I was so busy looking down and keeping an eye on spider mites and other critters that I hadn't noticed the number of bagworms that have invaded my evergreens..... These are very tall mature trees - what can I do to save them ......

Thanks for any help .... Valarie

We moved into a place where all the arborvitae (20'+ tall), as well as all the deck structures, were COVERED with them.

I just spent as much time as possible picking off as many as I could reach & squashing them on a regular basis. It took 2 years of diligence, but with no chemicals my evergreens - & everything else - are 100% bagworm free.

I've heard that sprayings/dustings with BT will also deter them, but once they've built their little "bags" they cease feeding, & they have to feed to absorb the BT.

You climbed clear up in the tree to pick them..... I was hoping that would be my last resort.... but it sounds like I better get out the ladder and start climbing ...... I guess I know what I'll be doing this weekend..... Thanks

Yes, unfortunately. And I HATE heights - lol!!1

Obviously I couldn't reach all of them, but the work did save the day. One tree in particularly that we thought we'd lose because of the defoliation bounced back in rare form & now you wouldn't even guess that it had ever been touched by pests.

If they are in my reach, I pick them and then burn them. : /

I've even had some luck using the hose nozzle turned to full-force stream to knock the bags apart when they were too high for me to reach. It doesn't get all of them, and for a severe infestation it might not get enough of them, but it's worked for me.
