I had to laugh, I've had the cut worms here march down a row of little onion seedlings & have a great meal. Ate over 100 before I found them all. Must be tougher in Alaska or just hungrier

I think the "white millers" are the mature stage, dragon flies love them but never get them all.
Aphids a problem some years too, in warmer wet years they've been real bad.
I may add some mint, I heard that helps for aphids.
It just goes crazy here & get into everything over a few years, but smells nice. May keep it in pots & place in around the edges.
