Hornets in the house - what to do?
Interesting facts about Hornets
Many people have completely wrong ideas about hornets. They are not aggressive, caution is important only in the immediate nest area of three to four meters. As a rule, nests hardly disturb, because hornets are not interested in the food at the table of people. They eat insects.
The bite of a hornet is painful but harmless. A healthy person can handle over one hundred stitches. Only those who are allergic to the poison have something to fear. This also applies to stings of other wasps and bees.
No hornet's nest is inhabited for longer than six to seven months. The states emerge in May and perish in November. Sometimes hornets voluntarily move earlier if the nesting space is too small.
Unlike wasps, hornets rarely build free-hanging nests in attics. They prefer to build in columns or cavities. Although noxious noises are coming from the nest, the animals do not eat themselves into the entablature.
Building damage through the nests
A hornet's nest in the house is generally not a problem as the animals have the flight hole outside. So you do not fly through the house. The building is rarely damaged.
In exceptional cases, hornets nesting under the shingles reach the vapor barrier. From there you enter the attic. If this happens, the lock must be repaired.
Large nests on horizontal surfaces made of wood, hardboard or plasterboard may soften the material. This is indicated by a brownish, growing stain.
Behavior when there is a nest in the house
The best advice is simply not to do anything. Homeowners who discover a nest at the end of August or later have lived with it for four months. In three months at the latest, it is uninhabited. No more hornets will move in.
If the hornets fly around the house, they usually enter through an open window. Fly screens prevent this. If the hornet nest has a hole in the interior of the house, it is advisable to move it.
If people live in the house who are allergic to the poison, they also need to relocate. The same applies if a brown spot indicates that the building material is soaked through. There is a risk that it will break and a nest with exceptionally aggressive hornets will end up in the dwelling.
The Underground Conservation Authority of the community must approve the relocation. Of course, a specialist has to do the job. Hornets defend their nest and surely no one wants to expose themselves to the stings, even if you do not die from them. Specialists have the right equipment to prevent this from happening.
Organizations such as NABU or BUND help find a specialist. Sometimes communities or firefighters keep lists of farms ready.
Prevent Nesting in the House
There's not much homeowners can do to stop hornets from nesting. The best protection against a new nest is not to remove the old one. Whoever removes the nest, makes room for a new settlement. Sealing cracks also helps. Hornets, who want to settle in a roller shutter box, feel disturbed when the roller shutter is moved up and down several times a day. Sometimes the animals move on. Brush seals on the roller shutter box may also be of some use.
Since hornets are very useful, many homeowners go another one. You install near the house a hornet nest box. As soon as a young queen has settled the box, other queens avoid the closeness of the box and thus the adjacent area of the house.
