I think you're supposed to put oil on it so that the thrips stick to the cup. Is that what you did Kentucky_Rose?

I have GOT to remember to do thisi tomorrow. Thanks for the reminder.

Husband put Kroger vegetable oil on them for me about a week ago. I was thinking about removing the cups cause I didn't think they were working and then I saw this! Previously, I had used W-D and maybe the vegetable oil works better? I still have lots of thrips in my blooms that I am spraying with Orthene. But the cups are working.

Got a few Thrips there?? I put them out during the Spring and they worked really well. The pink ones work too.

I coat our blue cups with generic canola oil...Works great! Our white/light roses look good now...

I finally remembered to put out my blue cups yesterday, but then didn't because we're expecting about 5 days of rain. It's probably to late, Chandos Beauty is already showing some color in between the bud sepals. Oh well, we'll see what happens. :)

I really have to try that!!
