Don't know about the cut worms, but coffee grounds are very good for your compost.
Unfortunately no one on my house drinks coffee.

Same - no clue on cutworms or top-dressing with coffee grounds, but we add a lot of coffee grounds to our compost pile, and the various earthworms are certainly not hurt. Maybe the caffeine makes them perky enough to escape the birds!
— Ok, my bad, cutworms are actually moth larvae; in other words, caterpillars. I did several searches (cutworms coffee grounds site:edu), and I found nothing about using coffee grounds (or diatomaceous earth or crushed egg-shells, etc.) All references were to eliminating plant debris and other hiding places, hand-picking, protecting stems with aluminum foil etc., and various nuclear options if things get completely out of control.
My own guess is that it wouldn’t hurt, but dunno if it helps. Since caterpillars are soft-bodied, it might be an interesting experiment to save your egg shells, roughly crush them, and spread them around.

Seriously, nothing like a good detective hunt, especially in IPM (Integrated Pest Management.)
