I use this in the "off" season when lady bugs (larve) are in hibernation Get some lump alum - it is used in pickling. make a super-saturated solution by dissolving it in hot water. 2 tablespoons to 1 pint of water. Cool - add 2 tablespoon Dawn dish detergent and 2 tablespoons Listerine. spray on the aphids. say goodbye. -- Andie Paysinger & the PENDRAGON Basenjis,Teafer,Cheesy,Singer & Player asenji@earthlink.net So.
