Wasps are common visitors to gardens, terraces and balconies, particularly during the summer months. Their stings are painful, and nests near the home may pose a risk to people, especially those with allergies. Timely action and suitable solutions can effectively limit their presence.
Wasps are most active from late spring until early autumn, when they search for food and build nests. They are most commonly encountered near gardens, terraces, balconies, restaurants and other areas where sweet drinks, fruit or food residues are available.
If wasps build a nest near the home, their presence can quickly become dangerous. It is therefore important to identify the nest early and take action safely.
Wasps search for food, water and suitable nesting sites. In spring, queens begin building new nests, which grow rapidly throughout the summer.
Their presence is most commonly encouraged by:
Wasps most often build nests beneath roof eaves, in attics, garden sheds, wall cavities or other sheltered spaces.
Wasps are an important part of the natural environment, but they can become a serious nuisance when they are close to people. Their stings pose the greatest risk, particularly when they defend a nest or feel threatened.
A wasp sting may cause:
Sensitive individuals may experience a more serious allergic reaction requiring immediate medical attention. Stings to the face, mouth or throat and multiple stings are particularly dangerous.
In addition to the health risk, large numbers of wasps may make it difficult to use gardens, balconies, terraces and other outdoor areas.
Wasps build nests in sheltered locations where they are protected from the weather and food is readily available nearby.
They are most commonly found:
Individual wasps are also frequently seen on terraces and balconies, at picnics, in orchards and near outdoor waste bins.
Individual wasps are common during summer. A larger number repeatedly appearing in the same location often indicates that a nest is nearby. Pay particular attention if wasps continuously follow the same flight path or disappear into a specific opening.
The most common signs of wasp activity are:
If you notice increased wasp activity in one location, do not approach the nest or attempt to remove it without suitable protection.
If wasps appear only occasionally, their presence can be reduced by removing food sources and restricting access to potential nesting sites.
We recommend:
✔ clearing away food residues and sweet drinks,
✔ emptying waste containers regularly,
✔ removing overripe fruit,
✔ sealing openings that provide access to buildings,
✔ using insecticides specifically intended for wasps.
If you discover a nest near the home, proceed with caution. Do not remove it during the day, when wasps are most active, and do not attempt to damage it mechanically. Professional pest control is recommended for larger or difficult-to-reach nests.
The common wasp is one of the most widespread species in Slovenia. It is attracted by sweet drinks, fruit and food residues and is therefore frequently encountered at picnics, on terraces and in gardens. It builds nests in the ground, in attics, beneath eaves or in other sheltered places.
The German wasp closely resembles the common wasp but often forms larger colonies. It commonly nests in wall cavities, beneath roofs or in the ground. It may become highly defensive when threatened.
Wasps are attracted by food, sweet drinks, ripe fruit, waste and flowering plants. If they appear repeatedly in the same location, a nest may also be nearby.
Observe the direction in which the wasps fly. If several individuals repeatedly enter the same opening or location, a nest is very likely to be there.
Small and easily accessible nests may be treated with a dedicated product when suitable protective measures are taken. Professional assistance is recommended for larger nests or nests in difficult-to-reach locations.
Wasp activity peaks during summer, particularly from July to September. They are most active on warm, sunny days.
Cover food and drinks outdoors, avoid waving your arms, do not walk barefoot on grass and deal with nests near the home promptly.
Many people consider wasps to be among the more dangerous and aggressive animals they may encounter and certainly do not want them nearby. A wasp sting can cause very unpleasant skin reactions and, for people with allergies, may even be life-threatening.
Wasp and hornet nests close to the home can present a serious risk, particularly when disturbed. Learn how to recognise them, when removal is necessary and how to approach treatment as safely as possible.
