Not every product is available to each of us. Insect vegetable dusts are very effective and often kill insects almost instantly. Most insecticide dusts, even organic dusts, are non discriminate killers. I think they have value in the garden and I use them this way... 7 PM dust the plants and 7 AM wash the dust off them. 12 hours is enough time to kill the unwanted insects. You are using it when more beneficial insects are NOT around.
