I use this. It's natural and works for me here in the midwest. Active ingredient is pyrethrin and neem.
Pyrethrin
Bug bombs commonly contain pyrethrin, a natural component of chrysanthemums. While pyrethrin is approved for use in organic crops against insects, you should exercise care when using it. It can
irritate the skin and respiratory track and is
toxic to bees.
Neem Oil
Neem oil and products containing limonoids like azadirachtin disrupt the hormonal system of most common insects but is
relatively safe for mammals except at high doses. If you need to use it before harvest, you might want to think about rinsing off the buds afterward. Growers don’t normally use neem preventatively, but highly vulnerable plants may benefit from neem oil systemically; water an affected plant with a very dilute solution to combat infestations.
