Ugh! Lily foliage was awful last year. First time I’d noticed lily beetles in my garden, but it was late to minimize the damage. I generally avoid sprays when I can, but they decimated the lily foliage last year. I’ve noticed that the plants are significantly smaller this year. Less damage this year as I knew what to look for, but they keep coming. It’s constant vigilance with both the beetles and the larvae. Any success stories out there?

I wanted to revive this post to see what you ended up doing. I just found Lily leaf beetles for the first time, and talking to some of my demoralized friends, I’m tempted to pull up all my lilies while I still can (I’m not particularly attached to them, though they’re my major source of summer bloom for a period).
Did you have luck with neem oil? Is it a losing battle? I just can’t handle picking and squishing everyday.

Don’t pull your lilies! In April I start hand-picking the little red devils and squishing them. I know, it’s late, but I started then and seem to have got them all. No new holes in a couple of weeks.
And yes, I would try the spray regimens in those links up top — I will if I see any more visitations. How can we not grow lilies? As you say, summer wouldn’t be the same…I think it’s worth the effort. (I say this having a few big clumps, not 1000 square feet of them or anything, fyi.)
Keep us posted what happens.May 20, 2010 at 10:47 pm #29457
I was very sad about losing all my lilies to beetles; I even bought Sevin, but freaked out when I read the label. So when I moved to NY, where they weren’t supposed to be having beetles yet but would soon, I did some research and found that lilium ‘Black Beauty’ was supposed to be somewhat beetle-resistant. So I planted some. I have since squashed a fair few beetles; I have them planted close to a path so I can examine them, and I squash the beetles and their eggs. I cannot say that this cultivar is more resistant; I doubt it, actually, because I think it’s my vigilance rather than their inherent resistance that has helped; but I have had a few lily blooms, and only a few holes in the leaves. The problem is that lilies, being tall, are not graceful planted handy for squashing.May 21, 2010 at 12:01 am #29461
You can tell by my member name how I feel about Lilies – a favorite! So I have been screaming about lily beetles for 2 years now from New Canaan CT and no one was listening. But slowly garden friends are beginning to notice the damage. let’s hope they are like the gypsy moth caterpillars that surge in population and then disappear for a decade. Until that dream comes true, I am vigilant about picking the red beetles – especially the mating couples! (Found two after dinner on my lily beetle hunt). And the disgusting larvae, I squish with rubber garden gloves – it’s nasty but I love my lilies so it must be done. I wont use sprays. Oh, I have a dog named Lily too!May 25, 2010 at 5:01 am #29467
The beetles wiped out my tiger lilies, and got nearly all of my orientals last year. This year I’ve been picking the nasty little things off by hand and it seems to be working.July 20, 2010 at 6:05 pm #29545
Lily Beetles will be my undoing. I have so many oriental and asiatic lillies in my gardens and they are devastated! Summer oil didn’t work, and hand-picking is difficult since I am a weekend resident and can’t seem to stay ahead of them. I was in my Berkshire garden for the whole week last week and each day I squashed many many beetles, and the next day there were always more! Will they overwinter in zone 5, or will this be a one-time shot, does anyone know? I am heartbroken over my (formerly)beatiful lillies. With the foliage nearly gone, they will surely not reappear next year. Woe is me!July 27, 2010 at 12:37 am #29549
The adults will overwinter in the soil and plant debris. The second post on this thread has some good links. It sounds like neem oil might work for you, if you can’t do the hand-picking.
