I have two shrubs that are infested with bagworms. Another shrub in the yard appears to be dying but i don't see any bags on the shrub. I have three other shrubs that at this point are unaffected. I applied Sevin and it rained two hours later. What else can I use to prevent the destruction of my shrubs in light of expected rain over the next three days. Thank you
Bagworms can be managed in a couple of ways. If the shrubs or trees are small enough, or only have a few bagworms, pick them off by hand and destroy them.
If you wish to spray with an insecticide, that is only effective in late spring.
Please see UK's publication on Bagworms, Entfact 440, that describes in detail how to manage them in a landscape.

I hope this helps!
