Most traditional insecticides “poison” pests, typically as a neurotoxin. Many of these insecticides have a long residual effect, meaning that they will continue to kill insects for days or weeks. One unfortunate side effect is that desirable, beneficial garden insects may also be poisoned within this time frame. Summit Year-Round® horticultural spray oils work differently than standard insecticides.Targeted for
Year-Round® Horticultural Spray Oil targets “soft-bodied” insect pests. Instead of poisoning, the oil suffocates or “smothers” these insects and their eggs. The oil spray blocks an insect’s air holes (spiracles), causing it to die from asphyxiation. These oils kill a wide variety of insect pests such as aphids, scale, adelgids, whiteflies, spider mites, mealybugs, thrips, and more. As horticultural oils must cover the target pest to be effective, there is no long term residual effect.
