Holes in Hostas

Asked September 2, 2016, 2:00 PM EDT

I have over 300 hostas. In the summer some if them had holes. I started to treat them for slugs in June. They continued to get worse over the summer and now all are c bcc ewed up. I see small bugs that look like a small ant. Could they be chewing the leaves? I am wondering if there is anything I can do this fall and or early spring to solve this problem. Any help would be greatly appreciated. Thank you, Judi

Without a photo, all I can do is guess. If the small bugs are ants, no, they are not doing the damage. However, once the leaves have tears, the decaying matter will attract other insects.

If you've seen (and still see) slugs, then they are most likely the problem. Read here about slugs:

If you don't think slugs are the problem, try this diagnostic site:

Or write back and include photos.
