yea the author was also organic and NW Pacific coast. skip to the pest section, might be some info. You should be able to find lady bugs and praying mantis somewhere, I worked at a nursery upstate and we sold them, seasonal but we carried them.
I tried to find them for years here (deep south) with no luck, moved from my garden last year, walk out the other day and find about a dozen praying mantis on my truck. Couldnt believe it. Theyre terratorital so they stick around and hunt where they were born.
BTW the hop leaves look good. I think should they withstand this assault.
