Scarlet lily beetle #878379

Asked July 23, 2024, 9:29 AM EDT

My asiatic and oriental lilies have been invaded by scarlet lily beetles this year. I've sprayed with Neem Oil, and I have been picking off the beetles and killing them in soapy water. I'm concerned that the beetles have killed the lilies. My question: Will my lilies return next year?

Expert Response

Whether your plants will die will depend on the extent of the damage.  If there is still a lot of green material, they should survive. If all the green is gone, maybe not. So wait and see what happens next year.  Here are two sites giving control options:
