Pea aphids

The water blast method of getting rid of aphids is officially a failure. The crowders are COVERED in aphids-- more aphids than before. It appears that water blasting may actually cause them to multiply.

Here are the more useful things I learned:
Pea aphids overwinter on red clover, vetch or alfalfa. Awesome, since those are all great winter cover crops.

They don't, generally, lay eggs in NC, though they are capable of it. Instead, it appears that they have live baby aphids. Great. No pause to the sucking.

Apparently they are susceptible to a fungus of some kind that will kill them all pronto, but I couldn't find anything explaining how to introduce this dread disease, and when I tried, I discovered websites indicating that at some point in their evolution, pea aphids genetically morphed with some fungus and that is why they are green. Super great. Now the uugy aphids are kind of neat and interesting. . .
