I spent one summer squishing red beetles when I saw them,and wiping off the grubs and their black mess. I always managed to miss one, who would strip a plant while I was at work. Last year the lilies got one spray, early on, and they were clear for the season, and my garden was full of bees. I also have lots of bees and butterflies this year. I wouldn't spray at all if the lilies were near to forming flower buds.
