Very nice!
You have a class act there.
Really done your homework.

The dumping of the runt deserves no chagrin. (I just love that word)

Save your ire for "occasional tiny flies in the cabinet"!

Very bad news.
If you have a few flyers, you already have choke larvae munching your root hairs.

You need to address that right away.
Fungus gnat, are easy, dryer sheets will repel them and cutter yard spray will kill the larvae.
However if those flyers are mature root aphids, it's about to get ugly.

See if you can get a good closeup of the stuck buggers.
We'll get 'em identified.

Aloha,
Weeze
