A fairly safe method is Bt but it takes a few days to work so they'll continue eating until they die.

Kristy, If I just had a penny for every worm I had squished, I would be a rich woman ! I don't know a quick fix, wish I did. Edna

Dang, last time I looked for BT I couldn't find any. Guess I will be sweet talking hubby into a trip to Killeen this weekend sometime. Until then I will squish away. John hates when I pull off leaves. He thinks it hurts the plants, lol.

The have drove me crazy this year and I sure know how you feel with the swiss cheese leaves. Those green worms do make a very satisfying crunch when you step on them, tho, don't they? :o)

lol........ been doing allot of crisp snapping since the 2 hail storms.

I hate crushing anything and my stomache turns. But THOSE s..... when I find them and right now they apeared again just knowing they are back by looking at the swiss cheese that is not in my fridge, which I love but not on the plants. I even take the whole leave off and squish them. Can not bring myself to touch them even with cloves lol.
Do I have a problem? :-)

They were having a ball on the most tender leaves of my
Shredded White and P&C...almost overnight on the P&C. I
could have cried! I mixed a tiny bit of week Sevin solution
and...no more problem. This was three weeks ago.
I removed the worst looking leaves and the plants are as
pretty as ever. I spray periodacally this way because it
only takes a few to do a LOT of damage.

I only have the powder form. Will that work if I sprinkle it in the pot or do you have to get it on the leaves? I can't touch them either. I snap of the leaves and squish the whole thing, lol. John took over because he couldn't bare to watch me take off the leaves. I cleaned up some while he was gone this morning, lol. I got a tiny sprinkle of rain for about 2 seconds earlier but there is another band coming. Come on rain! You cann dooo eeet, lol! If this one splits right before it gets here I am gonna throw a fit, lol.

I am so desperately waiting for rain that I am not really in a happy mood. But you sure made me laught Kristy.
Call me when and if we have to throw a fit....I come over...we go to that unfriendly dog hating neighbor of yours and throw the fit together lol

I am getting those dumb green worms as well. Every time I think I got them all, next day I find new holes on the leaves. I dusted my double white with Sevin. I've been so busy lately that I haven't noticed if it worked or not. That one plant looks horrible.

Lol, Lucy. I guess we are gonna have to commence the fit throwing. Still no rain. I got some BT and sticker spreader to spray with since I noticed some stupid bag worms in the tree today out back as well. I hate those things.
