Hydrogen Peroxide Insecticide
Hydrogen peroxide, the same stuff you put on your cuts, is being touted as a natural insecticide. The household 3 percent version mixed one to one with water kills aphids and whiteflies on contact and may have a residual effect as well. When misted on houseplants in the same dilution, hydrogen peroxide seems to promote sprouting and deeper green leaves.
But be cautious. All plants may not react positively to hydrogen peroxide. You should always try a test spray on a few leaves and wait a day or so to see the reaction.
