Definitely aphids. I’ve had them on several plants in the past.
I have found a possible exacerbater of the problem, ants. We seem to have a lot of ants, who farm aphids to collect the sweet sticky substance created by aphids. I’m wondering if shrinking the ant population would also shrink the aphid population. Also, ant bites hurt.
I think I’ll have continue spraying insecticidal soap for now, eliminate some of the larger and nests, and when it starts warming up plant to attract more beneficial insects.
