- Organic insect sprays can relieve gardeners' concerns over the possibility of toxic pest control substances ending up in their soil, fruits, or vegetables. These home-grown solutions can also cost less than chemical preparations.
- Many common kitchen substances, mixed with water and sometimes soap, can kill pests. Cayenne pepper, for instance, kills mites, while canola oil smothers mites and other insects. A mix of dormant oil and lime sulfur keeps pests away from fruit trees.
- Water-based organic pest control substances require only a standard household spray bottle as an applicator. Oil-based sprays, however, require a professional-grade pump sprayer. Some treatments work the first time, while others may need repeated applications.
- Gardeners should wear gloves or other protective garments when applying organic sprays just as they would when working with chemicals. Organic preparations can kill "good" insects alongside pests, so users should target problem sites only when spraying.
