growing Madonna lilies and also all Fritillarias as I've found that no

Regals, seem to stand up to them better giving you time to kill the
beetles/larvae before the whole plant is consumed.

You are very unlucky. I've reduced my lily population this year (one
of those occasional re-design things) but still have about 100 of
various types growing. So far this year I've found 2 red devils. The
cat ate one; I split the other asunder. A daily check does the trick.
If numbers suddenly increase then I resort to Provado Ultimate Bug
Killer for a single spray. That restores the balance and I can carry
on with the fingernail job.

I have never experienced any plant destroyed by lily beetle.
