Q.Bag Worm Elimination
I have an arbivitae that is loaded with bagworms (seemed to happen literally overnight!). They are starting to spread to neighboring shrubs. I got an organic spray (Neem triple strength) from our nursery, but so far haven’t gotten good results. What else can I do? Picking them off by hand will take a LONG time – there’s a lot of them!
