Horticultural Oils are pesticides (typically mineral, cottonseed, neem) that control insects, mites (by suffocating them). Oils are good on some plant diseases as well like and some plant diseases (prevents the spread of spores on things like powdery mildew and rust). Horticultural Oils have no residual effects so the target pest must be present in order to be controlled and coverage must be thorough. When using outside, it should be used in the spring since summer heat may cause the leaves to sun burn after use (if foliage is in direct sun). Kills all stages of insects, including eggs.
Interestingly enough, Horticultural Oil is used as a dormant oil on fruit trees before the bud breaks in early spring and potentially again in the fall for certain pests. That's why we have this offered in a RTS bottle so that it can be attached to your hose for those hard to reach areas outside.
