Insecticidal Soap: A Targeted Tool, Not a “Safer” Magic Bullet

Soap is a chemical (alkali + fat). Insecticidal soap dissolves insects’ waxy coating, killing soft-bodied pests like aphids. It’s tested not to harm plant cells—unlike herbicidal soap. Home brews risk herbicidal effects. Use it because it works on young insects, not because it’s “safer.” It won’t kill hard-shelled beetles.
