 Eventually they go away or they're done. But can you take care of them? Yes. The wet soaking the soil sometimes works. Otherwise, seven, eight, probably spinosad, spraying like that will knock them down as well. We'll try the heavy sprinkler route. That's an easy one. Give that a shot first. Your plants are going to love you for it and see what happens. And if it doesn't, then you can come back and do a little spraying.
