Pretty sure I have an infestation of root aphids.
FoxFarm Bush Doctor Force of Nature Insecticide RTU is designed for use on houseplants for foliar or soil surface insects such as aphids, fungus gnats, and spider mites. We would not recommend this product for root aphids since it is not used as a drench or labeled for new plantings. Please let us what kind of plants you are treating and whether they are for home use or commercial so that we can better assist you.
