I just used the Bonide Brand Systemic Insect Control. Thats exactly what it said on the white plastic container. I feel that you need a systemic to really clear up the problem. I bought this at a local nursery and you can also buy these things on line.

Hey, I know some of you spray for thrips so how about it? Share some knowledge here LOL!

Not sure what the bottle labels says since I am at work, but it is Ortho (made by The Scotts Company) and I believe it is Malathion Plus Insect Spray Concentrate. I mix it with water in the sprayer and liberally spray the plants. And I do mean "Liberally"! I thought the instructions said something about "wet". So far, none of my daylilies have died because of it, and I haven't noticed any more damage other than the first blooms that either dropped off or were splotchy.

Here is a link to the product label that is probably on the back of most products containing Malathion. This is the Bonide label which is probably on the bottle that Rita mentioned.

I spray early in the season, just as the dormants are up and growing with Avid. This controls aphids, leaf miners and thrips. A month later, I spray with Merit 75WSP. It controls the same insects, but is better at controlling spider-mites. That's it for the season, unless something pops up!
