- Aphids
- Organic
- Vegetable gardens
- Soft bodied insects
A go-to organic-approved spray for aphids and other soft-bodied pests on vegetables and ornamentals; contact-only, so coverage and repeat timing matter.
Pros
- Low-toxicity, OMRI-listed option safe to use on food crops per label
- Kills soft-bodied pests on contact with no lasting soil residue
- Concentrate is economical, making several gallons of spray
Cons
- Only works on direct contact — no residual protection, so repeat sprays are needed
- Can cause leaf burn (phytotoxicity) on sensitive plants, in heat, or on drought-stressed foliage — spot-test first
- Ineffective against beetles, caterpillars, and other hard-bodied or chewing pests; can harm beneficial soft-bodied insects if sprayed directly
