Hornets
Hornets are the largest of the eusocial wasps. In most cases, their workers reach body lengths of around 20 millimetres. The animals normally have a striking colouring, with a basic brown to blackish-brown colouring and vibrant yellow patterning on the thorax and the tergites of the abdomen.
Behaviour:
These persistent insects occur in swarms in the summer. They are attracted by sweet food in particular. In the autumn, the males die; the young females hibernate in protected areas such as attics, etc.
Damage/illnesses:
The sting causes a reddened swelling. Occasionally, the insects can transmit pathogens with the sting. In extreme cases, allergic reactions to the venom can be fatal.
Control:
Spray individual insects with Neocid EXPERT Insect Spray. If this does not eliminate the nuisance, the nest has to be found and combated with Neocid EXPERT Forte Wasp Spray.
Prophylaxis:
Place a glass of sugared water at a distance.
Install fly screens on the windows.
Do not leave sugary food lying around.
