Worms killing my evergreen - help!

jennie_boyer(7)June 30, 2007

All,

I have a row of evergreens that are generally healthy. However, I have one tree that has somehow been overtaken by worms that are just now hatching. I didn't notice anything wrong with the tree until today, when it appeared to be brown and "moving". I've looked closely, and hundreds of little worms are hatching. I've attached a picture to help identify.

Questions - how do I get rid of these worms, how do I keep them from spreading, and will my tree recover?

TIA!

Jennie

Looks like Bagworms to me. On arborvitae or cedars? Treat them fast...it's already on the late side...or they will do a LOT of irreparable damage to your shrubbery!

Here's some links:

This article has a GREAT picture for you to compare as well as recommended insecticides. I think it's too late for the bacterial treatment:

Hi Robin,

Thanks for the quick follow up. They're on arborvitaes. I really didn't notice anything until yesterday, but will get on it today. Bag worms was my suspicion, but do they have one worm per bag?

Thanks!

One worm per bag and one bag per worm.
