Watching them work…
How many do I need?
Use 5 persimilis? per 10 ft2 (m2) or 20 persimilis? per infested leaf, weekly, as needed. Apply predators to each infested plant. These come in a bottle with corn grit (so they can live until you get them). Depending on the severity of the infestation, simply sprinkle the same amount on each plant and watch closely. This is a numbers game – you want to overwhelm the spider mites with predators!
