Last year and early this season, I had problems with leaf miners in my chard. This year I stopped them with vigorous harvesting and Spinosad. But from mid-summer on, they've been plagued with something that makes tiny little holes. Leaf miners made paths and patches. These are too small for slugs or snails. I'm very familiar with those pests. The harvesting/Spinosad approach doesn't seem to be working.
Any advice?

Possibly flea beetles.
Huh. Yeah, that's the kind of damage they cause. But we always have lots of flea beetles in the early part of the season, attacking small plants, and they're quite visible. I haven't see any. BUT, the chard is along the edge of the garden, and they hide in grass.... I'm going to spray the grass, as I did in the spring.
Thanks for the suggestion.
Any other thoughts from the rest of you??
