Blend with a splash of water. Pour into your bucket and add water.
Ferment for a day or so.
Strain and spray on pest-sensitive crops. No need to spray willy-nilly. Just use it where it's really needed, or you risk killing beneficials.
It's best to spray in the morning or evening because the hot sun will break down the molecules, decreasing its efficacy.
