Mealy Bugs (aka Woolly Aphids)
A couple of natural suggestions I had seen and used on my indoor houseplants, using a Q-tip:
Rubbing alcohol and soap. Mix straight rubbing alcohol (no water), and 1/2 a teaspoon of dish soap. The dish soap, again, works to break down the waxy coating, and the rubbing alcohol will dehydrate the mealy bugs, killing them.
Other soaps, diluted 1 tablespoon to 1 pint water. Besides dish soap, you could mix water with the Murphy's Oil Soap or Dr. Bronner's organic peppermint soap. Not only will this kill mealy bugs, but it will keep other pests away, because parasitic insects don't like the strong scent of peppermint.
