I potted them last year to see if it would help (and I mulched the pots with stone chippings) so fingers crossed.
Cutting off all the scapes for one season should, at least in theory, get rid of the midges from that particular garden unless someone close next door has them. But when I've suggested this to people in the past they were never too keen on the idea of not having daylily flowers for a whole season. Understandable, I guess. Interesting idea about the bags. If they are mesh bags then the female midges might still be able to deposit their eggs through it if it touches the buds anywhere, but then the bag should also catch the larvae as they try to get to the ground to overwinter.
Do please let us know what happens with the mulched ones in pots. I'd imagine that would work better if the pots had a fair bit of space between them. Are they far from the daylilies in the garden so that the flying adults from there aren't as likely to find them? I remember hearing about someone in the UK trying this but I'd have to look back through my correspondence to remind myself what the result was.
