pests White bugs and powder under my habanero leaves

[ThePizzaMonster]

So today I found this white bugs under the leaves of my habanero plants. They were surrounded by kind of a white powder and they left after I started looking around. I did manage to take a couple of (very crappy) pictures before. What are they? Should I be worried? This is the first time I see these particular bugs and I check under the leaves pretty much everyday.

Maybe mealybugs? hard to tell from the picture but either way, they need to die. They're not good.

I was reading I could use soapy water on them but the problem is there are none at the moment. How can I prevent them from coming back?

Whitefly.

I had those on my Scorpion Moruga.  Basically used a combination of physical crushing, Venus fly trap and soapy water to eradicate them.  I'm with Edmick on this one, they need to be liberated from life.

So far I've been just crushing any bugs I find. What combination of soap and water do you use? I've read to use dish soap, castille soap, soap without degreasers, there seems to be no consensus. Also, do you rinse it off after a while?

I've read to use dish soap, castille soap, soap without degreasers, there seems to be no consensus.

I see this again & again:
 
Now pour 2 tablespoons of dish wash liquid.
+ dishwashing liquid,
What is insecticidal soap. Is it just fancy way of saying dish soap.

Dishwashing liquid is not soap....> Homemade Insecticidal Soap Recipe:
 
Pure Soap: Use a pure liquid soap, such as Castile, or all-natural soap. The active ingredient in insecticidal soap comes from the fatty acids in animal fat or vegetable oil, so it’s important to use the real thing. Don’t use detergents (which aren’t actually soaps)

Fire works well too...hairspray and a lighter.

Castille soap is probably the best option of the bunch. Yes, you wash it off after 15 minutes.

These are not mealybugs.  They are 100% whitefly.  And they're tough.  Wherever there's one, there's at least 1000 more near by.
 
Also, to the OP... These insects are difficult to treat, because they have a lifecycle that renders certain treatments ineffective, at certain times.  You need about 2 weeks of continuous treatment to get ride of them, to ensure that you kill the larva that were just emerging while you were busy killing their adult parents...
