It is exceedingly simple to remove paper wasps.  In the cool of the evening
or very early in the morning, take a stout paper bag and surround the nest
from below.  Drop the nest into the bag and quickly twist the bag shut.
Apply a large twister, as used to close plastic bags, to the twisted neck.
Carefully and slowly squeeze out the air.  With all the air out grind the
bag under your feet.  The nest and wasps will be crushed.

I often eliminate small nests by donning gloves and crushing them in my
hands while the wasps are cool and logey.  Wasps are not very quick when
they are cool.

I try not to eliminate bald-faced hornets, which also build paper nests,
for though they may occasionally trouble bees, they consume huge quantities
of flies.

If one observes the insects that make paper nests on weathered wood, one
may hear them chewing off the raw material for their nests.
