Hand-picking or spraying the lilies with a pyrethroid are the only control options. This article describes more about the beetles and managing them:https://www.canr.msu.edu/news/lily_leaf_beetle_watch_out_for_this_garden_pest
I would also encourage you to report the location of the lily leaf beetles (called scarlet lily beetles on MISIN) to help MSU researchers understand how these insects are spreading. This beetle is very active in the Detroit area, and we have fewer reports from surrounding Counties.
I hope this helps. Thanks for using our service.
