Question: [header] How to get rid of the whitefly [title] Vacuum the flies. [step] Use a small hand vacuum, or hold the furniture-cleaning nozzle of a standard vacuum cleaner.

Lice and hornets can be pregnant bees or even cobwetters. (C) [substeps] Once you've vacuumed up all of the insects, you can dismantle the insect and wash it off. Plant diseases like freeze burn-gas are very likely to have mites, fungus, or other biological problems with this insect.

Question: [header] How to make oreos with dutch cocoa powder [title] Cream the butter and sugar together in a standard mixer. [step] Beat on medium speed until the mixture turns a light color. [substeps] Alternatively, you can whisk the mixture by hand. <sep> (A) The butter and sugar still combine and the two ingredients may not turn out the way you desire. The cream powder sugar has to remain even in order to make it smooth and effective. (B) [title] Add the egg and vanilla after turning the mixer to a low speed. [step] Blend for a few minutes until the ingredients are well combined. (C) Keep the mixer in a stand mixer with a whisk attachment. As it's moving, the mixer will shake the liquid that runs out of the hand mixer into the bowl, so it will avoid creating air pockets under the mixture. (D) There are two methods of beating butter, and if you're unable to whip the ingredients, you can manually process the ingredients in a food processor. As you sift the flour, you'll whip the cornstarch until the two ingredients are evenly blended together.
