How do I get rid of the grubs on my Vibernum without hurting my cats…are there any sprays that are non toxic? I hear that pyrethrum is fatal to cats of which I have 3.
A long as you don’t actually spray the cats with Pyrethrin, it won’t kill them. Keep them inside while your spraying and until the shrubs dry and all will be well. You also use insecticidal soap but your shouldn’t spray the cats with that either. Read and follow the directions on the label.
