Hi! Can anyone identify what these bugs are (or more importantly if they are harmful to my rose plant)? The past few years, this rose plants health seems to be deteriorating, and there always seems to be holes in the leaves. I have hosed aphids off the plant several times this season. I also fed the plant compost and miracle grow plant food at the beginning of the season.

The little black guys are some type of wasp. They are harmless to your Rose.

The white stuff looks like mealybugs. The wasps are probably drawn there by the mealybugs.

Hi KraftyNutkin,

I am not sure what is eating holes in your rose bush's leafs, but I am having the same problem with some of my plants. It has been suggested I used Neem Oil or BT, so I am looking into that now. Just ordered a garden sprayer and plan to look for the BT and Neem Oil at Walmart and Lowes tomorrow. If I cannot find what I want at either place, I can order it through Amazon or Home Depot to pick up at the store. You might want to look into Neem Oil and BT. I know there are also sprays specifically made for roses.

Gosh you are brave growing roses! I love roses and would love to have tons of the, but I always heard they are very difficult to care for. Good luck and let us know what you find out!
