How often are you appllying the Sevin. I use it and spray about every two weeks. It sure got rid of them for me.

Google "lily Beetle" (with the quotes so it searches as a phrase).

Here's one link, but there are many more.

Here is a link that might be useful: lily beetle

Great links. Thank you. Been doing some research myself. Unfortunately, just got hit with them this year. Rats.

I encountered them for the first time as well this year. I don't recall having them last year. From what I've read they started in Massachusetts.

My "fancy" lilies are covered and all chewed up. I called the local garden centre and they recommended 2 products

1. Wilson's Bug X
2. Target Neem This is an organic product.

My husband scraped the larvae off with a pocket knife. It didn't kill them but at least they are off the plants and I will pick up one of the above products tomorrow.

This is the first year we have grown lilies other than day lilies and the "Tiger Lilies" that seem to grow wild around here.
