@Weedwhacker Thanks, Sandy! There's one in each corner, and as of today the box is even more overwhelmed. They are exploding out over the sides now when I take the cover off. Something seems to be chewing on the leaves too - maybe earwigs or slugs
This is why I went with the cover, hoping to have fewer issues with bugs/animals. Do you think it's worth it to keep taking the cover on and off each day?
