What is it and how do I stop it???

Hi Riverman123,

Welcome to ATP and welcome to the Agastache and Salvias forum.

I don't know, but hopefully, @FBTS will chime in and know the problem.

Is it off the edges? Pinholes? Whole leaves gone? Do you have a picture?

its mostly in the center of the leaves. eating everything in between the veins. sorry, no pic at the moment.

Pests are so regional that out-of-our-area pests are difficult to diagnose. Go out at night with a flashlight and look for the culprits. From you description it could be many, many different pest species.

Kermit gave some good advice. One pest that came to mind is earwigs and they do most of their damage (feeding) at night and hide during the day.

Danita,

That's the same thing I thought of too.

Thanks for chiming in Kermit!
