Wasps
Wasps are NOT bees.
They may look like bees, they sting like bees, they even sound like bees, but they do not produce honey and their nests are not made of the same substance.
Wasps could create a nest out of mud or wood but bees only make their nests made of honey.
The type of nest produced by wasps can depend on the species and location.
Many social wasps produce paper pulp nests on trees, in attics, holes in the ground or other such sheltered areas with access to the outdoors.
Wasps are very aggressive from August to October. During these months, their food shifts from insects to food and garbage. During these months, wasp could be found in food and garbage. Unintentional contact happens which could lead to a wasp attack.
