These insects are plaguing the hot pepper plants in our greenhouse, and last year they killed the pepper plants that we brought indoors. I haven't noticed them being a problem when it was warmer out, I'm assuming the ladybugs were keeping them down.
How best to deal with them? We have an insecticidal soap that didn't work last year, tobacco plants that I could probably extract nicotine from, or I'm open to buying something if someone has a recommendation.
I live in Alberta, I think we're zone 3, if it helps
Hard to positively identify the species but it's looks a type of winged aphid.
Spray them off with a hose first to clear off the ones your can. If they do have wings you'll need to do some chemical control. I would apply pyrethrin or neem for longer control.
I really need a better picture of just one bug to positively identify it. Try taking a shot at maximum resolution (DPI) and maximum physical zoom.
