HELP!!!

I have been battling mealy bugs for 2 1/2 years. I have tried dish detergent, alcohol, neem oil, volk oil, Bayer 3 in 1, ladybugs ... but they just won't die!!!!! I have lost many beautiful plants and I am afraid to get any more.

I live in zone 10b, with a patio container garden. My patio door is open most of the year, so of course the wind has carried these demons into the condo and onto my house plants.

Is there any way to get rid of these things once and for all? Or do I slowly watch all my plants die, wait 6 months, then start over???

Any help is greatly apppreciated!!!!!
