Is Bayer for Rose Slugs Harmful for Ladybugs


njscubadiva added on May 28, 2015 | Answered

Can I used Bayer Advanced insecticide on my roses for the rose slugs if I will also be releasing ladybugs in the near future for the aphids? Or is there a more natural/organic way to get rid of the slugs??

The window of effectiveness on the Bayer Advanced insecticide is about eight weeks and, yes, it is harmful to ladybugs. How many rose slugs are you dealing with? If it's only a few, the recommendation is to pick them off by hand and dispose of them. However, if the problem is more large scale then the use of other means of control should be explored. The following article has organic strategies you can employ against rose slugs:
