Whiskey or an alcohol based liquid will kill soft-bodied bugs like
aphids almost on contact. I've used cheap vodka on some indoor houseplants
infested with those nasty little flies that nest in the soil. I've not used
it extensively so ymmv. My plants never show an adverse reaction to the
alcohol. I applied it with a perfume atomizer so that large drops never had
to sit on the stems and leaves. The alcohol would evaporate from the plants
quickly and leave the water (50 to 60 %) but would absorb into the critters.
I don't suppose the whiskey would do the roses' scent any good. <g> My
choice for aphids and such on roses is a systemic insecticide.
You're asking strangers if you should believe your wife? You're in trouble,
OK, lets give her the benefit of the doubt. Maybe you didn't hear her
correctly. Maybe she said it was for her cirrhosis.
