, they prefer cracks, areas behind furniture, curtains and other quiet places where they can overwinter undisturbed.
Stink bugs are generally easy to notice because they often gather on exterior walls, window frames and balconies during autumn. As temperatures fall, they begin searching for suitable overwintering sites and may enter homes in large numbers.

If several stink bugs appear inside the home during autumn, inspect potential entry points and seal them appropriately.
The most successful way to control stink bugs is to prevent them from entering a building. If they are already present indoors, remove them in a way that does not cause them to release their unpleasant odour.
We recommend:
✔ fitting insect screens to windows and doors,
✔ sealing cracks around windows, doors and the facade,
✔ regularly inspecting attics, garages and other spaces,
✔ removing individual stink bugs with a vacuum cleaner or collection container,
✔ using dedicated insecticides when large numbers are present.
Do not crush or step on stink bugs, as they release a characteristic unpleasant odour when threatened. This odour may also attract other individuals.
The brown marmorated stink bug is an invasive species originating from East Asia that has spread widely across Slovenia in recent years. It can be recognised by its mottled brown body and characteristic pale bands on the antennae. It attacks many fruit, vegetable and ornamental plants and often enters houses and other buildings in large numbers during autumn.
The green shield bug is a native species most commonly found on trees, shrubs and other plants. Adults are characteristically green during summer but turn brownish in autumn, which helps them blend into fallen leaves.
No. Stink bugs do not sting or bite and are not known to transmit diseases. Their main disadvantages are their unpleasant odour and their tendency to gather indoors in large numbers.
In autumn, they search for a warm and safe place to overwinter. They most commonly enter through open windows, doors, ventilation openings or cracks in the facade.
Carefully remove individual stink bugs with a vacuum cleaner or catch them in a container and take them outside. If large numbers are present, use a dedicated insecticide for crawling and flying insects.
Fit insect screens, seal cracks around windows and doors, and regularly inspect potential entry points around the building.
The odour is a defensive mechanism used to deter predators. They release it mainly when they feel threatened or are crushed.
Stink bugs have become frequent visitors to Slovenian homes, particularly in autumn when they seek shelter from the cold. They are not dangerous to people, but they can be very unpleasant because of the characteristic odour they release when threatened.
