Green caterpillar with red head eating rose leaves

What is this bug? It's an inch-long caterpillar with a distinct red head, chewing holes in my rose leaves. I found a great picture online, but no really useful info. I'm in DC, and these things are destroying the foliage on my roses, as well as some of my vegetable plants. Most importantly, how do I get rid of them?

You got yourself a rose slug there. (Also known as sawfly larvae). Alas it will not make a beautiful butterfly.

I have these! I just pick them off by hand every morning.

Yes, they're sawfly larvae. They completely destroyed (as in stripped every leaf) of a willow we planted. You can pick them off (not an option when you've got tens of thousands of course) or use an insecticide.

Pretty sure that's the Hungry, Hungry Caterpillar. (Okay, actually just coming to say yes, sawfly larvae).

Neem oil or insecticidal soap. Reapply after rain or as needed. Unfortunately the bacterial solutions will not work.
