A safe, non-chemical, organic solution for controlling soft-bodied insects and their eggs by smothering them on contact. Because the oil physically suffocates the pests, they cannot develop resistance, making it an essential tool for all gardeners.

• Best For:
  • Overwintering Pests (Dormant Use): Killing eggs and larvae of Aphids, Scale, Mites, and Psylla on fruit trees, roses, and shrubs (applied in late winter/early spring).
  • In-Season Use (Summer Oil): Controlling active infestations of Spider Mites, Whiteflies, and Scale on flowers, vegetables, and ornamentals.
• Key Actionable Steps:
  • How to Apply: Thoroughly spray the entire plant—every square inch—until dripping wet. The oil must physically cover the pest to work.
  • Timing (Dormant): Apply on a clear day when temperatures are above freezing and expected to remain so for 24 hours.
  • Timing (Summer): Do not apply if temperatures are above 90°F or if the plant is drought-stressed, as this can cause leaf burn.
  • Pro Tip: Always spray when plants are not in bloom to protect beneficial pollinators.
