Bayer 3-in-1 will get rid of some of those bugs. It will also kill the predator wasps, ladybugs, and any mantids and create an environment where the bad bugs return sooner than their predators. For those aphids, rose slugs, and mites, a simply spray of water is nearly as effective as a kill'em-all insecticide. These are the easier of the pests to knock off of rose bushes. The rain should be part of your pest control, and not contributing to the infestation. I believe all of the ones you listed prefer hot & dry conditions.

That is actually a Hairstreak butterfly caterpillar. They are beautiful butterflies, and if you can find a more expendable hibiscus, put it on that. Good Luck!

i gave up on roses a long time ago .. 100 hybrid T's .. because of the chemical regimen needed for perfect plants ... like 4 to 5 sprayings over the course of the season ... of a multitude of products ... but jean is correct.. if you just a have a bush or two.. its a LITTLE COSMETIC DAMAGE.. and not worth the effort ... be amazed by the show.. rather than horrified with it ken
