In any event, these and other techniques for exterminating
a nest—including spraying—should be attempted
only at night, when all the wasps are inside the nest and
relatively inactive. All paper wasps are vision fliers, and
cannot navigate in the dark. Your chances of getting all
the insects in a colony are much greater, and the odds of
your getting stung much less, when you do the job at night.

Finally, learn to recognize the warning signals most wasps
give off when they feel you're too close. A
Polistes wasp on the nest will lift its wings,
raise its front legs and rear up on its back legs. A hornet
or yellow jacket (or, more rarely, a Polistes )
may warn you away from the nest by flying straight at you
fast. Normally, wasps fly in a somewhat slow, meandering
fashion as they forage; if a wasp comes toward you in this
manner, it means no harm and will likely fly past you. If
it gets too close, don't swat at it: A slow movement or
gentle wave will send it on its way. Running from a wasp is
pretty much futile, since a paper wasp's normal cruising
speed is about 13 mph, and its pursuit speed is
considerably faster. Likewise, don't panic if a wasp
accidentally lands on you; it'll probably leave on its own
momentarily, or you can make a slight shrugging movement to
encourage it into flight.
That's all easier said than done, of course. Cool
objectivity is fine when you're looking at a wasp from a
scientific, arm's-length point of view—but when
you're looking at a wasp on your arm. . . well
now. Me, I still go into head-to-toe adrenaline overdrive
whenever a wasp or bee buzzes too close. My stomach still
leaps to my throat, my heart still pounds like a punching
bag. Out of sheer, stubborn pride, I usually
—usually—manage to stand my ground. But
mentally I run like a rabbit.
There's something about man's fear of wasps that goes
deeper than reason. Maybe it's just the natural order of
things. Maybe, in addition to all the other roles the wasp
plays in nature, there's another: to keep us humans
humble.
