I have been fighting thrips on my daylilies all season. I have put out the granular stuff but some of the plants still have thrips living around the bottom. Grumbling Is there a good solution to eradicate them?

The only thing that works for me is to spray a systemic insecticide. Best done before daylily buds start to open for the summer but now is better than not at all. From my experience you really need to actually spray the buds and flowers to get rid of those thrips. But spray the daylily foliage also. Repeat in two weeks.

Rita, will the spray harm the bees or the humming birds??? I have a lot of damage on my daylilies this year, I think because our winter wasn't as cold so they didn't get killed off.

I don't know what spraying open flowers will do. I spray early in the year when there are buds only and then I spray about two weeks later to break the cycle. I spay in the evening when the bees are done if there are open flowers. By the next day, those flowers are gone. And the buds sprayed day before open but that doesn't seem to harm the bees. Never had a hummingbird interested in any daylily. So I would suggest not spraying in the morning or daytime when bees might be visiting.

I have always used Bonide (brand name) Systemic Insect Control.
