I have heard a lot of good things about using parasitic wasps. It said on wikipedia that the neem oil spray would kill the larva but you got to do it every seven days, that stuff is good for mites too and is non toxic for bees. I think I will use it every week next year to help with the mite population too.
I will be watching this thread so I can do some preventive maintenance, I was reading about the rosetta disease and learned that a lot of mites over winter in canes so I think I will be removing canes and doing more cleaning this year. I can buy seeds for the birds, no problem. Just in case any lily beatles lay eggs in my canes.
