German Wasp (Vespula germanica)

The German wasp has bold black and yellow stripes and shows aggression when its nest is threatened. Originally from Europe, North Africa, and Asia's temperate zones, these wasps live in various parts of the world, including North America and New Zealand. 

German wasps are fond of beer, even sipping from the glasses of unsuspecting people outdoors. 

They build nests made of chewed wood pulp in human structures. While people consider these insects a nuisance, they control pest populations by eating spiders and small invertebrates. They also eat nectar and fruit.

Moreover, a German wasp’s sting can trigger allergic reactions in some people. However, they only attack when threatened. Unlike bees, they can sting multiple times, though they are not naturally dangerous.
