Seriously, this is pretty disturbing. First, they're attacking one of my mints, which they have never touched before - in fact I've never seen any aphids on any of my 3 mint cultivars.
Insult to injury - diatomaceous earth is not killing them! Until I can get my hands on some neem oil or garlic spray this weekend, I have had to resort to killing them by hand. Nothing else is coming close to even controlling them. Ick.
Normally they wouldn't be a problem until later in the year anyway, but this spring has thrown everything off. If it were warmer out I could get some aphid lions, but temps are back closer to normal now and they wouldn't survive the nights yet.
The d. earth is the same brand I always have used in early spring and has always been effective in the past. There's nothing else out at the moment to test it on though, but I'm pretty certain it's still viable. It's been kept in a very dry place, so it hasn't gotten wet, and I brush it on using a calligraphy brush. Often directly on to the aphids, as well as all surfaces of each leaf and stem.
Has anyone else had issues with these crazy super-aphids? They're the larger, green variety in my case - never seen any other species around my deck plants. Any suggestions aside from neem oil or garlic? I kind of want to be prepared in case they don't work. Never had to resort to anything aside from d. earth and aphid lions before...
