Qoute.... 1. Make a homemade fly trap. Pour wine or juice into an
open-mouth
container, and add a drop or two of liquid soap. Stir, then wait for
them to get trapped in the liquid. Change out the wine or juice as
needed........end quote.

And just in case anyone wonders why the dish soap in the recipe?.....it
breaks the "surface tension" of the water and as they land on the
surface of the juice expecting to float ....they can't and they sink
and drown.It works perfectly....and yes it works great for wasps as
well.....andy j.
