Green worms eating the roses...ughhhh. rose slug?

Can someone tell me if they are rose slugs, or something else ? What should I do or did wrong?

I'm going to hose them viciously first thing in the morning. May visit the garden store too. But your thoughts/knowledge are wanted too badly.

All my roses have them. The new shoots are being eaten. The underside of leaves have tiny white things in oval shape, eggs that haven't hatched yet? And a few green worms too, around the holes eaten off. Not a whole lot yet but enough to get me worrying. The roses haven't been that happy looking since coming home with me.

I am terribly fearing to lose my baby roses. These are the circumstances I figure related. : 1) many ants are bothering my roses since I planted them a week ago. I read that ants are protectors of the worm by keeping their predators away. 2) rose leaves have been flopping down or curling up a bit for a few days already. 3) when planting I used compost+mushroom+top soil. So I may have over fertilized and caused the problem?

I'm at the greater Vancouver area of BC Canada, zone 6a maybe? I'm new to gardening that's why. :( thanks!

Ants are busy around somehow, lots of tiny white oval things - as photo says.

Ok, caterpillar worms are probably cutworms- a skeletonizer that moves in en masse from moths.
Ants are known to 'farm' aphids for their dew. 2 seperate problems. Aphids tend to resist poisons, tho some have luck with neem oil used carefully

yes you are right. Confirmed they are two different bugs here. Got the spray from store and for they crawling creatures too. A good hose seemed to help. Sprinkled some coffee ground as neighbour suggested. Hope will get it under control.
Thx so much kittriana!

Hi DreamyKind-
I don't know about the worms, but I do know about Hardiness zones. You are likely in zone 8b, like me across the border. Some of the greater Vancouver area is actually 9a, generally near the water. Now don't get too excited about growing 8b plants- Tallahassee, Florida is also 8b, and we all know it is NOT the same. Hardiness Zones only describe how cold it gets in winter. A new map of "Heat Zones" has come out, some plants are also ranked for that. You are maybe Heat Zone 2, like me, which is 1-7 days above 86F, Tallahassee is Heat Zone 9, which means 121-150 days above 86F ! The last few summers have been exceptional, with hot weather here like California-if this is the new normal some things may be OK here that I previously could not grow because they want more heat in summer.
Here is a link to a zone map you might want to look at:

Oh and another thing I thought of while doing the dishes-
Hardiness Zones are from the USDA, a US government agency, but have been adopted in many other countries (using Celsius of course).
Heat Zones are from the AHS (American Horticultural Society) a private group, they are new so less known.
You may have also heard of "Sunset Zones". These are from Sunset Magazine, and are a good attempt to incorporate both coldness and summer heat into one zone system. You are likely Sunset Zone 4, like me. Just for comparison, the mountains are Sunset Zone 1, Seattle is Sunset Zone 5, Portland is Sunset Zone 6, San Francisco is 17. You might want to take a look at the Sunset Western Garden Book, where this is all explained, and many many garden plants and shrubs and trees are listed by zone. It's not perfect of course, some things I can grow are not listed for my area, but it is an excellent starting point for newish gardeners. This Grevillea is an example of one that I grow, not listed as hardy here (of course if we have a "hundred year freeze" this winter I may be singing a different tune).
