Wasps are flying insects that live in colonies (wasp nests), usually in wall cracks, roofs, warehouses, attics, inside pipes, etc.
They are not necessarily aggressive insects, but they may attack and bite humans if they feel a threat to themselves or their nest.
With the sting of the wasp, poison is injected through its stinger, which as a result causes severe pain, swelling and redness of the area. Special attention is needed, since there are people allergic to wasp stings.
To control wasps, a universal spray with an approved insecticide is first applied, followed by destruction of the nest and then residual sprays.
