HORTICULTURAL OIL READY TO SPRAY 32oz

A safe, non-chemical, organic solution for controlling soft-bodied insects and their eggs! Horticultural oil works by smothering the pests on contact, physically suffocating them. Because the Ready-to-Spray (RTS) hose-end applicator dilutes and mixes the oil for you, application is quick and easy.

• Best For:
  • Overwintering Pests (Dormant Use): Killing eggs and larvae of Aphids, Scale, Mites, and Pear Psylla on fruit trees, roses, and shrubs during the dormant season (late winter/early spring before bud break).
  • In-Season Use (Summer Oil): Controlling active infestations of Spider Mites, Whiteflies, and Scale on flowers, vegetables, and ornamentals.
  • Organic Gardeners: A reliable, environmentally friendly pest control choice.
• Key Actionable Steps:
  • How to Apply: Attach the bottle to your hose, turn the dial to "ON," and spray the entire plant—every square inch—until the surface is 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. The plant must be fully dormant (no green buds showing).
  • 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.
