A little ammonia applied to the puncture will speedily relieve the
pain, and so will the juice of an onion obtained by cutting an onion
in half and rubbing the cut part over the part affected. It is
necessary, however, to be very careful in any attempt upon a wasp, for
its sting, like that of the bee, causes much pain and frequently
induces considerable swelling. In case of being stung, get the
blue-bag from the laundry, and rub it well into the wound as soon as
possible. Later in the season, it is customary to hang vessels of
beer, or water and sugar, in the fruit-trees, to entice them to drown
themselves. A wasp in a window may be killed almost instantaneously by
the application of a little sweet oil on the tip of a feather.
