It is suitable for indoor, outdoor, and greenhouse use and can be applied up to the day of harvest. Ideal for light to moderate pest pressure on a variety of edible and ornamental plants.
Best use guidance: spray thoroughly on all plant parts, including undersides of leaves. Caution: direct application to beneficial insects should be avoided when possible, and avoid spraying in temperatures above 90°F to minimize leaf scorching.

Buying Guide
Key considerations when choosing an organic insect spray for vegetables:
- Pest spectrum: Prioritize products that explicitly list the pests they target in vegetable crops (aphids, caterpillars, whiteflies, mites, etc.).
- Edible-use labeling: Confirm that the product is labeled for use on edibles and whether it allows treatment up to the day of harvest.
- Application type: Decide between ready-to-use sprays and concentrates based on your garden size and application preference.
- Impact on beneficials: Some sprays may affect beneficial insects; look for formulations designed to minimize harm to pollinators and natural enemies.
- Ease of use: Consider spray coverage requirements (leaf undersides, stems) and whether the product requires mixing, shaking, or multiple applications.
- Fall and seasonal use: For disease control, check whether the product also has fungicidal properties and how that aligns with your garden’s seasonal needs.
- Safety and residue: Review safety cautions, temperatures for application, and any residue considerations for harvest timing.
