African violets soaking up vodka.

 Vodka used to kill mealy bugs on African Violets:

One of my favorite African Violets

Vodka is a multi purpose liquid

When I saw a few white mealybugs on one of my African violets,
I ran for the rubbing alcohol to swab it and send it to mealybug heaven. 

No rubbing alcohol in the cabinet.

Chilled Polish vodka from my freezer made a fine substitute.

I swabbed the mealy bugs with the vodka and banished them.  I hope they don't come back for more!
