The European Hornet is a species of wasp belonging to the hornet genus, Vespa. It's the only true hornet that's native to Europe, and it tends to be regarded as a pest wherever it's present. The negative connotation associated with these insects has resulted in population drops, they've even been given the endangered status in some European countries. They're voracious predators, subduing large prey items that include dragonflies, beetles, spiders and smaller wasps. Like bees, they'll spend most the day collecting resources for the larvae back at the nest.
Hornets can sting when they feel threatened.
These insects contribute to maintaining a healthy, balanced ecosystem being a natural form of pest control.
The thorax is brown, and the abdomen stripey black and yellow- they look like wasps but about 2x the size. Tip: the invasive Asian hornet is browner than our native species. A European hornet is obviously yellow, whereas an Asian hornet will be distinctively dark with one yellow abdominal band.
Wasps (mainly European) provide services that if absent, might cause pest populations to rise. If you can't tolerate the hornets, it's suggested to arrange professional removal and extermination because they can become aggressive when threatened.
It's not recommended to treat gardens with hornets.
