 o
invisible caterpillars?

Posted by oldryder (My Page) on

I have what looks like caterpillar damage on some of my apple trees and my rhubarb plants have been decimated.

I have found the occasional caterpillar on my trees. They're not the green stripe eastern tent caterpillars I've had issues with before as I've learned to kill them in their nests.

I also sprayed BT twice so far this year on the apple trees but I still see leaf damage which looks like caterpillars despite the fact that with very few exceptions I've seen no caterpillars.

So ...
if caterpillars where do I look for them?

if not, then what.

any reason not to keep spraying with BT? some other pesticide recommended?

thx in advance for help.

Well, the only thing is, if they're not caterpillars but some other insect, Bt won't do it. I'd use something else just to be sure.
