Bonide Bon-Neem II Fungicide - 32oz - Ready-to-Use Trigger Spray

Neem Plus Pyrethrin for Fast Knockdown and Lasting Control

Neem oil alone works gradually, disrupting insect development over time rather than delivering an immediate knockdown. Bonide Bon-Neem II pairs neem with pyrethrin, a fast-acting contact insecticide, so an existing pest population gets an immediate hit while neem's antifeedant and growth-regulating effects work on what pyrethrin misses.

This 32oz ready-to-use trigger spray requires no mixing and controls a broad range of insects including stink bugs, boxelder bugs, and fungus gnats, along with mites and common fungal diseases, across vegetables, fruit, nuts, herbs, spices, roses, flowers, shrubs, houseplants, and turfgrass.
