Mosquito Treatment:

So you don't like those pesky mosquitoes. Here's a tip that was given
at a recent gardening forum. Put some water in a white dinner plate
and add a couple drops of Lemon Fresh Joy dish detergent. Set the dish
on your porch, patio, picnic table, park bench, or other outdoor area.

Not sure what attracts them, the lemon smell, the white plate colour,
or what, BUT ... mosquitoes flock to it, and drop dead shortly after
drinking the Lemon Fresh Joy/water mixture, and usually within about
10 feet of the plate.

TRY IT---it works just super! It may seem trivial, but it may also help
to control mosquitoes around your home, (especially in areas where the
West Nile virus is reaching epidemic proportions in mosquitoes, birds,
and humans).

Pass this on to anyone who likes sitting out in the evening, or when
they're having a cook out.
